Security Bulletin: TLS padding vulnerability affects Sterling Connect:Direct for UNIX (CVE-2014-8730)
Transport Layer Security (TLS) padding vulnerability via a POODLE (Padding Oracle On Downgraded Legacy Encryption) like attack affects Sterling Connect:Direct for UNIX.
Product could allow a remote attacker to obtain sensitive information, caused by the failure to check the contents of the padding bytes when using CBC cipher suites of some TLS implementations. A remote user with the ability to conduct a man-in-the-middle attack could exploit this vulnerability via a POODLE (Padding Oracle On Downgraded Legacy Encryption) like attack to decrypt sensitive information and calculate the plaintext of secure connections.
