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.

Affected products

Phpbb Group Phpbb: 2.0.0, 2.0.1, 2.0.2, 2.0.3, 2.0.4, 2.0.5 (+21)
