| Detailed Description |
The web server has the vulnerable CGI ad.cgi.
ad.cgi by Lief M. Wright is a Perl script freely available for managing rotating banner ads on the web page. This ad.cgi has a vulnerability that allows a remote attacker to execute arbitrary command due to insufficient checking of the input validation. When a remote attacker makes uses of the FORM method with a malicious input string such as shell metacharacters as the following request, this ad.cgi fails to correctly check user's input.
POST /cgi-bin/ad.cgi/../../../../../../../../bin/ping -c 5 www.victim.com HTTP/1.0
Thus, a remote attacker can execute arbitrary command on the system with privileges of the web server using this vulnerability.
* Note: This check solely relied on the presence of the relevant CGI to assess this vulnerability, so this might be a false positive.
