CVE-2018-11134
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.97%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
