Improper Restriction of XML External Entity Reference
An External XML entity (XXE) vulnerability in ePO prior to 5.10 Update 14 can lead to an unauthenticated remote attacker to potentially trigger a Server Side Request Forgery attack. This can be exploited by mimicking the Agent Handler call to ePO and passing the carefully constructed XML file through the API.
