httpd: httpd: HTTP response smuggling via crafted Transfer-Encoding response in mod_proxy_uwsgi
Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') response smuggling vulnerability in Apache HTTP Server via mod_proxy_uwsgi and a crafted uwsgi response with Transfer-Encoding.
This issue affects Apache HTTP Server: from 2.4.30 through 2.4.68.
A flaw was found in the mod_proxy_uwsgi module of Apache HTTP Server. This issue allows HTTP response smuggling when the server processes a crafted uWSGI response containing a Transfer-Encoding header. A remote attacker can exploit this vulnerability to desynchronize HTTP communications, potentially leading to response tampering or cache poisoning for other users.
Mitigation: If uWSGI proxy functionality is not required,
No detection rules found.
