TopList for phpBB list.php returnpath Parameter Remote File Inclusion
Remote / Network Access
Loss of Integrity
TopList contains a flaw that may allow a remote attacker to execute arbitrary commands. The issue is due to list.php not properly sanitizing user input supplied to the 'returnpath' variable. This may allow an attacker to include a file from a remote host that contains arbitrary commands which will be executed by the vulnerable script.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
