Description |
phpBB contains a flaw that may allow a remote attacker to bypass the globals deregistration code (register_globals). The flaw exists because the application starts not knowing the values of the $_SESSION or $HTTP_SESSION_VARS variables. It is possible a user can supply arbitrary values to these variables which will cause the register_globals setting to be ignored, allowing for cross-site scripting or SQL injection attacks.
