Description
This security bulletin contains information about 1 security vulnerability.
1) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2022-45059)
The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers. Among the headers that can be filtered this way are both Content-Length</code> and <code>Host, making it possible for an attacker to both break the HTTP/1 protocol framing, and bypass request to host routing in VCL.
