Recommended Action

If the previous table lists a version in the Versions known to be not vulnerable column, you can eliminate this vulnerability by upgrading to the listed version. If the listed version is older than the version you are currently running, or if the table does not list any version in the column, then no upgrade candidate currently exists.

F5 is responding to this vulnerability as determined by the parameters defined in SOL4602: Overview of the F5 security vulnerability response policy.

To mitigate this vulnerability, you should consider the following recommendations:

• Limit the Configuration utility access to a trusted management network.

• Ensure that the SSL profiles are configured to use SSL ciphers from the NATIVE SSL stack. Starting in BIG-IP 10.2.3 and 11.0.0, commonly used cipher strings (excluding the COMPAT string) only include ciphers from the NATIVE SSL stack, and do not include SSL ciphers from the COMPAT SSL stack. For example, the following cipher strings only include ciphers from the NATIVE SSL stack:

  • DEFAULT
  • ALL
  • LOW
  • MEDIUM
  • HIGH
  • EXP
