Detailed Description A version of phpBB software which is older or as old as than version 2.0.16 is detected as installed on the host. phpBB is a open-source bulletin board software package, which uses MySQL, MS-SQL, PostgreSQL or Access/ODBC database. phpBB2 2.0.16 versions and earlier are vulnerable to a cross-site scripting vulnerability, caused by improper validation of user-supplied input passed to BBCode containing nested URL tags. This vulnerability could permit a remote attacker to create a malicious URI link that includes hostile HTML and script code. If this link were to be followed, the hostile code may be rendered in the web browser of the victim user. This would occur in the security context of the affected web site and may allow for theft of cookie-based authentication credentials or other attacks.

* Note: This check solely relied on the version number of the phpBB software installed on the remote Web server to assess this vulnerability, so this might be a false positive.
