Descriptions

Faulty input validation in the core of Apache allows malicious or exploitable backend/content generators to split HTTP responses.

This issue affects Apache HTTP Server: through 2.4.58.

La validación de entrada defectuosa en el núcleo de Apache permite que generadores de contenido/backend maliciosos o explotables dividan las respuestas HTTP. Este problema afecta al servidor HTTP Apache: hasta 2.4.58.

A flaw was found in httpd. The response headers are not sanitized before an HTTP response is sent when a malicious backend can insert a Content-Type, Content-Encoding, or some other headers, resulting in an HTTP response splitting.
