AI-suggested
A patch is available in Tornado version 2.2.0_1 that addresses this vulnerability. Users should upgrade to version 2.2.0_1 or later to mitigate the risk. Until patched, avoid using CurlAsyncHTTPClient with untrusted header data or sanitize header values to remove CRLF characters before sending requests.
Description
Tornado's CurlAsyncHTTPClient class allows injection of carriage return and line feed (CRLF) characters in HTTP request headers, enabling attackers to inject arbitrary headers or craft additional HTTP requests. This occurs because Tornado does not validate header values before passing them to libcurl, which does not filter control characters. Applications using Tornado to send HTTP requests with untrusted header data are vulnerable to this issue, which can facilitate server-side request forgery (SSRF) exploitation. A fix is available in Tornado version 2.2.0_1.
