Published: 04 April 2025
Summary
CVE-2025-28146 is a critical-severity Code Injection (CWE-94) vulnerability in Edimax Br-6478Ac V3 Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Network Device CLI (T1059.008); ranked in the top 2.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
The vulnerability CVE-2025-28146 is a command injection flaw, tracked as CWE-94, in the Edimax AC1200 Wave 2 Dual-Band Gigabit Router BR-6478AC V3 running firmware 1.0.15. It resides in the handling of the fota_url parameter passed to the /boafrm/formLtefotaUpgradeQuectel endpoint and received a CVSS 3.1 score of 9.8.
Remote attackers with no credentials or user interaction required can supply crafted input to the endpoint and execute arbitrary operating-system commands on the device. Successful exploitation yields complete control over the router, enabling full read, write, and disruption of device functions and any attached networks.
Public references consist of a technical gist and GitHub repository that reproduce the flaw; neither source nor the CVE record itself documents vendor patches, firmware updates, or recommended mitigations. The associated EPSS score has reached 0.3888 at its observed peak.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
