Name of the Vulnerable Software and Affected Versions SchedMD Slurm versions 23.02.x through 23.02.6 SchedMD Slurm versions 23.11.x through 23.11.0

Description The issue is related to incorrect access control due to a slurmd Message Integrity Bypass, allowing an attacker to reuse root-level authentication tokens during interaction with the slurmd process. This bypasses the RPC message hashes that protect against undesired MUNGE credential reuse.

Recommendations For SchedMD Slurm versions 23.02.x through 23.02.6, update to version 23.02.7 to resolve the issue. For SchedMD Slurm versions 23.11.x through 23.11.0, update to version 23.11.1 to resolve the issue. As a temporary workaround, consider restricting access to the slurmd process to minimize the risk of exploitation.
