CVE-2025-44823: Nagios Log Server before 2024R1.3.2 allows authenticated users to retrieve cleartext administrative API keys via a /nagioslogserver/index.ph

Noroxi assessment

Priority: Plan (action score 40/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 16.8% (FIRST EPSS); higher than 97% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.
