Signature Detail

HTTP: phpBB Search Highlighting Arbitrary Command Execution

This signature detects attempts to exploit a known vulnerability in phpBB. Attackers can send a malformed HTTP request to phpBB to force phpBB to execute arbitrary PHP commands on the server with Web server permissions.

Extended Description

The 'viewtopic.php' phpBB script is prone to a remote script-injection vulnerability because the application fails to properly sanitize user-supplied URI parameters before using them to construct dynamically generated web pages. This issue may allow a remote attacker to execute arbitrary commands in the context of the webserver that is hosting the vulnerable software.
