Authentication is not required to exploit this vulnerability.
The flaw exists within the cstore.exe component which listens by default on TCP port 52005. When handling a CONTENT_STORE_ADMIN_REQ packet type the process trusts length value provided by the 'cs_anams' parameter and blindly copies user supplied data into a fixed-length buffer on the stack. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the SYSTEM user.
