Name of the Vulnerable Software and Affected Versions F5 BIG-IP versions 13.1.0 through 17.1.0

Description F5 BIG-IP devices are affected by a critical vulnerability that allows unauthenticated attackers with network access to the management port or self IP addresses to execute arbitrary system commands. This is due to a flaw in the configuration utility that bypasses authentication checks. The vulnerability is actively exploited in the wild, with reports of initial access brokers leveraging it, and has been linked to ransomware campaigns. The vulnerability is related to request smuggling and the Apache JServ Protocol (AJP). The issue impacts all versions of BIG-IP and is limited to the control plane.

Recommendations Apply the applicable engineering hotfix for all affected versions. Restrict internet access to the BIG-IP management interface. Consider temporarily disabling the vulnerable configuration utility until a patch can be applied.
