Descriptions

The OpenID Connect server implementation for MITREid Connect through 1.3.3 contains a Server Side Request Forgery (SSRF) vulnerability. The vulnerability arises due to unsafe usage of the logo_uri parameter in the Dynamic Client Registration request. An unauthenticated attacker can make a HTTP request from the vulnerable server to any address in the internal network and obtain its response (which might, for example, have a JavaScript payload for resultant XSS). The issue can be exploited to bypass network boundaries, obtain sensitive data, or attack other hosts in the internal network.

La implementación del servidor OpenID Connect para MITREid Connect versiones hasta 1.3.3, contiene una vulnerabilidad de Server Side Request Forgery (SSRF). La vulnerabilidad surge debido al uso no seguro del parámetro logo_uri en la petición de registro de cliente dinámico. Un atacante no autenticado puede llevar a cabo una petición HTTP desde el servidor vulnerable a cualquier dirección en la red interna y obtener su respuesta (que podría, por ejemplo, tener una carga útil de JavaScript para el XSS resultante). El problema puede ser explotado para omitir los límites de la red, obtener datos confidenciales o atacar a otros hosts de la red interna
