CVE-2024-38863: CSRF token leaked in URL parameters

Noroxi assessment

Priority: Monitor (action score 20/100)

  • 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: 0.41% (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 2.1.0p48, 2.2.0p35, 2.3.0p18.
  • Severity is disputed: the assigning authority (CNA) scores it 2.0, NVD 5.1.

Low priority for now. Upgrade to Checkmk GmbH Checkmk 2.1.0p48, 2.2.0p35, 2.3.0p18 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Exposure of CSRF tokens in query parameters on specific requests in Checkmk GmbH's Checkmk versions <2.3.0p18, <2.2.0p35 and <2.1.0p48 could lead to a leak of the token to facilitate targeted phishing attacks.
