Hackers are scanning the web for exposed and unpatched networking equipment that slide below F5 Networks’ Major-IP spouse and children of hardware and application goods to obtain entry to vulnerable company networks.
A fortnight in the past, F5 warned consumers about 7 distant code execution vulnerabilities in its Significant-IP goods, like four that had been rated ‘critical’. Though fixes were launched, researchers with NCC Group have now located proof that cyber criminals have deployed a entire chain exploitation against a person of these flaws, tracked as CVE-2021-22986.

The remote code execution flaw, rated 9.8 on the CVSS danger severity scale, lies in the iControl Rest interface for the Major-IP spouse and children, and also has an effect on the firm’s Significant-IQ items. Attackers are exploiting the vulnerability to execute arbitrary commands, create and delete documents as well as disable solutions without the need of authentication.
This was the 2nd most intense bug that F5 patched following the 9.9-rated CVE-2021-22987, which manifested in the website traffic administration person interface (TMUI) when running Huge-IP in Application Method.
“We strongly propose that all consumers update their Major-IP and Big-IQ deployments to a fastened edition as before long as possible – this is the only way to thoroughly deal with the vulnerabilities,” said F5 Networks’ SVP and GM for the Software Shipping and delivery Controller (ADC) business enterprise unit, Kara Spraque.
“If you are not able to update your devices quickly, we advise you to implement any more mitigation tips thorough in the security advisories when building a plan to complete the updates.”
This is the 16th actively-exploited vulnerability discovered in 2021, becoming a member of an expanding record that involves a few vulnerabilities in Google Chrome, as properly as 4 Microsoft Exchange Server flaws that devastated a string of companies.
The discovery of this entire chain exploitation follows several proofs-of-principle for exploitation techniques against the F5 Networks vulnerability.
More than the final few times, NCC Team has detected a rise in scanning exercise, and numerous exploitation tries towards honeypot infrastructure that scientists experienced established up to monitor destructive exercise. This understanding has led them to feel that a public exploit is probably to be in the public area really soon.
Scientists with Unit 42, in the meantime, have viewed proof that a variant of the Mirai botnet has tried to exploit CVE-2021-22986, as nicely as CVE-2020-28188, a remote code execution flaw in the TerraMaster running procedure for storage appliances. This latter was uncovered last calendar year.
