Remote code execution via path traversal file write
Published Nov 11, 2021 · Updated Aug 4, 2024
Path traversal in Zoho ManageEngine ADAudit Plus 7005 and earlier allows remote attackers to write executable files outside the intended report directory. The GPO watcher data endpoint accepts traversal sequences in Html_fileName and writes attacker-controlled htmlReport content into the alert_scripts directory. The documented execution chain requires an account permitted to create alert scripts and a configured Active Directory domain, then triggers the uploaded script through a failed domain login.
