CVE-2025-66963

Sensitive-data disclosure via ineffective session logout

Published Dec 15, 2025 · Updated Dec 15, 2025

Insufficient session expiration in Hitron HI3120 7.2.4.5.2b1 allows local users to access sensitive data through a logged-out session. The Logout option in /webpages/index.html leaves the authenticated session active instead of invalidating it. An attacker with local access and low privileges can continue using the abandoned session to read protected information; no integrity or availability impact is reported.
