CVE-2026-25037 is an OS command injection vulnerability identified in Copeland XWEB 300D PRO, specifically in versions 1.12.1 and prior. The vulnerability arises from improper input validation when processing the LCD state configuration during system setup. An authenticated attacker with high privileges can craft a malicious LCD state configuration that, when processed by the device, results in arbitrary OS command execution. This leads to remote code execution (RCE) on the affected system, allowing the attacker to compromise the device fully. The vulnerability is classified under CWE-78 (Improper Neutralization of Special Elements used in an OS Command). The CVSS v3.1 base score is 8.0, reflecting high severity with network attack vector, high attack complexity, required privileges, no user interaction, and impacts to confidentiality, integrity, and availability with scope change. Although no known exploits are currently reported in the wild, the potential for impactful attacks exists, especially in industrial control environments where XWEB 300D PRO devices are deployed. The vulnerability's exploitation could disrupt critical operations, leak sensitive data, or allow persistent unauthorized access. The lack of available patches at the time of reporting necessitates immediate mitigation efforts to reduce risk.

The vulnerability enables remote code execution on Copeland XWEB 300D PRO devices, potentially allowing attackers to gain full control over affected systems. This can lead to unauthorized disclosure of sensitive information, manipulation or destruction of data, and disruption of device availability. Given that these devices are often used in industrial control systems, exploitation could result in operational downtime, safety hazards, and significant financial losses. The requirement for authenticated access with high privileges limits exploitation to insiders or attackers who have already compromised credentials, but the impact remains severe due to the elevated control gained post-exploitation. The scope change indicated in the CVSS score suggests that the vulnerability could affect other components or connected systems, amplifying the risk. Organizations relying on these devices for critical infrastructure or industrial automation face heightened risks of operational disruption and potential cascading effects on broader systems.

1. Immediately restrict access to the management interfaces of Copeland XWEB 300D PRO devices to trusted personnel only, using network segmentation and strong access controls. 2. Enforce multi-factor authentication and regularly audit user privileges to minimize the risk of credential compromise or misuse. 3. Monitor device logs and configuration changes for signs of suspicious activity, particularly modifications to LCD state configurations. 4. Implement strict input validation and sanitization controls at the network perimeter to detect and block malformed or malicious configuration payloads. 5. Coordinate with Copeland for timely release and deployment of official patches or firmware updates addressing this vulnerability. 6. Until patches are available, consider disabling or limiting features that process LCD state configurations if operationally feasible. 7. Conduct regular security assessments and penetration testing focused on industrial control devices to identify and remediate similar vulnerabilities proactively. 8. Maintain an incident response plan tailored to industrial control system compromises to enable rapid containment and recovery.
