# Undisclosed requests may bypass configuration utility authentication, allowing an attacker with network access to…

F5 BIG-IP's Configuration Utility has an authentication bypass that lets an unauthenticated attacker reach the management interface through alternate request paths. The attacker can then execute system commands on the BIG-IP appliance.

_Summary, check and fix written by a model from the sources; labelled as such._

## Fix

Apply the mitigation or fix from the F5 vendor advisory, or discontinue use of the product if no mitigation is available (per CISA required action).

## From the sources

F5 BIG-IP Configuration utility contains an authentication bypass using an alternate path or channel vulnerability due to undisclosed requests that may allow an unauthenticated attacker with network access to the BIG-IP system through the management port and/or self IP addresses to execute system commands. This vulnerability can be used in conjunction with CVE-2023-46748.

CISA required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
