Dashboard in Apple Mac OS X Tiger 10.4 allows attackers to execute arbitrary commands by overriding the behavior of system widgets via a user widget with the same bundle identifier (CFBundleIdentifier), a different vulnerability than CVE-2005-1474. This can allow a user-installed widget to override a system-installed one. Mac OS X is prone to a remote security vulnerability. ---------------------------------------------------------------------- Bist Du interessiert an einem neuen Job in IT-Sicherheit?

Jakarta Tomcat 5.0.19 (Coyote/1.1) and Tomcat 4.1.24 (Coyote/1.0) allows remote attackers to poison the web cache, bypass web application firewall protection, and conduct XSS attacks via an HTTP request with both a "Transfer-Encoding: chunked" header and a Content-Length header, which causes Tomcat to incorrectly handle and forward the body of the request in a way that causes the receiving server to process it as a separate HTTP request, aka "HTTP Request Smuggling.". A vulnerability in a common PHP extension module could allow a remote attacker to execute code on a vulnerable system. Multiple vendors' products are prone to HTTP-request-smuggling issues. Attackers can piggyback an HTTP request inside of another HTTP request. By leveraging failures to implement the HTTP/1.1 RFC properly, attackers can launch cache-poisoning, cross-site scripting, session-hijacking, and other attacks.

It did not cover the following cases: - - content-length header with chunked encoding over any HTTP connector - - multiple content-length headers over any AJP connector Requests with multiple content-length headers or with a content-length header when chunked encoding is being used should be rejected as invalid. When multiple components (firewalls, caches, proxies and Tomcat) process a sequence of requests where one or more requests contain either multiple content-length headers or a content-length header when chunked encoding is being used and several components do not reject the request and make different decisions as to which content-length header to use an attacker can poison a web-cache, perform an XSS attack and obtain sensitive information from requests other then their own. Tomcat now rejects requests with multiple content-length headers or with a content-length header when chunked encoding is being used. Mitigation: Users of affected versions should apply one of the following mitigations - - Upgrade to Apache Tomcat 8.0.0-RC3 or later (8.0.0-RC2 contains the fix but was not released) - - Upgrade to Apache Tomcat 7.0.47 or later (7.0.43 to 7.0.46 contain the fix but were not released) - - Upgrade to Apache Tomcat 6.0.39 or later (6.0.38 contains the fix but was not released) Credit: This issue was identified by the Apache Tomcat security team while investigating an invalid report related to CVE-2005-2090

Fortinet firewall running FortiOS 2.x contains a hardcoded username with the password set to the serial number, which allows local users with console access to gain privileges. Fortinet Firewall is prone to a remote security vulnerability. A local user with console access could exploit this vulnerability to gain privileges

Nortel VPN Router (aka Contivity) allows remote attackers to cause a denial of service (crash) via an IPsec IKE packet with a malformed ISAKMP header. Multiple Nortel Networks products are prone to a remote denial of service vulnerability. The issue manifests when the affected appliance processes an IKE main packet (ISAKMP) header of a certain type. When the packet is processed, the vulnerability is triggered and the device crashes, effectively denying service for legitimate users. Nortel VPN routers provide routing, VPN, firewall, bandwidth management, encryption, authentication, and data integrity functions for secure connections over IP networks and the Internet. A denial of service vulnerability exists in the Nortel VPN router product (formerly known as Nortel Contivity) when performing VPN security tests on users

