RealNetworks Helix Server 9 Administration Server Buffer Overflow
Several of Real Networks Helix Server products utilize a common
Administration Interface that is available over HTTP and protected by HTTP
An authenticated attacker can submit malformed HTTP POST requests to the
server's Administration interface, triggering a buffer overflow and
executing arbitrary code on the server.
On Windows platforms where the Helix Server is run as an NT Service, this
allows arbitrary code execution under the context of the NT SYSTEM
It should be noted that the Server does not have a default username and
password - these are set during installation. In addition to this, the
Server runs on a random TCP port, configured during installation.
* Helix Universal Mobile Server & Gateway 10, version 10.1.1.120 and
* Helix Universal Server and Gateway 9, version 22.214.171.1241 and prior
* RealSystem Server and Proxy version 8.x and earlier are not vulnerable
