ID CVE-2017-15013
Summary OpenText Documentum Content Server (formerly EMC Documentum Content Server) through 7.3 contains the following design gap, which allows an authenticated user to gain superuser privileges: Content Server stores information about uploaded files in dmr_content objects, which are queryable and "editable" (before release 7.2P02, any authenticated user was able to edit dmr_content objects; now any authenticated user may delete a dmr_content object and then create a new one with the old identifier) by authenticated users; this allows any authenticated user to replace the content of security-sensitive dmr_content objects (for example, dmr_content related to dm_method objects) and gain superuser privileges.

CWE CWE-269

  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.
