Descriptions

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.

Se descubrió un problema en SchedMD Slurm 23.02.x y 23.11.x. Hay un control de acceso incorrecto debido a una omisión de integridad de mensajes lenta. Un atacante puede reutilizar tokens de autenticación de nivel raíz durante la interacción con el proceso slurmd. Esto omite los hashes de mensajes RPC que protegen contra la reutilización no deseada de credenciales MUNGE. Las versiones fijas son 23.02.7 y 23.11.1.
