Vigil@nce: RuggedCom ROS, usage of a constant RSA key

September 2012 by Vigil@nce

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

SYNTHESIS OF THE VULNERABILITY

The RuggedCom ROS system contains a constant RSA key, which is
used to establish SSL sessions.

 Impacted products: RuggedSwitch
 Severity: 2/4
 Creation date: 21/08/2012

DESCRIPTION OF THE VULNERABILITY

A SSL tunnel can be established using a RSA key pair (public and
private). This key pair should be different on each service.

However, the RuggedCom ROS system contains a constant hardcoded
RSA key, which is used to establish SSL sessions.

An attacker who knows the private RSA key can therefore decrypt
SSL exchanges of RuggedCom ROS.
