Authenticated root command execution via unfiltered DDNS name
Published Dec 25, 2025 · Updated Dec 25, 2025
Command injection in JD Cloud Wireless Bao BE6500 4.4.1.r4308 allows remote authenticated users to execute commands as root via DDNS settings. The /jdcapi sub_4780 function copies ddns_name without filtering, formats it into an /etc/init.d/ddns command, and passes the result to system(). An authorized web session is required; successful injection grants root-level control of the router, including the ability to alter data or interrupt service.
