Security Advisory Recommended Actions If you are running a version listed in the Versions known to be vulnerable column, you can eliminate this vulnerability by upgrading to a version listed in the Fixes introduced in column. If the table lists only an older version than what you are currently running, or does not list a non-vulnerable version, then no upgrade candidate currently exists. Note: For details about how Security Advisory articles are versioned, and what versions are listed in the table, refer to K51812227: Understanding Security Advisory versioning. To determine the necessary upgrade path for your BIG-IQ system, you should understand the BIG-IQ product offering name changes. For more information, refer to K21232150: Considerations for upgrading BIG-IQ or F5 iWorkflow systems . Mitigation To mitigate this vulnerability, you should permit management access to F5 products only over a secure network and restrict access for affected systems to trusted users. For more information, refer to K13309: Restricting access to the Configuration utility by source IP address (11.x - 13.x) and K13092: Overview of securing access to the BIG-IP system. - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
