CVE-2025-15162 identifies a stack-based buffer overflow vulnerability in the Tenda WH450 router firmware version 1.0.0.18. The flaw exists in an unspecified functionality related to the /goform/RouteStatic endpoint, specifically through manipulation of the 'page' argument. This improper input validation leads to a stack buffer overflow, which can be exploited remotely without requiring authentication or user interaction. The vulnerability allows attackers to potentially execute arbitrary code on the device, compromising confidentiality, integrity, and availability. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P) indicates network attack vector, low attack complexity, no privileges or user interaction required, but high impact on all security properties. Although no exploits are currently observed in the wild, public disclosure of exploit code increases the likelihood of active exploitation. The vulnerability affects only firmware version 1.0.0.18, and no official patches have been linked yet. The Tenda WH450 is a consumer and small business router, often deployed in home and small office networks. Successful exploitation could allow attackers to gain control over the device, intercept or manipulate network traffic, or disrupt network availability. This poses risks especially to organizations relying on these routers for perimeter or internal routing functions.

For European organizations, the impact of CVE-2025-15162 can be significant. Compromise of Tenda WH450 routers could lead to unauthorized access to internal networks, interception of sensitive data, and disruption of business operations. Small and medium enterprises (SMEs) and home office setups using these routers are particularly vulnerable due to potentially weaker network defenses. Critical infrastructure sectors that utilize these devices for network connectivity may face operational disruptions or targeted attacks. The ability to execute code remotely without authentication increases the attack surface and risk of widespread exploitation. Data confidentiality and integrity could be severely affected, leading to potential regulatory and compliance issues under GDPR. Network availability could also be impacted, causing downtime and service degradation. The lack of patches at the time of disclosure necessitates immediate risk mitigation to prevent exploitation.

1. Immediately identify and inventory all Tenda WH450 devices running firmware version 1.0.0.18 within the network. 2. Monitor vendor channels closely for official firmware updates or patches addressing CVE-2025-15162 and apply them promptly upon release. 3. Until patches are available, implement network segmentation to isolate vulnerable routers from critical systems and sensitive data. 4. Employ firewall rules to restrict inbound traffic to the /goform/RouteStatic endpoint or block suspicious HTTP requests targeting this path. 5. Use intrusion detection/prevention systems (IDS/IPS) to detect anomalous traffic patterns indicative of exploitation attempts. 6. Disable remote management interfaces on affected devices if not strictly necessary. 7. Educate network administrators about the vulnerability and signs of compromise. 8. Consider replacing vulnerable devices with models from vendors with stronger security track records if patching is delayed. 9. Conduct regular security audits and penetration testing focusing on router and network device security. 10. Maintain up-to-date backups and incident response plans to quickly recover from potential breaches.
