Threat actors have started massively exploiting the critical vulnerability tracked as CVE-2022-1388, which affects multiple versions of all F5 BIG-IP modules, to drop malicious payloads.
F5 last week released patches for the security issue, which affects the BIG-IP iControl REST authentication component.
The company warned that the vulnerability enables an unauthenticated attacker on the BIG-IP system to run "Arbitrary system commands, create or delete files, or disable services."
At the moment, there are thousands of BIG-IP systems exposed on the internet, so attackers can leverage the exploit remotely to breach the corporate network.
Yesterday, multiple security researchers announced that they had created working exploits and warned administrators to install the latest updates immediately.
The vulnerability is so easy to exploit that some security researchers believe that it did not end up in the products by accident, especially considering that the vulnerable endpoint is named 'bash', a popular Linux shell.
