                           - Report Details (from Author's Report)

                     - Summary

                         In this firmware version, the web server is not properly handling the ntp_zone_val field in the CGI request for /goform/set_ntp. This allows an attacker to craft a malicious ntp_zone_val field and send a malicious HTTP request to the /goform/set_ntp CGI, leading to command execution with administrator privileges on the firmware file system.
