MS12-036: Vulnerability in Remote Desktop Could Allow Remote Code Execution (2685939) (uncredentialed check)

This script is Copyright (C) 2012-2017 Tenable Network Security, Inc.


Synopsis :

The remote Windows host could allow arbitrary code execution.

Description :

An arbitrary remote code execution vulnerability exists in the
implementation of the Remote Desktop Protocol (RDP) on the remote
Windows host. The vulnerability is due to the way that RDP accesses
an object in memory that has been improperly initialized or deleted.

If RDP has been enabled on the affected system, an unauthenticated,
remote attacker could leverage this vulnerability to cause the system
to execute arbitrary code by sending a sequence of specially crafted
RDP packets to it.

Note that the Remote Desktop Protocol is not enabled by default.

Also note that this plugin tries to crash an affected system. It
works only under the following circumstances :

1) The remote system supports SSL for RDP security, and
2) The remote system has a 64-bit Operating System, and
3) The RDP server succeeds in allocating 4-GB of paged memory.
