Authenticated code execution via unrestricted JSP upload
Published Oct 13, 2021 · Updated Aug 3, 2024
Unrestricted file upload in Zoho Corporation ADManager Plus Build 7111 and earlier allows remote authenticated users to execute code. The PasswordExpiryNotification REST handler accepts a JSP filename and body, writes the file beneath a web-served directory, and permits retrieval that executes the uploaded JSP. A valid low-privilege account and network access to the web interface are required; successful exploitation runs attacker-controlled code on the Windows host and can expose stored domain credentials.
