Summary
ComSndFTP FTP Server version 1.3.7 Beta contains a format string vulnerability in its handling of the USER command. By sending a specially crafted username containing format specifiers, a remote attacker can overwrite a hardcoded function pointer in memory (specifically WSACleanup from Ws2_32.dll). This allows the attacker to redirect execution flow and bypass DEP protections using a ROP chain, ultimately leading to arbitrary code execution. The vulnerability is exploitable without authentication and affects default configurations.

"value": "ComSndFTP FTP Server versi\u00f3n 1.3.7 Beta contiene una vulnerabilidad de cadena de formato en su gesti\u00f3n del comando USER. Al enviar un nombre de usuario especialmente manipulado con especificadores de formato, un atacante remoto puede sobrescribir un puntero de funci\u00f3n codificado en memoria (espec\u00edficamente, WSACleanup de Ws2_32.dll). Esto permite al atacante redirigir el flujo de ejecuci\u00f3n y eludir las protecciones DEP mediante una cadena ROP, lo que finalmente provoca la ejecuci\u00f3n de c\u00f3digo arbitrario. Esta vulnerabilidad se puede explotar sin autenticaci\u00f3n y afecta a las configuraciones predeterminadas."
