Vigil@nce - BlackBerry Enterprise Service: information disclosure via activity log files

August 2014 by Vigil@nce

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

SYNTHESIS OF THE VULNERABILITY

An attacker can trigger an error with Enterprise Instant Messenger of BlackBerry Enterprise Service, in order to obtain sensitive information.

Impacted products: BES

Severity: 2/4

Creation date: 14/08/2014

DESCRIPTION OF THE VULNERABILITY

The BlackBerry Enterprise Service product offers an Instant Messaging function.

Access to this service requires creation of a communication session and user authentication. However, in some cases, when an error occurs at the beginning or the end of session, the server records in its activity logs the secrets used for communication encryption or user authentication.

An attacker who can read the activity log files can therefore get sensitive information.
