Exploitation evidence

Detectable: no evidence on record.
No public nuclei template indexed

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 or the CVSS exploit maturity 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

Fixed versions 23.02.7 and 23.11.1 have been released to address this vulnerability. Users should upgrade to these versions or later to remediate the issue. No other mitigation or temporary workaround is indicated.

Description

CVE-2023-49935 is a vulnerability in SchedMD Slurm versions 23.02.0 through 23.02.6 and version 23.11.0 that allows incorrect access control due to a slurmd message integrity bypass. This flaw enables an attacker to reuse root-level authentication tokens by bypassing the RPC message hashes that are designed to prevent unauthorized reuse of MUNGE credentials. Fixed versions 23.02.7 and 23.11.1 address this issue.
