Description

Malware Scanner <= 4.7.2 and Web Application Firewall <= 2.1.1 - Unauthenticated Privilege Escalation

The Malware Scanner plugin and the Web Application Firewall plugin for WordPress (both by MiniOrange) are vulnerable to privilege escalation due to a missing capability check on the mo_wpns_init() function in all versions up to, and including, 4.7.2 (for Malware Scanner) and 2.1.1 (for Web Application Firewall). This makes it possible for unauthenticated attackers to escalate their privileges to that of an administrator.
