One of the components of DiskXtender is the File System Manager, which is used to create and manage backups. For more information see the vendor's website at the following URL.


Remote exploitation of a buffer overflow vulnerability in EMC Corp.'s DiskXtender could allow an attacker to execute arbitrary code with the privileges of the affected service.

The File System Manager is prone to a stack-based buffer overflow vulnerability. When handling requests on the RPC interface with UUID b157b800-aef5-11d3-ae49-00600834c15f, the service does not properly validate the length of a string in the request. By making a specially crafted request, a stack based buffer overflow occurs.


Exploitation of this vulnerability results in the execution of arbitrary code with the privileges of the affected service, usually SYSTEM. In order to exploit this vulnerability, authentication is required.
