CVE-2026-73807

Estado: AplazadaCrítica (9.3)—

The mySCADA myPRO Manager command API does not properly enforce authentication for privileged functions. An unauthenticated attacker with network access to the affected API could exploit this vulnerability to access privileged management functions.

CVSS

Puntuación base: 9.3

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.78%
Percentil entre todas las CVEs puntuadas: 54
Fecha de la puntuación: 6/10/2026

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).

AV:N sin autenticación (PR:N, UI:N) en API SCADA indica explotación remota directa (T1190). Acceso a funciones privilegiadas sin autenticación permite obtener acceso con permisos elevados (T1078) y potencialmente ejecución de comandos administrativos (T1059).

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.
