Descriptions

The Apache2 component in PHP before 5.6.38, 7.0.x before 7.0.32, 7.1.x before 7.1.22, and 7.2.x before 7.2.10 allows XSS via the body of a "Transfer-Encoding: chunked" request, because the bucket brigade is mishandled in the php_handler function in sapi/apache2handler/sapi_apache2.c.

El componente Apache2 en PHP en versiones anteriores a la 5.6.38, versiones 7.0.x anteriores a la 7.0.32, versiones 7.1.x anteriores a la 7.1.22 y versiones 7.2.x anteriores a la 7.2.10 permite Cross-Site Scripting (XSS) mediante el cuerpo de una petición "Transfer-Encoding: chunked". Esto se debe a que bucket brigade se gestiona de manera incorrecta en la función php_handler en sapi apache2handler sapi_apache2.c.

A cross-site scripting (XSS) vulnerability in Apache2 component of PHP was found. When using 'Transfer-Encoding: chunked', the request allows remote attackers to potentially run a malicious script in a victim's browser. This vulnerability can be exploited only by producing malformed requests and it's believed it's unlikely to be used in practical cross-site scripting attack.
