CVE-2022-31043
Fix failure to strip Authorization header on HTTP downgrade in Guzzle
En resumen
Guzzle, un popular cliente HTTP de PHP, estaba filtrando headers de Authorization sensibles al seguir automáticamente redirecciones de conexiones HTTPS seguras a conexiones HTTP inseguras. Esto exponía credenciales de acceso y tokens de autenticación a posibles atacantes.
Detalle técnico
Cuando Guzzle sigue una redirección de HTTPS a HTTP, el header Authorization no se elimina antes de la degradación, violando el principio de mismo origen aplicado a cambios de host. Un atacante controlando el destino de redirección puede interceptar credenciales en texto plano mediante sniffing de red. Requiere que la aplicación siga redirecionamientos automáticamente, que es el comportamiento predeterminado.
Resumen generado y traducido por IA a partir de la descripción oficial.
Guzzle is an open source PHP HTTP client. In affected versions `Authorization` headers on requests are sensitive information. On making a request using the `https` scheme to a server which responds with a redirect to a URI with the `http` scheme, we should not forward the `Authorization` header on. This is much the same as to how we don't forward on the header if the host changes. Prior to this fix, `https` to `http` downgrades did not result in the `Authorization` header being removed, only changes to the host. Affected Guzzle 7 users should upgrade to Guzzle 7.4.4 as soon as possible. Affected users using any earlier series of Guzzle should upgrade to Guzzle 6.5.7 or 7.4.4. Users unable to upgrade may consider an alternative approach which would be to use their own redirect middleware. Alternately users may simply disable redirects all together if redirects are not expected or required.
