Summary
The OpenSSL library used in IBM Campaign and Contact Optimization is
vulnerable to TLS protocol downgrade attack.
Vulnerability Details
CVEID: CVE-2014-3511
DESCRIPTION:
A flaw in the OpenSSL SSL/TLS server code causes the server to negotiate TLS
1.0 instead of higher protocol versions when the ClientHello message is badly
fragmented. This allows a man-in-the-middle attacker to force a downgrade to
TLS 1.0 even if both the server and the client support a higher protocol
version, by modifying the client's TLS records.
