Remediation/Fixes
Apply the following fixes to upgrade the Java Runtime Environment.
| Product | VRMF | Fix | How to acquire fix |
| Sterling Secure Proxy | 3.4.2.0 | APAR IT07375 | Fix Central - 3.4.2.0 |
| Sterling Secure Proxy | 3.4.1.8 | APAR IT07375 | Fix Central - 3.4.1.8 |
| Sterling Secure Proxy | 3.4.0.6 | APAR IT07375 | Fix Central - 3.4.0.6 |
| Sterling Secure Proxy | 3.3.1.23 | iFix 6 | Contact Support and request the latest 3.3.1.23 build fix package to be published for you on the ECuRep server. |
| Sterling External Authentication Server | 2.4.2.0 | APAR IT07375 | Fix Central - 2.4.2.0 |
| Sterling External Authentication Server | 2.4.1.8 | APAR IT07375 | Fix Central - 2.4.1.8 |
| Sterling External Authentication Server | 2.4.0.4 | APAR IT07375 | Fix Central - 2.4.0.4 |
| Sterling External Authentication Server | 2.3.1.11 | iFix 5 | Contact Support and request the latest 2.3.1.11 build fix package to be published for you on the ECuRep server. |
The APAR fixes above include an upgrade of the Java Runtime Environment only, with instructions on how to install it in the Customer's environment. This brings the Java Runtime Environment to the Java 1.7 SR8 fix level. Alternately, the Customer may check the fixlist of the latest iFix cumulative maintenance package on Fix Central to see if it includes this level of Java. If not, the Customer may contact Support to request that the latest build with this Java Runtime Environment be placed on the ECuRep server.
With this fix, Sterling Secure Proxy 3.4.2.0 and all versions of Sterling External Authentication Server will only allow TLS sessions by default and will reject SSLv3 sessions. Sterling Secure Proxy releases prior to 3.4.2.0 continue to allow SSLv3 sessions if SSL is coded in the netmap security tab.
Workarounds and Mitigations
IBM recommends using TLS. However, if the SSLv3 protocol is required until trading partners can switch to TLS, then the follow the workaround instructions below:
- For UNIX/Linux, add the -Dcom.ibm.jsse2.disableSSLv3=false property to the Java startup line(s) in the bin/startEngine.sh script;
- For Windows, add the property to the " lax.nl.java.option.additional=" line in the bin\SSPengine$.lax file.
These instructions are in addition to the workarounds listed here Security Bulletin: Vulnerability in SSLv3 affects IBM Sterling Secure Proxy (CVE-2014-3566).
IBM recommends that you review your entire environment to identify areas that enable the SSLv3 protocol and take appropriate mitigation and remediation actions.
