CVE-2025-40636Network attack vector

Database-content retrieval via visit-counter cookie injection

Published Oct 3, 2025 · Updated Oct 3, 2025

SQL injection in Vinaora Visitors Counter 2.0.4j3 allows remote attackers to retrieve database content through a crafted cookie. The visit-counting path uses the cip_vvisitcounter cookie in database operations without neutralizing SQL syntax; INCIBE has not identified the file or function. Any endpoint that loads the module and counts a visit exposes the unauthenticated network path, with the documented consequence bounded to database-content retrieval.
