The _prolog_error function in slurmd/req.c in Slurm before 15.08.13, 16.x before 16.05.7, and 17.x before 17.02.0-pre4 has a vulnerability in how the slurmd daemon informs users of a Prolog failure on a compute node. That vulnerability could allow a user to assume control of an arbitrary file on the system. Any exploitation of this is dependent on the user being able to cause or anticipate the failure (non-zero return code) of a Prolog script that their job would run on. This issue affects all Slurm versions from 0.6.0 (September 2005) to present. Workarounds to prevent exploitation of this are to either disable your Prolog script, or modify it such that it always returns 0 ("success") and adjust it to set the node as down using scontrol instead of relying on the slurmd to handle that automatically. If you do not have a Prolog set you are unaffected by this issue.

Insecure SPANK environment variable handling exists in SchedMD Slurm before 16.05.11, 17.x before 17.02.9, and 17.11.x before 17.11.0rc2, allowing privilege escalation to root during Prolog or Epilog execution.

SchedMD Slurm before 17.02.11 and 17.1x.x before 17.11.7 mishandles user names (aka user_name fields) and group ids (aka gid fields).

SchedMD Slurm before 17.02.10 and 17.11.x before 17.11.5 allows SQL Injection attacks against SlurmDBD.

SchedMD Slurm 17.11.x, 18.08.0 through 18.08.7, and 19.05.0 allows SQL Injection.

SchedMD Slurm before 18.08.9 and 19.x before 19.05.5 has weak slurmdbd.conf permissions.

SchedMD Slurm before 18.08.9 and 19.x before 19.05.5 executes srun --uid with incorrect privileges.

SchedMD Slurm before 17.11.13 and 18.x before 18.08.5 mishandles 32-bit systems.

Slurm 19.05.x before 19.05.7 and 20.02.x before 20.02.3, in the rare case where Message Aggregation is enabled, allows Authentication Bypass via an Alternate Path or Channel. A race condition allows a user to launch a process as an arbitrary user.

Slurm before 19.05.8 and 20.x before 20.02.6 has an RPC Buffer Overflow in the PMIx MPI plugin.

Slurm before 19.05.8 and 20.x before 20.02.6 exposes Sensitive Information to an Unauthorized Actor because xauth for X11 magic cookies is affected by a race condition in a read operation on the /proc filesystem.

SchedMD Slurm before 20.02.7 and 20.03.x through 20.11.x before 20.11.7 allows remote code execution as SlurmUser because use of a PrologSlurmctld or EpilogSlurmctld script leads to environment mishandling.

SchedMD Slurm 21.08.* before 21.08.4 has Incorrect Access Control. On sites using the new AccountingStoreFlags=job_script and/or job_env options, the access control rules in SlurmDBD may permit users to request job scripts and environment files to which they should not have access.

SchedMD Slurm 21.08.x through 20.11.x has Incorrect Access Control that leads to Information Disclosure.

SchedMD Slurm 21.08.x through 20.11.x has Incorrect Access Control that leads to Escalation of Privileges and code execution.

SchedMD Slurm 21.08.x through 20.11.x has Incorrect Access Control that leads to Escalation of Privileges.

SchedMD Slurm 23.02.x before 23.02.6 and 22.05.x before 22.05.10 allows filesystem race conditions for gaining ownership of a file, overwriting a file, or deleting files.

An issue was discovered in SchedMD Slurm 22.05.x, 23.02.x, and 23.11.x. There is Improper Enforcement of Message Integrity During Transmission in a Communication Channel. This allows attackers to modify RPC traffic in a way that bypasses message hash checks. The fixed versions are 22.05.11, 23.02.7, and 23.11.1.

An issue was discovered in SchedMD Slurm 23.11.x. There is SQL Injection against the SlurmDBD database. The fixed version is 23.11.1.

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.

An issue was discovered in SchedMD Slurm 22.05.x, 23.02.x, and 23.11.x. A NULL pointer dereference leads to denial of service. The fixed versions are 22.05.11, 23.02.7, and 23.11.1.

An issue was discovered in SchedMD Slurm 22.05.x, 23.02.x, and 23.11.x. Because of a double free, attackers can cause a denial of service or possibly execute arbitrary code. The fixed versions are 22.05.11, 23.02.7, and 23.11.1.

An issue was discovered in SchedMD Slurm 22.05.x and 23.02.x. There is Incorrect Access Control: an attacker can modified their extended group list that is used with the sbcast subsystem, and open files with an unauthorized set of extended groups. The fixed versions are 22.05.11 and 23.02.7.
