Privilege escalation via broken access control in Moxa /api/v1/setting/data endpoint
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. As a result, a low-privileged authenticated user can call this API and access or modify system configuration data that should require higher privileges. Successful exploitation can expose sensitive device settings and enable privilege escalation on the affected device.
