2023-10-27 15:11

A critical vulnerability in the F5 BIG-IP configuration utility, tracked as CVE-2023-46747, allows an attacker with remote access to the configuration utility to perform unauthenticated remote code execution.

"This vulnerability may allow an unauthenticated attacker with network access to the BIG-IP system through the management port and/or self IP addresses to execute arbitrary system commands," reads F5's security bulletin.

As F5 BIG-IP devices are used by governments, Fortune 500 firms, banks, service providers, and major consumer brands, it is strongly advised to apply any available fixes or mitigations to prevent the exploitation of these devices.

As shown in the past, the F5 BIG-IP TMUI has been exposed in the past, allowing attackers to exploit vulnerabilities to wipe devices and gain initial access to networks.
