CVE-2025-14093 is an OS command injection vulnerability identified in the Edimax BR-6478AC V3 router firmware version 1.0.15. The vulnerability resides in the function sub_416990, specifically in the /boafrm/formTracerouteDiagnosticRun endpoint, which processes traceroute diagnostic requests. The 'host' parameter is insufficiently sanitized, allowing an attacker to inject arbitrary operating system commands. This injection can be exploited remotely without requiring authentication or user interaction, increasing the attack surface significantly. The vulnerability has a CVSS 4.0 base score of 5.1, indicating medium severity, with network attack vector, low complexity, no privileges required, and no user interaction needed. The vendor was notified but has not issued any patches or advisories. The exploit code has been made public, raising the risk of exploitation despite no current reports of active attacks. Successful exploitation could allow attackers to execute commands on the router, potentially leading to device compromise, network traffic interception, or denial of service. The lack of vendor response and patch availability heightens the urgency for affected users to implement compensating controls.

For European organizations, this vulnerability poses a significant risk to network security and operational continuity. Compromise of the Edimax BR-6478AC V3 routers could allow attackers to execute arbitrary commands, potentially leading to unauthorized access to internal networks, interception or manipulation of network traffic, and disruption of network services. This is particularly critical for organizations relying on these routers for perimeter defense or remote connectivity. The ability to exploit the vulnerability remotely without authentication increases the likelihood of attacks originating from external threat actors. Additionally, the absence of vendor patches means organizations must rely on mitigations or device replacement, which could incur operational costs and complexity. Critical infrastructure sectors, SMEs, and enterprises using these routers in Europe could face increased exposure to espionage, data breaches, or service outages.

Given the lack of official patches, European organizations should implement the following specific mitigations: 1) Immediately disable remote management interfaces on the Edimax BR-6478AC V3 routers to reduce exposure. 2) Restrict network access to the router’s management interface using firewall rules or network segmentation, allowing only trusted internal IP addresses. 3) Monitor network traffic for unusual traceroute diagnostic requests or unexpected command execution patterns indicative of exploitation attempts. 4) Where feasible, replace affected devices with models from vendors with active security support and timely patching. 5) If replacement is not immediately possible, consider rolling back to a previous firmware version if it is known to be unaffected. 6) Employ intrusion detection/prevention systems tuned to detect command injection patterns targeting router management endpoints. 7) Maintain up-to-date asset inventories to identify all affected devices and prioritize remediation efforts. 8) Educate IT staff on this vulnerability and ensure incident response plans include steps for potential exploitation scenarios.
