CVE-2010-20107

Estado: AplazadaAlta (8.5)—

A stack-based buffer overflow exists in FTP Synchronizer Professional <= v4.0.73.274. When the client connects to an FTP server and issues a LIST command—typically during sync preview or profile creation—the server’s response containing an overly long filename triggers a buffer overflow. This results in the corruption of the Structured Exception Handler (SEH), potentially allowing remote code execution.

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.

Vector CVSS con UI:P (interacción usuario) y AV:L (acceso local) indica ejecución en cliente. Archivo FTP preparado con nombre largo causa desbordamiento de buffer SEH, ejecutando código arbitrario.

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.
