CVE-2023-3128
Estado: ModificadaCrítica (9.8)—💥 PoC
Grafana is validating Azure AD accounts based on the email claim.
On Azure AD, the profile email field is not unique and can be easily modified.
This leads to account takeover and authentication bypass when Azure AD OAuth is configured with a multi-tenant app.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 9.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 4.00%
- Percentil entre todas las CVEs puntuadas: 90
- Fecha de la puntuación: 7/10/2026
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).
💥 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.
- Prueba de concepto en GitHub (no verificada) · Lista de pruebas de concepto en GitHub
