Description
This module checks for the OpenSSL ChangeCipherSpec (CCS)
Injection vulnerability. The problem exists in the handling of early
CCS messages during session negotiation. Vulnerable installations of OpenSSL accepts
them, while later implementations do not. If successful, an attacker can leverage this
vulnerability to perform a man-in-the-middle (MITM) attack by downgrading the cipher spec
between a client and server. This issue was first reported in early June, 2014.
