Description

w-Agora contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered when a specially-crafted URL request with an invalid parameter is passed to delete_forum.php, leading to a fatal error due to a call to an undefined function msgform() in delete_forum.php. The error information discloses the true path of the server-side scripts, resulting in a loss of confidentiality.
