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
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.
