Issue

  • "Obsolete CBC Ciphers" warning message can appear during a security revision or in certain browsers.

Environment

  • Liferay DXP.

Resolution

  1. The message points to a vulnerability related to the available cipher protocols for HTTP transport.
  2. This communication is always ciphered by external elements to Liferay DXP (depending on the project nature can be the load balancer, the application server, the web server, etc.).
  3. Review which of your infrastructure elements are offering this cipher and update them accordingly (reviewing SSL certificates, additional configuration,...)
