Simple Machines Forum < 1.1.8 Password Reset Function Bypass

High Nessus Network Monitor Plugin ID 4813


The remote host is vulnerable to a security bypass flaw.


The remote host is running the Simple Machines Forum (SMF), a web forum. This version of SMF is vulnerable to a flaw where attackers can bypass security filtering related to the password reset function. The root cause of this flaw is reported to be the 'action' and 'reminder' parameters of index.php. An attacker exploiting this flaw would be able to reset the administrative password and gain full access to the application. In order for this attack to be successful, the attacker would need prior knowledge of the administrator nickname and numerical ID. Successful exploitation would result in the attacker gaining administrative access.


Upgrade to version 1.1.8 or higher.
