What does this mean?
The iControl REST component can be bypassed for authentication, which allows commands to run on the device with the highest privileges.Source: secpod.com
Am I affected, and how do I check?
The listed ranges are BIG-IP 16.1.0 to 16.1.2 and 15.1.0 to 15.1.5, plus older 14.1, 13.1, 12.1 and 11.6 releases up to their listed last affected versions. Compare the BIG-IP version reported by the device against these ranges.Source: secpod.com
What should I do about it?
Upgrade to 16.1.2.2 on the 16.x branch, 15.1.5.1 on 15.x, 14.1.4.6 on 14.x, or 13.1.5 on 13.x. On 12.1 and 11.6, the listed last affected versions are 12.1.6 and 11.6.5, so move to a release outside those ranges.Source: secpod.com
Is it being exploited?
Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2022-05-10, which means it has evidence of attacks. No public exploit code is tracked.Source: cisa.gov, cve.now feed data
