Descriptions

A deserialization of untrusted data exists in EPM 2022 Su3 and all prior versions that allows an unauthenticated user to elevate rights. This exploit could potentially be used in conjunction with other OS (Operating System) vulnerabilities to escalate privileges on the machine or be used as a stepping stone to get to other network attached machines.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ivanti Endpoint Manager. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the ProcessEPMAuthToken method. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of NETWORK SERVICE.
