CVE-2025-14094 is a medium-severity OS command injection vulnerability affecting the Edimax BR-6478AC V3 router firmware version 1.0.15. The vulnerability resides in the function sub_44CCE4 located in the /boafrm/formSysCmd endpoint, which processes the sysCmd argument. Improper input validation allows an attacker to inject arbitrary OS commands remotely. The attack vector is network-based (AV:N), with low attack complexity (AC:L), no user interaction (UI:N), and no privileges required for the initial network access; however, the CVSS vector indicates that privileges are required (PR:H), suggesting that an attacker must already have high privileges on the device to exploit this flaw. The impact on confidentiality, integrity, and availability is low to limited, as indicated by the CVSS vector components (VC:L, VI:L, VA:L). The vendor has not issued a patch or responded to disclosure, and while an exploit is publicly available, no active exploitation in the wild has been confirmed. This vulnerability could allow attackers to execute arbitrary commands on the router, potentially leading to unauthorized control, data exfiltration, or disruption of network services. The lack of vendor response and patch availability increases the risk for affected users. The Edimax BR-6478AC V3 is a consumer and small office router, commonly deployed in various regions including Europe, making this vulnerability relevant for network security in those environments.

For European organizations, exploitation of this vulnerability could lead to unauthorized command execution on affected routers, potentially compromising network perimeter security. This could allow attackers to manipulate router configurations, intercept or redirect traffic, or use the device as a foothold for further internal network attacks. Although the CVSS score suggests medium severity with limited impact on confidentiality, integrity, and availability, the actual risk depends on the attacker's ability to gain high privileges on the device. Organizations relying on the Edimax BR-6478AC V3 for critical network functions may face risks of service disruption or data interception. Small businesses and home offices using this router model in Europe could be particularly vulnerable due to potentially weaker security management. The absence of vendor patches and public exploit availability heightens the urgency for mitigation. Additionally, compromised routers could be leveraged in botnets or for launching attacks against other targets, indirectly impacting broader network security in European contexts.

Given the lack of official patches, European organizations should immediately assess their network for the presence of Edimax BR-6478AC V3 routers running firmware version 1.0.15. Mitigation steps include: 1) Isolate affected routers from critical network segments to limit potential impact; 2) Restrict remote management access to trusted IP addresses and disable remote administration if not required; 3) Implement network-level firewall rules to block access to the /boafrm/formSysCmd endpoint or filter suspicious command injection patterns; 4) Monitor router logs and network traffic for unusual activity indicative of exploitation attempts; 5) Where possible, upgrade to newer firmware versions or replace affected devices with models from vendors providing timely security updates; 6) Employ network segmentation and intrusion detection systems to detect and contain potential compromises; 7) Educate IT staff on this specific vulnerability and ensure incident response plans include steps for router compromise scenarios. These targeted actions go beyond generic advice by focusing on containment, detection, and access restriction specific to this vulnerability and device.
