Description

The vulnerability allows a remote attacker to preform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests in io.netty:netty-codec-http2 in Netty, if the request only uses a single Http2HeaderFrame with the endStream set to to true. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.

Note, the vulnerability exists due to incomplete fix for #VU51837 (CVE-2021-21409).
