CVE-2025-56008 is a cross-site scripting (XSS) vulnerability identified in KeeneticOS versions prior to 4.3, affecting the "Wireless ISP" page of the router's web interface. The vulnerability allows an attacker physically near the router to inject malicious scripts into the web interface. This XSS flaw can be exploited to manipulate the router's configuration interface, specifically enabling the attacker to add new users with full administrative privileges. By doing so, the attacker gains complete control over the device, including the ability to alter network settings, intercept traffic, or deploy further malicious activities within the network. The attack vector requires proximity, implying that remote exploitation over the internet is unlikely without additional network access. No CVSS score has been assigned yet, and no known exploits have been reported in the wild, but the potential impact is significant due to the administrative control gained. The vulnerability highlights a critical security weakness in the router's web interface input validation and session management. KeeneticOS users should be aware that this vulnerability compromises both the integrity and confidentiality of their network devices. The lack of patch links suggests that a fix may be forthcoming or that users should upgrade to version 4.3 or later once available. This vulnerability is particularly concerning for environments where routers are accessible to unauthorized individuals, such as public or semi-public locations.

For European organizations, the impact of CVE-2025-56008 can be severe. Organizations relying on Keenetic routers for network connectivity could face unauthorized administrative access if an attacker gains physical proximity to the device. This could lead to full device takeover, allowing attackers to modify network configurations, intercept or redirect traffic, and potentially launch further attacks within the internal network. Confidentiality of sensitive communications could be compromised, and the integrity of network operations disrupted. Critical infrastructure sectors, small and medium enterprises, and public institutions using these routers are at particular risk. The requirement for physical proximity limits the attack scope but does not eliminate risk in environments where routers are accessible to visitors, contractors, or in shared office spaces. Additionally, compromised routers could be used as pivot points for lateral movement or persistent network presence, increasing the overall threat to organizational cybersecurity posture.

1. Upgrade KeeneticOS to version 4.3 or later as soon as the patch addressing this vulnerability is released. 2. Restrict physical access to routers by placing them in locked or secure enclosures to prevent unauthorized proximity. 3. Regularly audit user accounts on routers to detect and remove any unauthorized users with elevated privileges. 4. Implement network segmentation to limit the impact of a compromised router on critical systems. 5. Monitor router logs and network traffic for unusual activity indicative of unauthorized access or configuration changes. 6. Educate staff about the risks of physical access to network devices and enforce policies to minimize exposure. 7. If possible, disable or restrict access to the "Wireless ISP" configuration page or limit it to trusted IP addresses or VLANs. 8. Employ additional network security controls such as intrusion detection systems (IDS) to detect anomalous behavior stemming from compromised devices.
