Detalles técnicos trazas, registros y código del informe original

URLModificationMiddleware resolves named-URL lookups
              against unfiltered Model.objects before RBAC. The 403→404
              shim only rewrites 403 responses, leaving the pk=0 miss
              path with a different 404 detail string. Differential
              "Not found." vs "No <Model> matches..." reveals whether
              a named resource (org, credential, inventory, host) exists
              anywhere on the platform. Enables cross-tenant internal
              hostname enumeration.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N
Puntuación base: 5

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.30%
Percentil entre todas las CVEs puntuadas: 21
Fecha de la puntuación: 5/10/2026

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

ExplotaciónT1210 Exploitation of Remote Serviceslateral movement72 %
Impacto principalT1526 Cloud Service Discoverydiscovery68 %
Impacto secundarioT1590.002 DNSreconnaissance65 %

AV:N/PR:L sin UI permite acceso remoto autenticado a recurso vulnerable (T1210). Diferencias en mensajes 404 permiten enumerar recursos internos y nombres de hosts entre tenants (T1526, T1590.002).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
