A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

Upgrade affected Slurm installations to versions 22.05.11, 23.02.7, or 23.11.1 or later, where this vulnerability is fixed.

Description

CVE-2023-49933 is a vulnerability in SchedMD Slurm versions 22.05.x, 23.02.x, and 23.11.x that involves improper enforcement of message integrity during transmission. This flaw allows attackers to modify RPC traffic to bypass message hash checks. Fixed versions are 22.05.11, 23.02.7, and 23.11.1.

Impact

An attacker could modify RPC traffic between components of Slurm, bypassing message hash checks intended to ensure message integrity. This could lead to unauthorized manipulation of communication within the system. No known exploits in the wild have been reported.

Summary

This vulnerability affects SchedMD Slurm versions 22.05.x, 23.02.x, and 23.11.x. It involves improper enforcement of message integrity in the communication channel, enabling attackers to alter RPC traffic in a way that bypasses message hash verification. The issue is resolved in versions 22.05.11, 23.02.7, and 23.11.1.
