Vulnerability from fkie_nvd - Published: 2025-07-15 13:15 - Updated: 2026-06-17 09:13
Severity
9.3 (Critical) - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N
Summary
A directory traversal vulnerability exists in ColoradoFTP Server ≤ 1.3 Build 8 for Windows, allowing unauthenticated attackers to read or write arbitrary files outside the configured FTP root directory. The flaw is due to insufficient sanitation of user-supplied file paths in the FTP GET and PUT command handlers. Exploitation is possible by submitting traversal sequences during FTP operations, enabling access to system-sensitive files. This issue affects only the Windows version of ColoradoFTP.

La falla se debe a una depuraci\u00f3n insuficiente de las rutas de archivo proporcionadas por el usuario en los controladores de comandos FTP GET y PUT. Es posible explotarla enviando secuencias de navegaci\u00f3n durante las operaciones FTP, lo que permite el acceso a archivos sensibles del sistema. Este problema afecta \u00fanicamente a la versi\u00f3n de ColoradoFTP para Windows."
