## What is CVE-2025-6893?

CVE-2025-6893 is a critical missing authorization vulnerability in Moxa EDF-G1002-BP Series, published on 17 Oct 2025. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

An Execution with Unnecessary Privileges vulnerability has been identified in Moxa’s network security appliances and routers. A flaw in broken access control has been identified in the /api/v1/setting/data endpoint of the affected device. This flaw allows a low-privileged authenticated user to call the API without the required permissions, thereby gaining the ability to access or modify system configuration data. Successful exploitation may lead to privilege escalation, allowing the attacker to access or modify sensitive system settings. While the overall impact is high, there is no loss of confidentiality or integrity within any subsequent systems.

Weakness: CWE-250 (Execution with Unnecessary Privileges)
