Cybersecurity researchers today issued a security advisory warning enterprises and governments across the globe to immediately patch a highly-critical remote code execution vulnerability affecting F5’s BIG-IP networking devices running application security servers.
The vulnerability, assigned CVE-2020-5902 and rated as critical with a CVSS score of 10 out of 10, could let remote attackers take complete control of the targeted systems, eventually gaining surveillance over the application data they manage.
According to Mikhail Klyuchnikov, a security researcher at Positive Technologies who discovered the flaw and reported it to F5 Networks, the issue resides in a configuration utility called Traffic Management User Interface (TMUI) for BIG-IP application delivery controller (ADC).
BIG-IP ADC is being used by large enterprises, data centers, and cloud computing environments, allowing them to implement application acceleration, load balancing, rate shaping, SSL offloading, and web application firewall.
