CVE-2026-2017 identifies a stack-based buffer overflow vulnerability in the IP-COM W30AP wireless access point, specifically in firmware version 1.0.0.11(1340). The vulnerability resides in the R7WebsSecurityHandler function, which processes POST requests to the /goform/wx3auth endpoint. By crafting malicious input data to this handler, an attacker can overflow the stack buffer, potentially overwriting the return address or other control data on the stack. This can lead to arbitrary code execution with the privileges of the affected process, typically root or system-level on the device. The vulnerability is remotely exploitable without any authentication or user interaction, making it highly dangerous. The CVSS 4.0 base score of 9.3 reflects the critical nature of this flaw, with attack vector being network-based, low attack complexity, and no privileges or user interaction required. The vulnerability compromises confidentiality, integrity, and availability of the device and the network it supports. The vendor was notified but has not responded or provided a patch, and a public exploit is available, increasing the urgency for defensive measures. The affected device is often used in enterprise and small to medium business wireless networks, making it a valuable target for attackers seeking network access or lateral movement.

For European organizations, exploitation of this vulnerability could lead to full compromise of IP-COM W30AP devices, enabling attackers to intercept, manipulate, or disrupt wireless network traffic. This threatens the confidentiality of sensitive communications, the integrity of network data, and the availability of wireless services. Compromised devices could be used as footholds for further attacks within corporate networks or as launch points for attacks against other connected systems. Given the critical score and remote exploitability, the risk of widespread disruption or data breaches is significant, especially in sectors relying heavily on wireless connectivity such as finance, healthcare, manufacturing, and government. The lack of vendor response and patch availability increases exposure time, raising the likelihood of exploitation in the wild. Organizations with IP-COM W30AP devices in their infrastructure face urgent operational and security risks that could impact compliance with European data protection regulations such as GDPR if sensitive data is exposed.

1. Immediately identify and inventory all IP-COM W30AP devices running firmware version 1.0.0.11(1340) within the network. 2. Isolate vulnerable devices on segmented network zones with strict access controls to limit exposure. 3. Disable or restrict access to the /goform/wx3auth endpoint if possible, or block POST requests targeting this path at the network perimeter. 4. Monitor network traffic and device logs for unusual POST requests or signs of exploitation attempts. 5. Employ intrusion detection/prevention systems (IDS/IPS) with signatures for this vulnerability or exploit. 6. If feasible, replace vulnerable devices with alternative hardware from vendors with active security support. 7. Engage with IP-COM for updates or patches and subscribe to vulnerability advisories for timely information. 8. Implement compensating controls such as VPNs or encrypted tunnels to protect wireless traffic until the vulnerability is remediated. 9. Conduct user awareness and incident response training focused on detecting and responding to network device compromises. 10. Plan for rapid patch deployment once a vendor fix becomes available.
