QID Detection Logic(Authenticated):
This QID checks for the vulnerable versions of F5 BIG-IP devices using the tmsh command.

Local users with administrative access to the BIG-IP Advanced Shell (bash) may be able to perform a resource-consumption denial-of-service (DoS) attack. This attack can only be exploited by uncompressing a ZIP file using the zip or unzip utility from the command line or by a user-generated script. No F5 scripts or utilities call these programs to unpack a ZIP archive.
