The vulnerability of the CurlAsyncHTTPClient component in the asynchronous networking library Tornado allows a hacker to execute arbitrary code.

The vulnerability of the CurlAsyncHTTPClient component in the Tornado asynchronous networking library is related to the lack of measures taken to neutralize CRLF sequences. Exploiting this vulnerability allows a remote attacker to execute arbitrary code by sending specially crafted HTTP requests ...

ROS-20241112-04

Vulnerability of http requests of CurlAsyncHTTPClient component of Tornado asynchronous network library is related to improper neutralization of CRLF sequences. Exploitation of the vulnerability could allow an attacker acting remotely to inject arbitrary headers into a request or cause an...

Request Smuggling

tornado is vulnerable to Request Smuggling. This vulnerability is due to mishandling multiple Transfer-Encoding: chunked headers, which allows for request smuggling attacks when deployed behind a proxy server that emits such requests...

CRLF Injection

tornado is vulnerable to CRLF Injection. The vulnerability is due to improper CR/LF checks allowing for the inclusion of attacker-controlled header values in requests, which allows arbitrary headers or requests to be sent to a specified server...

Tornado has a CRLF injection in CurlAsyncHTTPClient headers

Summary Tornado’s curlhttpclient.CurlAsyncHTTPClient class is vulnerable to CRLF carriage return/line feed injection in the request headers. Details When an HTTP request is sent using CurlAsyncHTTPClient, Tornado does not reject carriage return \r or line feed \n characters in the request headers...

GHSA-753J-MPMX-QQ6G Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') in tornado

Summary When Tornado receives a request with two Transfer-Encoding: chunked headers, it ignores them both. This enables request smuggling when Tornado is deployed behind a proxy server that emits such requests. Pound does this. PoC 0. Install Tornado. 1. Start a simple Tornado server that echoes...