Stack-based buffer overflow in the IMAP server for Ipswitch IMail 8.12 and 8.13, and other versions before IMail Server 8.2 Hotfix 2, allows remote authenticated users to cause a denial of service (crash) via a SELECT command with a large argument. Ipswitch IMail is prone to multiple remote vulnerabilities. Attackers may exploit these issues to deny service for legitimate users, obtaoin potentially sensitive information, and execute arbitrary code. The vulnerabilities include a directory-traversal issue, two remote denial-of-service issues, and multiple buffer-overflow issues. Ipswitch IMail server is a Windows-based communication and collaboration solution. However, this vulnerability cannot be further exploited. Ipswitch IMail IMAP SELECT Command DoS Vulnerability iDEFENSE Security Advisory 05.24.05 www.idefense.com/application/poi/display?id=241&type=vulnerabilities May 24, 2005 I. BACKGROUND Ipswitch IMail server is a Windows based messaging solution with a customer base of over 53 million users. More information about the application is available at: http://www.ipswitch.com/products/IMail_Server/index.html. II. The problem specifically exists in the handling of long arguments to the SELECT command. When a string approximately 260 bytes in size is supplied a stack-based buffer overflow occurs that results in an unhandled access violation forcing the daemon to exit. The issue is not believed to be further exploitable. III. ANALYSIS Successful exploitation allows remote to crash vulnerable IMAP servers and thereby prevent legitimate usage. The SELECT command is only available post authentication and therefore valid credentials are required to exploit this vulnerability IV. DETECTION iDEFENSE has confirmed the existence of this vulnerability in the latest version of Ipswitch IMAIL, version 8.13. Version 8.12 is also confirmed as vulnerable. It is suspected that earlier versions are vulnerable as well. V. WORKAROUND As this vulnerability is exploited after authentication occurs, ensuring that only trusted users have accounts can mitigate the risk somwhat. As a more effective workaround, consider limiting access to the IMAP server by filtering TCP port 143. If possible, consider disabling IMAP and forcing users to use POP3. VI. VENDOR RESPONSE The vendor has released the following patch to fix this vulnerability: ftp://ftp.ipswitch.com/Ipswitch/Product_Support/IMail/imail82hf2.exe The associated vendor advisory can be found at: http://www.ipswitch.com/support/imail/releases/imail_professional/im82hf 2.html VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CAN-2005-1254 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org), which standardizes names for security problems. VIII.

The IMAP daemon (IMAPD32.EXE) in Ipswitch Collaboration Suite (ICS) allows remote attackers to cause a denial of service (CPU consumption) via an LSUB command with a large number of null characters, which causes an infinite loop. Ipswitch IMail is prone to multiple remote vulnerabilities. Attackers may exploit these issues to deny service for legitimate users, obtaoin potentially sensitive information, and execute arbitrary code. The vulnerabilities include a directory-traversal issue, two remote denial-of-service issues, and multiple buffer-overflow issues. Attackers can use this vulnerability to cause the target service to crash. The cause of the vulnerability is the handling of extremely long parameters of the SELECT command. However, this vulnerability cannot be further exploited. Ipswitch IMail IMAP LSUB DoS Vulnerability iDEFENSE Security Advisory 05.24.05 www.idefense.com/application/poi/display?id=245&type=vulnerabilities May 24, 2005 I. BACKGROUND Ipswitch Collaboration Suite (ICS) is a comprehensive communication and collaboration solution for Microsoft Windows with a customer base of over 53 million users. More information is available on the vendor's website: http://www.ipswitch.com/products/IMail_Server/index.html II. The problem specifically exists within IMAPD32.EXE upon parsing a malformed LSUB command. An attacker can cause the daemon to produce heavy load by transmitting a long string of NULL characters to the 'LSUB' IMAP directive. This, in turn, causes an infinite loop, eventually exhausting all available system resources and causing a denial of service. III. ANALYSIS Exploitation allows unauthenticated remote attackers to render the IMAP server useless, thereby preventing legitimate users from retrieving e- mail. This attack takes few resources to launch and can be repeated to ensure that an unpatched system is unable to recover. Exploitation requires a valid IMAP account, thus limiting the impact of this vulnerability. IV. DETECTION iDEFENSE has confirmed the existence of this vulnerability in Ipswitch IMail version 8.13. It is suspected that earlier versions are also vulnerable. V.

