Published: 05 December 2025
Summary
CVE-2025-14094 is a low-severity Command Injection (CWE-77) vulnerability in Edimax Br-6478Ac V3 Firmware. Its CVSS base score is 2.0 (Low).
Operationally, exploitation aligns with the MITRE ATT&CK technique Network Device CLI (T1059.008); ranked at the 38.3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2025-14094 is an OS command injection vulnerability affecting the Edimax BR-6478AC V3 firmware version 1.0.15. The flaw exists in the function sub_44CCE4 within the file /boafrm/formSysCmd, where manipulation of the sysCmd argument enables command injection. Published on 2025-12-05, it is associated with CWE-77 and CWE-78.
The vulnerability is exploitable remotely over the network (AV:N) with low attack complexity (AC:L), but requires high privileges (PR:H) and no user interaction (UI:N), with unchanged scope (S:U). Exploitation yields low impacts on confidentiality, integrity, and availability (C:L/I:L/A:L), resulting in a CVSS v3.1 base score of 4.7. Attackers with sufficient privileges can inject and execute arbitrary OS commands on the device.
No patches or mitigations are available from the vendor, who was contacted early but did not respond. An exploit has been published and may be used, with details available at https://github.com/Kriswu1337/CVE/blob/main/EDIMAX/1/3.md and related VulDB entries including https://vuldb.com/?ctiid.334484, https://vuldb.com/?id.334484, and https://vuldb.com/?submit.696668.
