Description

The parse function in llhttp < 2.1.4 and < 6.0.6. ignores chunk extensions when parsing the body of chunked requests. This leads to HTTP Request Smuggling (HRS) under certain conditions. An HTTP Request Smuggling (HRS) vulnerability was found in the llhttp library, used by Node.JS. During the parsing of chunked messages, the chunk size parameter was not validated properly. In situations where HTTP conversations are being proxied (such as proxy, reverse-proxy, load-balancer), an attacker can use this flaw to inject arbitrary messages through the proxy. The highest threat from this vulnerability is to confidentiality and integrity.
