CVE-2025-41425 is a high-severity vulnerability identified in the DuraComm Corporation's SPM-500 DP-10iN-100-MU device, classified under CWE-79, which pertains to improper neutralization of input during web page generation, commonly known as Cross-site Scripting (XSS). This vulnerability allows an attacker to inject malicious scripts into the web interface of the affected device. When legitimate users access the compromised web interface, the injected scripts can execute in their browsers, potentially leading to session hijacking, unauthorized actions, or denial of access to the interface. The CVSS 4.0 base score of 7.2 reflects a high impact due to the network attack vector (AV:N), low attack complexity (AC:L), no required authentication (PR:L indicates low privileges but still some required), and no user interaction (UI:N). The vulnerability impacts the confidentiality and integrity of the web interface by allowing script injection and can also affect availability by preventing legitimate users from accessing the interface. The affected product is an industrial or specialized communication device, which likely serves critical operational roles. No patches are currently available, and there are no known exploits in the wild, indicating the vulnerability is newly disclosed and may not yet be actively exploited. However, the lack of patches and the potential for denial of service or unauthorized control make it a significant risk. The vulnerability does not require user interaction, increasing the risk of automated exploitation. The device’s web interface is exposed to network access, which broadens the attack surface.

For European organizations, especially those in industrial, manufacturing, or critical infrastructure sectors using DuraComm's SPM-500 DP-10iN-100-MU devices, this vulnerability poses a significant risk. Exploitation could lead to disruption of operational technology management interfaces, causing downtime or loss of control over critical communication devices. This can affect production lines, supply chain communications, or other industrial processes reliant on these devices. The compromise of the web interface could also lead to lateral movement within networks, potentially exposing sensitive operational data or enabling further attacks. Given the high severity and network accessibility, attackers could remotely disrupt services without needing to authenticate or trick users, increasing the threat level. The impact on availability and integrity is particularly concerning for sectors requiring high reliability and security, such as energy, transportation, and manufacturing industries prevalent in Europe.

Organizations should immediately conduct an inventory to identify any deployment of the DuraComm SPM-500 DP-10iN-100-MU devices. Until an official patch is released, network segmentation should be enforced to isolate these devices from general IT networks and restrict access to trusted administrators only. Implement strict access controls and monitor web interface access logs for suspicious activity. Employ Web Application Firewalls (WAF) with custom rules to detect and block XSS attack patterns targeting the device’s web interface. Disable or limit web interface exposure to the internet or untrusted networks. Where possible, use VPNs or secure tunnels for remote access to the device’s management interface. Additionally, educate administrators on the risks of XSS and ensure that any input fields or parameters exposed by the device are handled cautiously. Regularly check for vendor updates or advisories to apply patches promptly once available.
