Summary

In order to perform actions that requires higher privileges, the Quest KACE System Management Appliance 8.0.318 relies on a message queue managed that runs with root privileges and only allows a set of commands. One of the available commands allows changing any user's password (including root). A low-privilege user could abuse this feature by changing the password of the 'kace_support' account, which comes disabled by default but has full sudo privileges.

Exploit prediction

2.97% chance of exploitation in the next 30 days, higher than 87% of all scored CVEs (FIRST EPSS, 2026-11-08).
