MS12-020: Vulnerabilities in Remote Desktop Could Allow Remote Code Execution (2671387)

high Nessus Plugin ID 58332


The remote Windows host could allow arbitrary code execution.


An arbitrary remote code 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 has been 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.

This plugin also checks for a denial of service vulnerability in Microsoft Terminal Server.


Microsoft has released a set of patches for Windows XP, 2003, Vista, 2008, 7, and 2008 R2.
