Almost 10 days after application security company F5 Networks released patches for critical vulnerabilities in its BIG-IP and BIG-IQ products, adversaries have begun opportunistically mass scanning and targeting exposed and unpatched networking devices to break into enterprise networks.
News of in the wild exploitation comes on the heels of a proof-of-concept exploit code that surfaced online earlier this week by reverse-engineering the Java software patch in BIG-IP. The mass scans are said to have spiked since March 18.
The flaws affect BIG-IP versions 11.6 or 12.x and newer, with a critical remote code execution (CVE-2021-22986) also impacting BIG-IQ versions 6.x and 7.x. CVE-2021-22986 (CVSS score: 9.8) is notable for the fact that it’s an unauthenticated, remote command execution vulnerability affecting the iControl REST interface, allowing an attacker to execute arbitrary system commands, create or delete files, and disable services without the need for any authentication.
Successful exploitation of these vulnerabilities could lead to a full compromise of susceptible systems, including the possibility of remote code execution as well as trigger a buffer overflow, leading…
