Authenticated privilege escalation via DDNS uptime request
Published Feb 16, 2026 · Updated Feb 16, 2026
Privilege escalation in JD Cloud Box AX6600 4.5.1.r4533 allows remote authenticated users to gain elevated access via a crafted DDNS uptime request. The jdcweb_rpc component dispatches the /jdcapi request to web_get_ddns_uptime, but the public record does not disclose the manipulated field or missing privilege check. Low-privileged network access is required; exploitation crosses the router's privilege boundary, while the elevated role and permitted actions remain undisclosed.
