CVE-2025-6893 is an execution with unnecessary privileges vulnerability in Moxa network security appliances and routers. The flaw is caused by broken access control in the /api/v1/setting/data endpoint, which fails to enforce the required authorization checks for configuration operations. As a result, a low-privileged authenticated user can invoke the endpoint without the permissions normally required and access or modify system configuration data. The issue can enable privilege escalation on the affected device by allowing unauthorized changes to sensitive system settings.
