Summary
The remote load balancer suffers from an information disclosure vulnerability.
Insight
Insight
The remote host appears to be a F5 BigIP load balancer which encodes within a cookie the IP address of the actual web server it is acting on behalf of. Additionally, information after 'BIGipServer' is configured by the user and may be the logical name of the device. These values may disclose sensitive information, such as internal IP addresses and names.
