phpBB < 2.0.22 Multiple Vulnerabilities

critical Nessus Plugin ID 23968


The remote web server contains a PHP application that is affected by multiple vulnerabilities.


The version of phpBB installed on the remote host fails to properly block 'bad' redirection targets. In addition, it reportedly contains a non-persistent cross-site scripting flaw involving its private messaging functionality and several other issues. At a minimum, a remote attacker can leverage these flaws to launch cross-site scripting attacks against the affected application.


Upgrade to phpBB 2.0.22 or later.
