CVE-2018-7890

Name of the Vulnerable Software and Affected Versions: Zoho ManageEngine Applications Manager versions prior to 13.6 (build 13640)

Description: A remote code execution issue was discovered. The publicly accessible "testCredential.do" endpoint takes multiple user inputs and validates supplied credentials by accessing a specified system. This endpoint calls several internal classes, and then executes a PowerShell script. If the specified system is OfficeSharePointServer, then the username and password parameters to this script are not validated, leading to Command Injection.

Recommendations: For versions prior to 13.6 (build 13640), update to version 13.6 (build 13640) or later to resolve the issue. As a temporary workaround, consider restricting access to the "testCredential.do" endpoint until a patch is available. Avoid using the username and password parameters in the affected endpoint when the specified system is OfficeSharePointServer until the issue is resolved.
