CVE-2023-7305
SmartBI V8, V9, and V10 contain an unrestricted file upload vulnerability via the RMIServlet request handling logic. Under certain configurations or usage patterns, attackers can send specially crafted requests that cause the application to perform sensitive operations or execute arbitrary code on the host. The vendor released a fix in July 2023 to address the underlying flaw. VulnCheck has observed this vulnerability being exploited in the wild.

Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.53%
- Percentil entre todas las CVEs puntuadas: 43
- Fecha de la puntuación: 6/10/2026
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.
- Explotación
T1190Exploit Public-Facing Applicationinitial access85 % - Impacto principal
T1505.003Web Shellpersistence80 % - Impacto secundario
T1059Command and Scripting Interpreterexecution75 %
CWE-434 (unrestricted file upload) con AV:N permite explotar aplicación web expuesta (T1190). Carga de ficheros en servidor web = web shell (T1505.003); ejecución de código arbitraria sugiere T1059 secundario.
