Noroxi assessment

Priority: Monitor (action score 7/100)

  • 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: 0.18% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. No special conditions are required; it is repeatable.
  • Fixed version: wazuh wazuh 4.13.0.

Low priority for now. Upgrade to wazuh wazuh 4.13.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Wazuh is a free and open source platform used for threat prevention, detection, and response. From version 4.3.0 to before 4.13.0, a missing ACL on "C:\Program Files (x86)\ossec-agent\authd.pass" exposes the password to all "Authenticated Users" on the local machine. This issue has been patched in version 4.13.0.
