Estado: AnalizadaCrítica (10)—

Joomla Extension - joomcode.com - Unauthenticated SQL injection in read and write queries in JCTables 1.21.1 - The front-end CRUD API controller performs no Joomla token validation and no authentication check on any task. Table names, column names, and values are taken directly from request parameters and concatenated into SQL queries, allowing SQLi for reading and writing queries.

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.

SQL injection sin autenticación (CWE-89) en API pública del frontend permite lectura directa de datos (T1005) y manipulación de registros (T1565.001). Vector AV:N/PR:N/UI:N confirma explotación remota sin privilegios (T1190). Acceso a funciones de escritura sin token habilita persistencia (T1078.001

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.