Directory traversal vulnerability in the Web Calendaring server in Ipswitch Imail 8.13, and other versions before IMail Server 8.2 Hotfix 2, allows remote attackers to read arbitrary files via "..\" (dot dot backslash) sequences in the query string argument in a GET request to a non-existent .jsp file. Ipswitch IMail is prone to multiple remote vulnerabilities. Attackers may exploit these issues to deny service for legitimate users, obtaoin potentially sensitive information, and execute arbitrary code. The vulnerabilities include a directory-traversal issue, two remote denial-of-service issues, and multiple buffer-overflow issues. Ipswitch IMail server is a Windows-based communication and collaboration solution. There is a remote denial of service vulnerability in the Imail IMAP server of Ipswitch Inc. Attackers can use this vulnerability to cause the target service to crash. The cause of the vulnerability is the handling of extremely long parameters of the SELECT command. If the attacker can provide a string with a length of about 260 bytes, it may trigger a stack overflow and cause the daemon to exit. However, this vulnerability cannot be further exploited

Multiple stack-based buffer overflows in the IMAP server in IMail 8.12 and 8.13 in Ipswitch Collaboration Suite (ICS), and other versions before IMail Server 8.2 Hotfix 2, allow remote attackers to execute arbitrary code via a LOGIN command with (1) a long username argument or (2) a long username argument that begins with a special character. Ipswitch IMail is prone to multiple remote vulnerabilities. Attackers may exploit these issues to deny service for legitimate users, obtaoin potentially sensitive information, and execute arbitrary code. The vulnerabilities include a directory-traversal issue, two remote denial-of-service issues, and multiple buffer-overflow issues. Attackers can use this vulnerability to cause the target service to crash. However, this vulnerability cannot be further exploited. Ipswitch IMail IMAP LOGIN Remote Buffer Overflow Vulnerabilities iDEFENSE Security Advisory 05.24.05 www.idefense.com/application/poi/display?id=243&type=vulnerabilities May 24, 2005 I. BACKGROUND Ipswitch Collaboration Suite (ICS) is a comprehensive communication and collaboration solution for Microsoft Windows with a customer base of over 53 million users. More information is available on the vendor's website: http://www.ipswitch.com/products/IMail_Server/index.html II. The first vulnerability specifically exists in the handling of a long username to the LOGIN command. A long username argument of approximately 2,000 bytes will cause a stack based unicode string buffer overflow providing the attacker with partial control over EIP. As this vulnerability is in the LOGIN command itself, valid credentials are not required. The second vulnerability also exists in the handling of the LOGIN command username argument, however it lends itself to easier exploitation. If a large username starting with one of several special characters is specified, a stack overflow occurs, allowing an attacker to overwrite the saved instruction pointer and control execution flow. Included in the list of special characters are the following: % : * @ & Both of these vulnerabilities can lead to the execution of arbitrary code. III. Valid credentials are not required to for exploitation, which heightens the impact of this vulnerability. IV. DETECTION iDEFENSE has confirmed the existence of this vulnerability in the latest version of Ipswitch IMAIL, version 8.13. Version 8.12 is also confirmed as vulnerable. It is suspected that earlier versions are also vulnerable. V. WORKAROUND As this vulnerability is exploited before authentication occurs, the only effective workaround is to limit access to the IMAP server by filtering TCP port 143. If possible, consider disabling IMAP and forcing users to use POP3. VI.

Stack-based buffer overflow in the IMAP daemon (IMAPD32.EXE) in IMail 8.13 in Ipswitch Collaboration Suite (ICS), and other versions before IMail Server 8.2 Hotfix 2, allows remote authenticated users to execute arbitrary code via a STATUS command with a long mailbox name. Ipswitch IMail is prone to multiple remote vulnerabilities. Attackers may exploit these issues to deny service for legitimate users, obtaoin potentially sensitive information, and execute arbitrary code. The vulnerabilities include a directory-traversal issue, two remote denial-of-service issues, and multiple buffer-overflow issues. Attackers can use this vulnerability to cause the target service to crash. However, this vulnerability cannot be further exploited. Ipswitch IMail IMAP STATUS Remote Buffer Overflow Vulnerability iDEFENSE Security Advisory 05.24.05 www.idefense.com/application/poi/display?id=244&type=vulnerabilities May 24, 2005 I. BACKGROUND Ipswitch Collaboration Suite (ICS) is a comprehensive communication and collaboration solution for Microsoft Windows with a customer base of over 53 million users. More information is available on the vendor's website: http://www.ipswitch.com/products/IMail_Server/index.html II. The vulnerability specifically exists in the handling of a long mailbox name to the STATUS command. A long mailbox name argument will cause a stack based buffer overflow, providing the attacker with full control over the saved return address on the stack. Once this has been achieved, execution of arbitrary code becomes trivial. As this vulnerability is in the STATUS command, which requires that a session is authenticated, valid credentials are required. III. Valid credentials are required for exploitation, which lessens the impact of this vulnerability. IV. DETECTION iDEFENSE has confirmed the existence of this vulnerability in Ipswitch IMail version 8.13. It is suspected that earlier versions are also vulnerable. V. WORKAROUND As this vulnerability is exploited after authentication occurs, ensuring that only trusted users have accounts can mitigate the risk somwhat.

