F5: Security Vulnerabilities
DHCP can add routes to a client’s routing table via the classless static route option (121). VPN-based security solutions that rely on routes to redirect traffic can be forced to leak traffic over the physical interface. An attacker on the same local network can read, disrupt, or possibly modify network traffic that was expected to be protected by the VPN.

Undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate. For the Application Visibility and Reporting module, this may occur when the HTTP Analytics profile with URLs enabled under Collected Entities is configured on a virtual server and the DB variables avr.IncludeServerInURI or avr.CollectOnlyHostnameFromURI are enabled. For BIG-IP Advanced WAF and ASM, this may occur when either a DoS or Bot Defense profile is configured on a virtual server and the DB variables avr.IncludeServerInURI or avr.CollectOnlyHostnameFromURI are enabled.
Note: The DB variables avr.IncludeServerInURI and avr.CollectOnlyHostnameFromURI are not enabled by default. For more information about the HTTP Analytics profile and the Collect URLs setting, refer to K30875743: Create a new Analytics profile and attach it to your virtual servers https://my.f5.com/manage/s/article/K30875743 .
