CVE-2022-28219 is an unauthenticated remote code execution vulnerability affecting Zoho ManageEngine ADAudit Plus, a compliance tool used by enterprises to monitor changes to Active Directory. The vulnerability comprises several issues: untrusted Java deserialization, path traversal, and a blind XML External Entities (XXE) injection. This is a vulnerability that NodeZero, our autonomous pentesting product, has exploited to not only execute code remotely, but in some cases compromise domain administrator accounts. If you’re running ADAudit Plus in your enterprise, we strongly recommend upgrading to build 7060 or later to fix this vulnerability.
We regularly encounter ManageEngine products in internal pentests. The products related to Active Directory management (ADManager Plus, ADSelfService Plus, ADAudit Plus, etc) are especially prevalent. These applications are also attractive to attackers because of the privileged access they have to Active Directory. We decided to take a closer look at ADAudit Plus to see what we could find.
