CVSS: 8.1EPSS: 0%CPEs: 2EXPL: 0CVE-2021-21299 – Multiple Transfer-Encoding headers misinterprets request payload
https://notcve.org/view.php?id=CVE-2021-21299
hyper is an open-source HTTP library for Rust (crates.io). In hyper from version 0.12.0 and before versions 0.13.10 and 0.14.3 there is a vulnerability that can enable a request smuggling attack. The HTTP server code had a flaw that incorrectly understands some requests with multiple transfer-encoding headers to have a chunked payload, when it should have been rejected as illegal. This combined with an upstream HTTP proxy that understands the request payload boundary differently can result in "request smuggling" or "desync attacks". To determine if vulnerable, all these things must be true: 1) Using hyper as an HTTP server (the client is not affected), 2) Using HTTP/1.1 (HTTP/2 does not use transfer-encoding), 3) Using a vulnerable HTTP proxy upstream to hyper. • https://crates.io/crates/hyper https://github.com/hyperium/hyper/commit/8f93123efef5c1361086688fe4f34c83c89cec02 https://github.com/hyperium/hyper/security/advisories/GHSA-6hfq-h8hq-87mf https://portswigger.net/research/http-desync-attacks-request-smuggling-reborn https://rustsec.org/advisories/RUSTSEC-2021-0020.html • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

A HTTP/2 implementation built using any version of the Python HPACK library between v1.0.0 and v2.2.0 could be targeted for a denial of service attack, specifically a so-called "HPACK Bomb" attack. This attack occurs when an attacker inserts a header field that is exactly the size of the HPACK dynamic header table into the dynamic header table. The attacker can then send a header block that is simply repeated requests to expand that field in the dynamic table. This can lead to a gigantic compression ratio of 4,096 or better, meaning that 16kB of data can decompress to 64MB of data on the target machine. Una implementación de HTTP/2 construida usando cualquier versión de la librería de Python HPACK entre las versiones v1.0.0 y v2.2.0 podría ser atacada por un ataque de denegación de servicio, especialmente un ataque llamado "HPACK Bomb". • http://www.securityfocus.com/bid/92315 https://python-hyper.org/hpack/en/latest/security/CVE-2016-6581.html • CWE-399: Resource Management Errors •
