Unauthenticated session access via missing validation

Published Apr 18, 2025 · Updated Apr 22, 2025

Authentication bypass in DAEnetIP4 METO 1.25 allows remote attackers to access an authenticated session via /login_ok.htm. The endpoint grants access after a direct request without verifying that the requester completed authentication or holds a valid session. No credentials or user interaction are required, and the resulting session permits actions and data access with the privileges of the authenticated user.
