The Common Vulnerabilities and Exposures project identifies the following problems: Private messaging allowed cross site request forgery, making it possible to delete all private messages of a user by sending them to a crafted web page. Cross site request forgery enabled an attacker to perform various actions on behalf of a logged in user. (Applies to sarge only.) A negative start parameter could allow an attacker to create invalid output. (Applies to sarge only.) Redirection targets were not fully checked, leaving room for unauthorised external redirections via a phpBB forum. (Applies to sarge only.)
