SquirrelMail contrib/decrypt_headers.php XSS

This script is Copyright (C) 2009-2012 Tenable Network Security, Inc.


Synopsis :

The remote webmail application is affected by a cross-site scripting
vulnerability.

Description :

The installed version of SquirrelMail fails to sanitize user-supplied
input before using it in the 'contrib/decrypt_headers.php' script to
dynamically generate HTML.

An unauthenticated attacker can exploit this issue to launch
cross-site scripting attacks against the affected application.

There are also reportedly several other issues, including cross-site
scripting vulnerabilities, a code injection vulnerability, and a
session fixation vulnerability, though Nessus has not tested for
these.
