CVE-2024-13996
As a result, any pre-existing sessions (including those potentially controlled by an attacker) remained valid after a credential update.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.99%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Nagios XI versions prior to 2024R1.1.3 did not invalidate all other active sessions for a user when that user's password was changed. As a result, any pre-existing sessions (including those potentially controlled by an attacker) remained valid after a credential update. This insufficient session expiration could allow continued unauthorized access to user data and actions even after a password change.
