IBM recommends that you review your entire environment to identify areas that enable the SSLv3 protocol and take appropriate mitigation and remediation actions. The most immediate mitigation action that can be taken is disabling SSLv3. You should verify disabling SSLv3 does not cause any compatibility issues
.

Workarounds and Mitigations

Reconfigure to disable SSLv3 and select TLS 1.0 or higher where possible. If using NIST strict mode, TLS 1.2 is already enabled.

The following table provides instructions on how to reconfigure secure connection settings that apply to both Sterling B2B Integrator 5.2 and 5.1, except where noted. After making the necessary changes, you will need to stop and restart IBM Sterling B2B Integrator in order for these changes to take affect.

If you use:Then do this:
  • Dashboard
  • Map Editor
  • All other product UIs
Disable SSLv3 in your internet browser. See your internet browser help for instructions on how to do this.
  • Communications adapters (FTP Client, FTP Server, HTTP Client, HTTP Server etc.)
  • Sterling Control Center Monitor
  • SWIFTNet Server adapter

    Note that these instructions help to disable SSLv3 for HTTP Server Adapter in fixpack 5103 onwards and 5.2.4.1 onwards. Those who are on older fixpacks need to upgrade to latest versions to apply the fix to HTTP Server Adapter.
  1. Navigate to the installation directory
  2. Navigate to the properties directory.
  3. Edit the customer_overrides.properties file.
  4. Add security.SSLHelloProtocol=TLS1-TLS1.2 to the end of the file.
    Note: If you already have security.SSLHelloProtocolForFIPS=TLS1-ONLY in customer_overrides.properties, keep this default value.
  5. Save and close the file.
  • JMS1.1 Acquire Connection and Session service
  • JMS1.1 Async Receive adapter
Disable SSLv3 in your JMS server. See your JMS server documentation for information on how to do this.
  • SMTP Send adapter
  • B2B Mail Client adapter
Disable SSLv3 in your mail server. See your mail server documentation for information on how to do this.
  • WebSphere MQ Suite Async Receive adapter
  • WebSphere MQ adapter
  • WebSphere MQ File Transfer Edition Agent adapter (Sterling B2B Integrator 5.2 only)
  • WebSphere MQ File Transfer Edition Create Transfer service (Sterling B2B Integrator 5.2 only)
  • MEIG Messaging Config adapter (Applies only to Multi-Enterprise Integration Gateway users of Sterling B2B Integrator 5.2.4.2)
Disable SSLv3 in your MQ server. See your WebSphere MQ server documentation for information on how to do this.

When using these adapters, only use TLS ciphers. For more information, see the WSMQ security bulletin:
Security Bulletin: Vulnerability in SSLv3 affects IBM WebSphere MQ, IBM WebSphere MQ Internet Pass-Thru and IBM Mobile Messaging and M2M Client Pack (CVE-2014-3566)
  • Connect:Direct Requester Adapter
  • Connect:Direct Server Adapter
Update all existing configurations of these services and adapters to use TLS instead of SSL:
  1. Navigate to Deployment > Services > Configuration.
  2. Under List, select the service type you want to update and click Go!
  3. Click edit next to the service configuration you want to update.
  4. Click Next until you get to the Encryption screen.
  5. On the Encryption screen, under Encryption using Secure+, select Enabled and click Next.
  6. Complete the Secure+ Configuration screen as required, but in particular ensure that you select TLS under SSL or TLS for Sterling B2B Integrator version before 5.2.4.2 and select TLS 1.0 or TLS 1.2 under Security Protocol for version 5.2.4.2 and click Next.
  7. Click Finish.
  • OdetteFTP adapter (Sterling B2B Integrator 5.2.4.2 only)
  1. Navigate to the installation directory.
  2. Navigate to the properties directory.
  3. View the OdetteFTP.properties file.
  4. If you already have OFTP.Global.HelloProtocol=TLS1-TLS1.2 keep this default value.
  5. If you do not have the default value, navigate to the customer_overrides.properties
  6. Edit the file and add
    OdetteFTP.OFTP.Global.HelloProtocol=TLS1-TLS1.2
  7. Save and close the file.
