Threat Response: UPDATE – Remote Code Execution vulnerability in F5 BIG-IP Systems



On July 6th 2020 we sent out a Threat Response regarding a number of vulnerabilities in F5 BIG-IP systems [1]. We advised you to update the concerning systems as soon as possible, and if this was not feasible, to apply mitigation steps.

It has become clear that the mitigation steps originally recommended by F5 for the most critical vulnerability – CVE-2020-5902 – are not sufficient. It is possible to bypass them [2]. F5 updated the mitigation steps, see [3]. However, F5 strongly urges to apply the update. Northwave concurs with this advice. Updating removes the vulnerability entirely. We have seen scanning traffic for this vulnerability on the internet.
