Security vulnerability: Salt stack remote code execution CVE-2020-11651, CVE-2020-11652

This document (000019619) is provided subject to the disclaimer at the end of this document.

Environment

All SUSE maintained salt versions

Situation

Security researchers have identified bugs in the salt stack network protocol code that allowed unauthenticated remote attackers able to access the master over the network to inject files and so execute code as root users on the salt master systems.

All SUSE maintained salt versions are affected by this problem.

Resolution

SUSE is releasing updates for salt and strongly recommends our customers to update as soon as possible.

Cause

CVE-2020-11651
The salt-master process ClearFuncs class did not properly validate method calls. This allowed a remote attacker to access some methods without authentication. These methods can be used to retrieve user tokens from the salt master and/or run arbitrary commands on salt minions.

CVE-2020-11652
The salt-master process ClearFuncs class allowed access to some methods that improperly sanitize paths. These methods allow arbitrary directory access to authenticated users.

Status

Security Alert
