Descriptions

Hongdian H8922 3.0.5 devices allow Directory Traversal. The /log_download.cgi log export handler does not validate user input and allows a remote attacker with minimal privileges to download any file from the device by substituting ../ (e.g., ../../etc/passwd) This can be carried out with a web browser by changing the file name accordingly. Upon visiting log_download.cgi?type=../../etc/passwd and logging in, the web server will allow a download of the contents of the /etc/passwd file.

Los dispositivos Hongdian H8922 versión 3.0.5, permiten un Salto de Directorio. El manejador de exportación de registros /log_download.cgi no comprueba la entrada del usuario y permite a un atacante remoto con privilegios mínimos descargar cualquier archivo del dispositivo sustituyendo ../ (por ejemplo, ../../etc/passwd). con un navegador web cambiando el nombre del archivo en consecuencia. Al visitar log_download.cgi?type=../../etc/passwd e iniciar sesión, el servidor web permitirá una descarga del contenido del archivo /etc/passwd
