Vulnerability Note VU#497400
phpBB viewtopic.php fails to properly sanitize input passed to the "highlight" parameter
phpBB contains an user input validation problem with regard to the parsing of the URL. An intruder can deface a phpBB website, execute arbitrary commands, or gain administrative privileges on a compromised bulletin board.
phpBB is an open-source bulletin board. A lack of input validation on the highlight parameter supplied to viewtopic.php may allow a remote attacker to execute arbitrary commands on a vulnerable server. The problem occurs because phpBB does not scan incoming URLs for malicious content when they are decoded.
