CVE-2025-6894 — Execution with Unnecessary Privileges in Moxa EDF-G1002-BP Series

An Execution with Unnecessary Privileges vulnerability has been identified in Moxa’s network security appliances and routers. A flaw in the API authorization logic of the affected device allows an authenticated, low-privileged user to execute the administrative `ping` function, which is restricted to higher-privileged roles. This vulnerability enables the user to perform internal network reconnaissance, potentially discovering internal hosts or services that would otherwise be inaccessible. Repeated exploitation could lead to minor resource consumption. While the overall impact is limited, it may result in some loss of confidentiality and availability on the affected device. There is no impact on the integrity of the device, and the vulnerability does not affect any subsequent systems.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.6% (30-day exploitation probability)+7
Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Moxa EDF-G1002-BP Series, Moxa EDR-8010 Series, Moxa EDR-G9010 Series…).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