Gibraltar Firewall 2.2 and earlier, when using the ClamAV update to 0.81 for Squid, uses a defunct ClamAV method to scan memory for viruses, which does not return an error code and prevents viruses from being detected. Gibraltar is susceptible to an antivirus scan evasion vulnerability. This issue presents itself because of an oversight in the design of the firewall product, due to a change of features of the ClamAV antivirus scanning engine. This vulnerability allows malicious content to pass undetected by an affected firewall acting as an HTTP proxy, leading to a false sense of security

Dashboard in Apple Mac OS X 10.4.1 allows remote attackers to install widgets via Safari without prompting the user, a different vulnerability than CVE-2005-1933. This issue is due to Safari improperly considering Dashboard widgets to be "safe" content. It is demonstrated that an attacker can cause Safari to automatically download, and then install widgets into the users '~/Library/Widgets' directory. This happens without user intervention or notification. Reportedly, once widgets have been automatically installed via Safari, the normal validation required for widgets to gain access to system resources is skipped, allowing complete system access to the malicious widgets, however, this has not been confirmed by Symantec. This will likely result in malicious script, or machine code being executed in the context of the targeted user. Mac OS X version 10.4 is vulnerable to this issue

SecurityAgent in Apple Mac OS X 10.4.1 allows attackers with physical access to bypass the locked screensaver and launch background applications by opening a URL from a text input field. Apple Mac OS X is susceptible to a screen saver contextual menu access vulnerability. This issue presents itself when a user locks their screen. When the screen saver prompts for the password when a user attempts to unlock the screen, contextual menus are available in the text-input fields. Attackers may be able to partially bypass locked-screen restrictions. This may allow attackers to cause inappropriate, incriminating, or otherwise unwanted Web sites to be displayed on targeted computers. It may also allow them to exploit other latent vulnerabilities in applications used to handle URIs, by opening malicious Web sites or network resources. An attacker could exploit this vulnerability to partially bypass lock screen restrictions, display inappropriate sites and launch background applications on the target machine

D-Link DSL-502T, DSL-504T, DSL-562T, and DSL-G604T, when /cgi-bin/firmwarecfg is executed, allows remote attackers to bypass authentication (1) if their IP address already exists in /var/tmp/fw_ip or (2) if their request is the first, which causes /var/tmp/fw_ip to be created and contain their IP address. DSL-562T is prone to a security bypass vulnerability

D-Link DSL-504T allows remote attackers to bypass authentication and gain privileges, such as upgrade firmware, restart the router or restore a saved configuration, via a direct request to firmwarecfg. D-Link DSL routers are commonly used routers in homes and small offices.  D-Link DSL routers have problems with user authentication. Remote attackers could use this vulnerability to gain unauthorized access to devices.  When executing CGI / cgi-bin / firmwarecfg, the script checks if the fw_ip file exists in / var / tmp /. If this file exists, all IP addresses listed therein will be allowed to access the device directly without authentication. If this file does not exist, CGI will create a new file with the requested address written in it.  If the web configuration console can be accessed from the Internet and no one has called CGI before, any user can access the router, download the config.xml file containing the user account and password, and cause access to the private network, modify or change the router's firmware Wait. This issue is due to a failure of the devices to require authentication in certain circumstances. Various D-Link devices with the following firmware revisions are affected by this issue: - V1.00B01T16.EN.20040211 - V1.00B01T16.EU.20040217 - V0.00B01T04.UK.20040220 - V1.00B01T16.EN.20040226 - V1.00B02T02.EU.20040610 - V1.00B02T02.UK.20040618 - V1.00B02T02.EU.20040729 - V1.00B02T02.DE.20040813 - V1.00B02T02.RU.20041014 Due to the common practice of code reuse, other devices are also likely affected by this issue. ---------------------------------------------------------------------- Bist Du interessiert an einem neuen Job in IT-Sicherheit?

