CVE-2024-13996
Nagios XI < 2024R1.1.3 Session Not Invalidated After Password Change
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.

Action Type Old Value New Value Added Translation Title: XI de Nagios, Description: Las versiones de Nagios XI anteriores a 2024R1.1.3 no invalidaban todas las demás sesiones activas para un usuario cuando se cambiaba la contraseña de ese usuario. Como resultado, cualquier sesión preexistente (incluidas aquellas potencialmente controladas por un atacante) permanecían válidas después de una actualización de credenciales. Esta expiración de sesión insuficiente podría permitir el acceso no autorizado continuado a los datos y acciones del usuario incluso después de un cambio de contraseña. -
