CVE-2026-44668

Estado: AplazadaCrítica (9.8)—

FACTION is a PenTesting Report Generation and Collaboration Framework. Prior to 1.8.3, AccessControlInterceptor, the authentication gate for all Struts2 actions, unconditionally calls invocation.invoke() without checking for a valid session. Four action methods in BoilerPlateConfig perform no local session check either, allowing an unauthenticated attacker to read, overwrite, deactivate, and permanently delete any boilerplate template in the system. This vulnerability is fixed in 1.8.3.

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.

Vulnerabilidad en aplicación web expuesta (Struts2) explotable sin autenticación ni privilegios (AV:N/PR:N). El fallo de control de sesión permite acceso no autenticado y manipulación de datos (lectura, sobrescritura, eliminación de plantillas).

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.
