The remote host is vulnerable to a remote 'privilege escalation' flaw.
The remote host is running WebGUI, a content management framework. The remote version of this software is vulnerable to a flaw where an authenticated 'secondary admin' user can bypass security restrictions and gain administrative ability to add and modify user accounts. This would include the ability to create administrative accounts. An attacker exploiting this flaw would need a valid 'secondary admin' account.
Upgrade to version 7.4.18 or higher.
