## Affected

- WatchGuard SSO Agent: from 12.0, through 12.10.2

## Description

Incorrect Authorization vulnerability in WatchGuard Authentication Gateway (aka Single Sign-On Agent) on Windows allows an attacker with network access to execute restricted management commands. An attacker that has already gained network access could exploit this vulnerability to retrieve authenticated usernames and group memberships from the Single Sign-On Agent or tamper with the agent configuration. This vulnerability cannot be used by an attacker to gain access to user credentials.
