Kerio Connect 8.2.x < 8.2.4 Heartbeat Information Disclosure (Heartbleed)
High Nessus Plugin ID 76402
The remote mail server is affected by the Heartbleed vulnerability
According to its banner, the remote host is running a version of Kerio Connect (formerly Kerio MailServer) version 8.2.x prior to 8.2.4. It is, therefore, affected by an out-of-bounds read error, known as the 'Heartbleed Bug' in the included OpenSSL version. This error is related to handling TLS heartbeat extensions that could allow an attacker to obtain sensitive information such as primary key material, secondary key material, and other protected content. Note this affects both client and server modes of operation. Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
