MISP before 2.4.115 allows privilege escalation in certain situations. After updating to 2.4.115, escalation attempts are blocked by the __checkLoggedActions function with a "This could be an indication of an attempted privilege escalation on older vulnerable versions of MISP (<2.4.115)" message.
app/Model/Server.php in MISP 2.4.109 allows remote command execution by a super administrator because the PHP file_exists function is used with user-controlled entries, and phar:// URLs trigger deserialization.
