HTTP exploits involve using the Web server application to perform malicious activities. These attacks are very common and are growing in popularity because firewalls typically block most traffi c from the Internet to keep it away from corporate servers. However, HTTP traffic, used for Web browsing, is almost always allowed to pass through fi rewalls unhindered.Thus, attackers have a direct line to the Web server. If they can coerce the Web server into performing malicious activities, they can access resources that would otherwise be unavailable.
