Workarounds and Mitigations
The fix removes DES-based ciphersuites from the set supported by default by the DataPower management interface. To remove these ciphersuites manually, perform the following steps:
- Create a new SSL server profile in default domain.
- Remove the 5 3DES ciphers listed at the bottom of default cipher list (vis. ECDHE_RSA_WITH_3DES_EDE_CBC_SHA, ECDHE_ECDSA_WITH_3DES_EDE_CBC_SHA, DHE_DSS_WITH_3DES_EDE_CBC_SHA, DHE_RSA_WITH_3DES_EDE_CBC_SHA, RSA_WITH_3DES_EDE_CBC_SHA).
- Create new/assign existing identification credentials for this server profile.
- Save the new SSL server profile.
- While still in the default domain, navigate to Network->Management->Web Management Service.
- In the Advanced tab, ensure Custom SSL server type is “Server Profile”.
- Set custom SSL server profile property to the newly created SSL server profile in step #4.
