The following analytic detects attempts to exploit the CVE-2023-46747 vulnerability, an authentication bypass flaw in F5 BIG-IP's Configuration utility (TMUI). It identifies this activity by monitoring for specific URI paths such as "*/mgmt/tm/auth/user/*" with the PATCH method and a 200 status code. This behavior is significant for a SOC as it indicates potential unauthorized access attempts, leading to remote code execution. If confirmed malicious, an attacker could gain unauthorized access, execute arbitrary code, steal data, disrupt systems, or conduct further malicious activities within the network.
Detects exploitation activity of CVE-2023-46747, an unauthenticated remote code execution vulnerability in F5 BIG-IP. The rule looks for specific POST requests to '/mgmt/tm/util/bash' containing keywords related to form submission and user creation within the F5 BIG-IP Traffic Management User Interface (TMUI).
Detects exploitation activity targeting CVE-2023-46747, an unauthenticated remote code execution vulnerability in F5 BIG-IP. The rule specifically looks for POST requests to '/mgmt/tm/util/bash' containing hex-encoded or plain text strings related to '/tmui/Control/form' and 'form_page=%2ftmui%2fsystem%2fuser%2fcreate.jsp', which are indicators of the exploit attempting to create a new user.
