  3. CVE-2019-25681
Xlight FTP Server 3.9.1 contains a structured exception handler (SEH) overwrite vulnerability that allows local attackers to crash the application and overwrite SEH pointers by supplying a crafted buffer string. Attackers can inject a 428-byte payload through the program execution field in virtual server configuration to trigger a buffer overflow that corrupts the SEH chain and enables potential code execution.

Summary
  • (es) Xlight FTP Server 3.9.1 contiene una vulnerabilidad de sobrescritura del gestor de excepciones estructuradas (SEH) que permite a atacantes locales bloquear la aplicación y sobrescribir punteros SEH al proporcionar una cadena de búfer manipulada. Los atacantes pueden inyectar una carga útil de 428 bytes a través del campo de ejecución del programa en la configuración del servidor virtual para desencadenar un desbordamiento de búfer que corrompe la cadena SEH y permite la ejecución potencial de código.
