RedSeal Cyber Threat Series
F5 has released patches for several BIG-IP and BIG-IQ critical vulnerabilities. CVE-2021-22986 is the most critical since it allows unauthenticated attackers with network access to use the iControl REST interface, via the BIG-IP management interface and self IP addresses, to execute system commands that could lead to complete system compromise. This vulnerability can only be exploited through the control plane and cannot be exploited through the data plane.
RedSeal customers should:
- Run a custom best practice check to receive a list of vulnerable devices
- Create and run daily reports until all affected systems are patched.
