CVE-2024-6827
HighSummary
Wersja 21.2.0 Gunicorn nieprawidłowo waliduje wartość nagłówka 'Transfer-Encoding' zgodnie z normami RFC, co prowadzi do domyślnej metody 'Content-Length'. To sprawia, że jest podatny na ataki typu TE.CL, co może prowadzić do wielu poważnych zagrożeń.
Risk Assessment
Podatność ta może skutkować zanieczyszczeniem pamięci podręcznej, ujawnieniem danych, manipulacją sesjami, a także innymi atakami, które mogą narazić integralność danych i bezpieczeństwo organizacji.
Recommendation
Zaleca się aktualizację Gunicorn do najnowszej wersji, która poprawia walidację nagłówka 'Transfer-Encoding', aby zminimalizować ryzyko związane z tą podatnością.

Original NVD description (English source)
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.
