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

high Nessus Plugin ID 58332
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Windows host could allow arbitrary code execution.

Description

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.

Solution

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