what is HTTP smuggling and how it works

Question

Accepted Answer

HTTP smuggling is a technique used to bypass security measures by manipulating the way HTTP requests are interpreted by intermediaries.

HTTP smuggling involves sending specially crafted HTTP requests that can be interpreted differently by different components in the communication chain
It can be used to bypass firewalls, web application firewalls, and other security measures
One example of HTTP smuggling is HTTP request smuggling, where an attacker sends a request that can be interpreted as two separate requests by different components
Another example is HTTP response smuggling, where an attacker manipulates the way a response is interpreted by a proxy or other intermediary
HTTP smuggling attacks can be difficult to detect and mitigate, as they rely on exploiting inconsistencies in the way different components interpret HTTP requests and responses
