On Thursday, cybersecurity firm NCC Group said that it detected successful in the wild exploitation of a recently patched critical vulnerability in F5 BIG-IP and BIG-IQ networking devices.
The security vulnerability these attackers attempt to exploit is an unauthenticated remote command execution tracked as CVE-2021-22986, and it affects most F5 BIG-IP and BIG-IQ software versions.
A similarly critical RCE vulnerability with a maximum 10/10 severity rating tracked as CVE-2020-5902 in F5 BIG-IP ADC appliances was also heavily exploited last year after being patched in July 2020.
Organizations are advised to patch their F5 BIG-IP devices as soon as possible to defend against future attacks.
"We strongly encourage all customers to update their BIG-IP and BIG-IQ systems to a fixed version as soon as possible," F5 said after releasing security updates to patch CVE-2021-22986 and three other critical security flaws affecting its products.
F5 provides info on upgrading BIG-IP appliances with details on multiple upgrade scenarios in this BIG-IP upgrade guide.
