CVE-2024-13996

CRITICAL

Nagios XI < 2024R1.1.3 - Insufficient Session Expiration

Title source: llm
STIX 2.1

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.
