TornadoWebServer Inconsistent Interpretation of HTTP Requests (HTTP Request/Response Smuggling) V - CVE-2024-14029
Tornado before 6.4.1 ignores duplicate Transfer-Encoding: chunked headers treating requests as having no message body and parsing the chunked body as a subsequent request. Attackers can exploit this inconsistency when Tornado is deployed behind proxies to perform HTTP request smuggling enabling access control bypass cache poisoning or connection desynchronization.
