Vigil@nce - VMWare Tools: privilege elevation via tpfc.dll

September 2012 by Vigil@nce

This bulletin was written by Vigil@nce : http://vigilance.fr/offer

SYNTHESIS OF THE VULNERABILITY

A local attacker can create a malicious DLL, and use VMWare Tools, in order to obtain administration privileges.

Impacted products: ESX, VMware Player, VMware Workstation

Severity: 2/4

Creation date: 06/09/2012

DESCRIPTION OF THE VULNERABILITY

VMWare Tools are for example used to configure the display, or printing features.

The Windows printer configuration is done through ThinPrint tools. However, these tools load the library tpfc.dll, which does not exist on the system.

A local attacker can therefore create a malicious DLL with this name, and use VMWare Tools, in order to obtain administration privileges.
