Supplied commands can list file names, show the contents of the password file, or install a backdoor to name a few actions that an attacker may attempt. -- Affected Systems: Hosts running CCBill software that has the whereami.cgi in the server's CGI path. -- Attack Scenarios: An attacker can send a request to execute an arbitrary command. -- Ease of Attack: Simple. -- False Positives: None Known. -- False Negatives: None Known. -- Corrective Action: Remove the whereami.cgi command. -- Contributors: Sourcefire Research Team Judy Novak <judy.novak@sourcefire.com> -- Additional References: bugtraq http://www.securityfocus.com/bid/8095 --
