Vigil@nce: RealVNC, vulnerability of VNC Viewer

October 2008 by Vigil@nce

SYNTHESIS

An attacker can create a malicious VNC server and invite the
victim to connect to it with VNC Viewer in order to execute code
on the computer.

Gravity: 2/4

Consequences: user access/rights

Provenance: intranet server

Means of attack: no proof of concept, no attack

Ability of attacker: expert (4/4)

Confidence: confirmed by the editor (5/5)

Diffusion of the vulnerable configuration: high (3/3)

Creation date: 20/10/2008

IMPACTED PRODUCTS

 RealVNC

DESCRIPTION

The RealVNC product is composed of two modules:
 VNC Server: to be installed on the computer to administer
 VNS Viewer: to be installed on the client

The CMsgReader::readRect() function of the common/rfb/CMsgReader.cxx
file, used in VNC Viewer, does not correctly check received
messages.

An attacker can therefore create a malicious VNC server and invite
the victim to connect to it with VNC Viewer in order to execute
code on the computer.
