Name of the Vulnerable Software and Affected Versions SaltStack Salt versions prior to 3002.5

Description An issue was discovered in SaltStack Salt where the minion's restartcheck is vulnerable to command injection via a crafted process name. This allows for a local privilege escalation by any user able to create files on the minion in a non-blacklisted directory.

Recommendations For SaltStack Salt versions prior to 3002.5, update to version 3002.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the minion's restartcheck functionality to minimize the risk of exploitation. Additionally, restrict file creation capabilities in non-blacklisted directories to limit the potential for command injection attacks.