Certain system calls in Apple Mac OS X 10.4.1 do not properly enforce the permissions of certain directories without the POSIX read bit set, but with the execute bits set for group or other, which allows local users to list files in otherwise restricted directories. Apple Mac OS X is susceptible to a local information disclosure vulnerability. This is due to a failure of the operating system to properly implement POSIX permissions checking in certain circumstances. This vulnerability allows local attackers to retrieve normally forbidden names contained in directories. This scenario is commonly used to obscure access to public directories (such as '~/Public/Drop Box') for security reasons, as users are required to have knowledge about already existing files contained in these directories to be able to access them

Certain TCP implementations may allow a remote attacker to arbitrarily modify host timestamp values, leading to a denial-of-service condition. A denial-of-service vulnerability exists for the TCP RFC 1323. The issue resides in the Protection Against Wrapped Sequence Numbers (PAWS) technique that was included to increase overall TCP performance. When TCP 'timestamps' are enabled, both hosts at the endpoints of a TCP connection employ internal clocks to mark TCP headers with a 'timestamp' value. The issue manifests if an attacker transmits a sufficient TCP PAWS packet to a vulnerable computer. The attacker sets a large value as the packet timestamp. When the target computer processes this packet, the internal timer is updated to the large value that the attacker supplied. This causes all other valid packets that are received subsequent to an attack to be dropped, because they are deemed to be too old or invalid. This type of attack will effectively deny service for a target connection. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ============================================================================= FreeBSD-SA-05:15.tcp Security Advisory The FreeBSD Project Topic: TCP connection stall denial of service Category: core Module: inet Announced: 2005-06-29 Credits: Noritoshi Demizu Affects: All FreeBSD releases. Corrected: 2005-06-29 21:38:48 UTC (RELENG_5, 5.4-STABLE) 2005-06-29 21:41:03 UTC (RELENG_5_4, 5.4-RELEASE-p3) 2005-06-29 21:42:33 UTC (RELENG_5_3, 5.3-RELEASE-p17) 2005-06-29 21:43:42 UTC (RELENG_4, 4.11-STABLE) 2005-06-29 21:45:14 UTC (RELENG_4_11, 4.11-RELEASE-p11) 2005-06-29 21:46:15 UTC (RELENG_4_10, 4.10-RELEASE-p16) CVE Name: CAN-2005-0356, CAN-2005-2068 For general information regarding FreeBSD Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit <URL:http://www.freebsd.org/security/>. I. Background The Transmission Control Protocol (TCP) of the TCP/IP protocol suite provides a connection-oriented, reliable, sequence-preserving data stream service. TCP packets with the SYN flag set are used during setup of new TCP connections. II. Problem Description Two problems have been discovered in the FreeBSD TCP stack. First, when a TCP packets containing a timestamp is received, inadequate checking of sequence numbers is performed, allowing an attacker to artificially increase the internal "recent" timestamp for a connection. Second, a TCP packet with the SYN flag set is accepted for established connections, allowing an attacker to overwrite certain TCP options. III. Impact Using either of the two problems an attacker with knowledge of the local and remote IP and port numbers associated with a connection can cause a denial of service situation by stalling the TCP connection. The stalled TCP connection my be closed after some time by the other host. IV. Workaround In some cases it may be possible to defend against these attacks by blocking the attack packets using a firewall. Packets used to effect either of these attacks would have spoofed source IP addresses. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to 4-STABLE or 5-STABLE, or to the RELENG_5_4, RELENG_5_3, RELENG_4_11, or RELENG_4_10 security branch dated after the correction date. 2) To patch your present system: The following patches have been verified to apply to FreeBSD 4.10, 4.11, 5.3, and 5.4 systems. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility.
