CVE-2022-39348

Estado: ModificadaMedia (5.4)—

Twisted es un framework basado en eventos para aplicaciones de Internet. Comenzó con la versión 0.9.4, cuando el encabezado del host no coincide con un host configurado "twisted.web.vhost.NameVirtualHost" devolverá un recurso "NoResource" que hace que el encabezado del Host no sea escondido en la respuesta 404 permitiendo la inyección de HTML y scripts. En la práctica esto debería ser muy difícil de explotar ya que ser capaz de modificar el encabezado Host de una petición HTTP normal implica que uno ya está en una posición privilegiada. Este problema ha sido corregido en versión 22.10.0rc1. No se presenta mitigaciones conocidas

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
