CVE-2024-55546 identifies a stored Cross-Site Scripting (XSS) vulnerability in the web interface of the ORing IAP-420 industrial networking device, affecting firmware versions 2.01e and earlier. The vulnerability stems from improper neutralization of user-supplied input during web page generation (CWE-79), allowing malicious scripts to be persistently stored and executed when a legitimate user accesses the affected interface. The vulnerability has a CVSS 4.0 base score of 7.1, indicating high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:A). The impact on confidentiality and availability is high, with limited integrity impact. Exploitation could enable attackers to steal session cookies, perform unauthorized actions, or deliver further payloads within the trusted device management context. No patches are currently linked, and no known exploits have been reported in the wild. The vulnerability affects devices commonly used in industrial and critical infrastructure environments, where secure remote management is essential. The lack of authentication requirements for exploitation increases the risk, especially if the device management interface is exposed to untrusted networks. The vulnerability was published on December 10, 2024, by CyberDanube, highlighting the need for immediate attention from affected organizations.

For European organizations, especially those in industrial automation, manufacturing, and critical infrastructure sectors, this vulnerability poses significant risks. The ORing IAP-420 devices are often deployed in network environments controlling operational technology (OT), where compromise can lead to unauthorized control or disruption of industrial processes. Successful exploitation could result in theft of sensitive credentials, unauthorized configuration changes, or pivoting deeper into the network. This could impact confidentiality by exposing sensitive operational data, integrity by allowing unauthorized modifications, and availability by potentially disrupting device functionality. Given the high CVSS score and the device's role in network management, the threat could extend to broader operational impacts, including downtime and safety risks. European organizations with remote or internet-exposed device management interfaces are particularly vulnerable. The absence of known exploits currently provides a window for proactive mitigation before active exploitation occurs.

1. Immediately restrict access to the ORing IAP-420 web interface to trusted internal networks using network segmentation and firewall rules. 2. Implement VPN or secure tunnels for remote management to prevent direct exposure of the device interface to the internet. 3. Monitor and audit device logs for unusual activity indicative of attempted XSS exploitation or unauthorized access. 4. Deploy web application firewalls (WAFs) with rules to detect and block XSS payloads targeting the device's management interface. 5. Regularly review and sanitize all user inputs and configurations entered into the device to minimize injection opportunities. 6. Engage with ORing support channels to obtain firmware updates or patches addressing this vulnerability as soon as they become available. 7. Conduct security awareness training for personnel managing these devices to recognize phishing or social engineering attempts that could facilitate user interaction required for exploitation. 8. Consider temporary disabling of web interface features that accept user input if patching is delayed. 9. Integrate vulnerability scanning into regular security assessments to detect vulnerable device versions in the environment.
