Estado: AnalizadaCrítica (9.3)—

Adobe Experience Manager Forms JEE versions LTS SP1, 6.5.24.0 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by an attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim's browser when they browse to the page containing the vulnerable field, potentially gaining elevated access or control over the victim's account or session. Scope is changed.

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 formularios de AEM Forms (CWE-79, UI:R, vector red sin autenticación). JavaScript malicioso ejecutado en navegador víctima (T1059.007) permite acceso elevado a cuenta/sesión (T1078).

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.
