Описание
Gunicorn version 21.2.0 does not properly validate the value of the 'Transfer-Encoding' header as specified in the RFC standards, which leads to the default fallback method of 'Content-Length,' making it vulnerable to TE.CL request smuggling. This vulnerability can lead to cache poisoning, data exposure, session manipulation, SSRF, XSS, DoS, data integrity compromise, security bypass, information leakage, and business logic abuse.
A flaw was found in Gunicorn. This vulnerability allows request smuggling, leading to cache poisoning, data exposure, session manipulation, Server-side request forgery (SSRF), Cross-site scripting (XSS), denial of service (DoS), data integrity compromise, security bypass, and information leakage via improper validation of the 'Transfer-Encoding' header.
Меры по смягчению последствий
Red Hat Product Security currently does not have a recommended mitigation at this time.
