CVE-2024-28830: Automation user secrets written to audit log

Noroxi assessment

Priority: Monitor (action score 10/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.33% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Checkmk GmbH Checkmk 2.1.0p45, 2.2.0p28, 2.3.0p7.

Low priority for now. Upgrade to Checkmk GmbH Checkmk 2.1.0p45, 2.2.0p28, 2.3.0p7 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Insertion of Sensitive Information into Log File in Checkmk GmbH's Checkmk versions <2.3.0p7, <2.2.0p28, <2.1.0p45 and <=2.0.0p39 (EOL) causes automation user secrets to be written to audit log files accessible to administrators.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
