Transport Layer Security (TLS) padding vulnerability via a POODLE (Padding Oracle On Downgraded Legacy Encryption) like attack affects TXSeries for Multiplatforms.
CVE-ID: CVE-2014-8730
DESCRIPTION:
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.

TXSeries for Multiplatforms provides an optional configurable capability to enable SSL for its IPIC communication protocol.
TXSeries for Multiplatforms V7.1
If you are on TXSeries for Multiplatforms V7.1, you need to upgrade to Fixpack 4 or higher. Lower fix pack levels do not address this TLS vulnerability.
1. Stop the TXSeries region.
2. If you have not configured your region to use GSKit version 8.x, set the below variable in the regionโs environment file. CICS_GSKIT_VERSION=8
If your region is already configured with GSKit version 8.x then go to step 3.
(By Default TXSeries 7.1 support GSKit version 7.x. Refer to the TXSeries infocenter for further configuration details.)
3. Set the below environment variable in the regionโs environment file.
GSK_STRICTCHECK_CBCPADBYTES=GSK_TRUE
4. Restart the TXSeries region.
TXSeries for Multiplatforms V8.1
1. Stop the TXSeries region.
2. Set the below environment variable in the regions environment file
GSK_STRICTCHECK_CBCPADBYTES=GSK_TRUE
3. Restart the TXSeries region.
