Description

An issue was discovered in SchedMD Slurm 23.02.x and 23.11.x. There is Incorrect Access Control because of a slurmd Message Integrity Bypass. An attacker can reuse root-level authentication tokens during interaction with the slurmd process. This bypasses the RPC message hashes that protect against undesired MUNGE credential reuse. The fixed versions are 23.02.7 and 23.11.1.

Affected products

• SchedMD Slurm: from 23.02 before 23.02.7; 23.11, 23.11-rc1 — fixed in 23.02.7

How to fix

Upgrade to a fixed version: SchedMD Slurm 23.02.7. Check the vendor advisory for mitigations.
