Estado: AnalizadaAlta (7.7)—

Kentico Xperience 13 is vulnerable to a stored cross-site scripting attack via a form component, allowing an attacker to hijack a victim user’s session and perform actions in their security context.

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.

XSS almacenado en componente de formulario (CWE-79) con UI:P permite inyectar scripts que secuestran sesiones (T1078: hijack session). Pista sugiere T1189 e impactos de ejecución web.

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.
