CVE-2020-15218Network attack vector

Admin-page disclosure via persistent browser cache

Published Jan 13, 2021 · Updated Aug 4, 2024

Insufficient session expiration in Combodo iTop before 2.7.2 and before 3.0.0 allows attackers to view cached admin pages after logout. Affected admin responses permit browser caching and framing, leaving rendered content in navigation history instead of preventing its reuse. Exposure requires prior authenticated access and subsequent access to the same browser context; the documented consequence is disclosure of cached admin content.
