CVE-2024-45410

Estado: AnalizadaAlta (7.5)—💥 PoC

Traefik is a golang, Cloud Native Application Proxy. When a HTTP request is processed by Traefik, certain HTTP headers such as X-Forwarded-Host or X-Forwarded-Port are added by Traefik before the request is routed to the application. For a HTTP client, it should not be possible to remove or modify these headers. Since the application trusts the value of these headers, security implications might arise, if they can be modified. For HTTP/1.1, however, it was found that some of theses custom headers can indeed be removed and in certain cases manipulated.

Leer descripción completaMostrar menos

The attack relies on the HTTP/1.1 behavior, that headers can be defined as hop-by-hop via the HTTP Connection header. This issue has been addressed in release versions 2.11.9 and 3.1.3. Users are advised to upgrade. There are no known workarounds for this vulnerability.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.

      "value": "Traefik es un proxy de aplicación nativo de la nube (golang). Cuando Traefik procesa una solicitud HTTP, Traefik agrega ciertos encabezados HTTP como X-Forwarded-Host o X-Forwarded-Port antes de que la solicitud se envíe a la aplicación. Para un cliente HTTP, no debería ser posible eliminar o modificar estos encabezados. Dado que la aplicación confía en el valor de estos encabezados, podrían surgir implicaciones de seguridad si se pueden modificar. Sin embargo, para HTTP/1.1, se descubrió que algunos de estos encabezados personalizados sí se pueden eliminar y, en ciertos casos, manipular. El ataque se basa en el comportamiento de HTTP/1.1, que permite definir los encabezados como salto a salto a través del encabezado de conexión HTTP. Este problema se ha solucionado en las versiones de lanzamiento 2.11.9 y 3.1.3. Se recomienda a los usuarios que actualicen. No se conocen workarounds para esta vulnerabilidad."
