CVE-2025-64066

Estado: AnalizadaAlta (8.6)—

Primakon Pi Portal 1.0.18 REST /api/v2/user/register endpoint suffers from a Broken Access Control vulnerability. The endpoint fails to implement any authorization checks, allowing unauthenticated attackers to perform POST requests to register new user accounts in the application's local database. This bypasses the intended security architecture, which relies on an external Identity Provider for initial user registration and assumes that internal user creation is an administrative-only function. This vector can also be chained with other vulnerabilities for privilege escalation and complete compromise of application. This specific request can be used to also enumerate already registered user accounts, aiding in social engineering or further targeted attacks.

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).

🎯 Técnicas ATT&CK

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

REST API expuesta sin autenticación (AV:N, PR:N, UI:N) permite crear cuentas locales (T1136) y obtener acceso con credenciales válidas (T1078). La enumeración de usuarios (T1087) se menciona explícitamente en el texto.

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.
