Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly prevents OS command injection by requiring validation of the untrusted 'host' input in the traceroute diagnostic function.
Mandates identification, prioritization, and remediation of the specific command injection flaw, addressing the absence of vendor patches.
Limits potential damage from injected commands by enforcing least privilege on the high-privilege web server process handling the vulnerable function.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
OS command injection in router web diagnostic form (/boafrm/formTracerouteDiagnosticRun) enables indirect command execution (T1202) via unsanitized 'host' input and network device CLI abuse (T1059.008) for arbitrary OS command execution.
NVD Description
A vulnerability was detected in Edimax BR-6478AC V3 1.0.15. Impacted is the function sub_416990 of the file /boafrm/formTracerouteDiagnosticRun. The manipulation of the argument host results in os command injection. The attack can be launched remotely. The exploit is now public…

Deeper analysisAI
CVE-2025-14093 is an OS command injection vulnerability (CWE-77, CWE-78) in the Edimax BR-6478AC V3 router running firmware version 1.0.15. The flaw affects the sub_416990 function in the /boafrm/formTracerouteDiagnosticRun component, where manipulation of the 'host' argument enables command injection.
The vulnerability is exploitable remotely over the network with low complexity but requires high privileges (PR:H), as indicated by its CVSS v3.1 base score of 4.7 (AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L). An attacker with sufficient access can achieve limited impacts on confidentiality, integrity, and availability, such as executing arbitrary OS commands.
Advisories referenced in VulDB entries and a GitHub repository detail the issue, including a public exploit. The vendor was contacted early regarding disclosure but provided no response, leaving no official patches or mitigation guidance available.
