CVE-2025-24989

Estado: AnalizadaCrítica (9.8)⚠ Explotación activa

An improper access control vulnerability in Power Pages allows an unauthorized attacker to elevate privileges over a network potentially bypassing the user registration control. This vulnerability has already been mitigated in the service and all affected customers have been notified. This update addressed the registration control bypass. Affected customers have been given instructions on reviewing their sites for potential exploitation and clean up methods. If you've not been notified this vulnerability does not affect you.

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).

CISA KEV — explotada activamente

🎯 Técnicas ATT&CK

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

Vector CVSS AV:N/AC:L/PR:N sin interacción del usuario indica explotación remota directa (T1190). El bypass del control de registro permite elevación de privilegios no autorizada, lo que traduce en acceso a cuentas comprometidas (T1078.001, T1098.001). CWE-284 confirma control de acceso deficiente.

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.
