Vulnerable Component: BIG-IP ASM, APM,LTM

Affected Versions:
16.0.0 - 16.0.1.0
15.1.0 - 15.1.1
14.1.0 - 14.1.3.0

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

A remote attacker may be able to cause the BIG-IP system to produce a core file, disrupting the flow of traffic and causing a failover to a standby system, if configured. Additionally, in rare circumstances, running the tmsh show conn command may trigger this vulnerability.
