Application does not limit the number or frequency of user interactions, such as the number of incoming requests. At the "/EPMUI/VfManager.asmx/ChangePassword" endpoint it is possible to perform a brute force attack on the current password in use.

This issue affects CyberArk Endpoint Privilege Manager in SaaS version 24.7.1. The status of other versions is unknown. After multiple attempts to contact the vendor we did not receive any answer.
