Cross Site Scripting vulnerability in Key Systems Inc Global Facilities Management Software v. 20230721a allows a remote attacker to execute arbitrary code via the function parameter.

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.

CWE-79 (XSS) con AV:N/AC:L/PR:N/UI:R confirma T1189. La ejecución de JavaScript en navegador (T1059.007) es impacto directo; potencial acceso a datos del DOM (T1005) como secundario.

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.
