Name of the Vulnerable Software and Affected Versions Red Hat Enterprise Virtualization Manager (RHEV-M) version 4.0

Description The issue allows physically proximate attackers to bypass a webadmin session timeout restriction. This is achieved via vectors related to UI selections, which trigger repeating queries.

Recommendations For RHEV-M version 4.0, consider implementing a custom session timeout mechanism to mitigate the risk of session bypass. As a temporary workaround, restrict access to the webadmin interface to minimize the risk of exploitation.
