Summary

A vulnerability exists in certain versions of F5 Networks' BIG-IP and BIG-IQ products, where a user with tmsh access can trigger a denial of service condition. By continuously executing the 'edit cli preference' command and saving changes to alternate filenames, the user can exhaust the available storage on the /var partition. This can lead to significant system performance degradation and unavailability, impacting network operations.
