Security Bulletin: IBM Sterling Connect:Direct for OpenVMS. Unencrypted data transfers can occur even when SSL encryption is specified in the security configuration. (CVE-2013-4035)
Unencrypted data transfers can occur even when SSL encryption is specified in the security configuration.
When Connect:Direct for OpenVMS is the server in a TCP/IP session, and the
client requests an unencrypted session, C:D OpenVMS will allow the unencrypted
session to proceed even if it is configured for SSL encryption with the client. The
correct response is to reject the requested unencrypted session.
