Low · 2.9 Public exploit CVE-2021-34428 EUVD-2021-1354GHSA-m6cp-vxjx-65j6

SessionListener can prevent a session from being invalidated breaking logout

Published Jun 22, 2021 · Updated Aug 4, 2024 · Assigned by eclipse

Vendor: The Eclipse Foundation Product: Eclipse Jetty Package: jetty Package: jetty8 Package: jetty9 Package: jetty9 Package: org.eclipse.jetty:jetty-server Ecosystem: Debian Ecosystem: Maven Ecosystem: Ubuntu

Description

For Eclipse Jetty versions <= 9.4.40, <= 10.0.2, <= 11.0.2, if an exception is thrown from the SessionListener#sessionDestroyed() method, then the session ID is not invalidated in the session ID manager. On deployments with clustered sessions and multiple contexts this can result in a session not being invalidated. This can result in an application used on a shared computer being left logged in.
