CVE-2005-3416 Information

Description

phpBB 2.0.17 and earlier when register_globals is enabled and the session_start function has not been called to handle a session allows remote attackers to bypass security checks by setting the $_SESSION and $HTTP_SESSION_VARS variables to strings instead of arrays which causes an array_merge function call to fail.
