CVE-2012-0393

The ParameterInterceptor component in Apache Struts before 2.3.1.1 does not prevent access to public constructors, which allows remote attackers to create or overwrite arbitrary files via a crafted parameter that triggers the creation of a Java object.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
