CVE-2025-30041

Session ID disclosure via unauthenticated statistics endpoints

Published Aug 27, 2025 · Updated Aug 27, 2025

Missing authentication in CGM CLININET before 2025.MS1 allows remote attackers to read session IDs through three CGI statistics endpoints. The userlogstat.pl, usrlogstat.pl, and dblogstat.pl handlers return statistical data containing session identifiers without first establishing an authenticated session. The application server must be reachable from an adjacent network, and the documented consequence is session-identifier disclosure rather than confirmed session takeover.
