How to Fix CVE-2022-22967

To remediate this vulnerability, upgrade all affected Salt dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

salt fixed: 3002.9 
pip install salt>=3002.9
salt fixed: 3003.5 
pip install salt>=3003.5
salt fixed: 3004.2 
pip install salt>=3004.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show salt

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2022-22967, inspect your installed packages using pip:

pip show salt

Analyze the terminal output to locate any version of Salt in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3002.9), your application is affected.

Note: The pip show salt command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-863: Incorrect Authorization, where the product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. In Salt, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

An issue was discovered in SaltStack Salt in versions before 3002.9, 3003.5, 3004.2. PAM auth fails to reject locked accounts, which allows a previously authorized user whose account is locked still run Salt commands when their account is locked. This affects both local shell accounts with an active session and salt-api users that authenticate via PAM eauth.
