CVE-2026-3037 is an OS command injection vulnerability identified in Copeland's XWEB 300D PRO device, specifically in versions 1.12.1 and earlier. The vulnerability arises from improper input sanitization in the MBird SMS service URL and/or code parameters processed via the utility route during system setup. An authenticated attacker can inject malicious commands into these inputs, which the system executes, resulting in remote code execution (RCE). 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, indicating high severity, with vector AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H. This means the attack is network accessible but requires high attack complexity and privileges, no user interaction, and impacts confidentiality, integrity, and availability with a scope change. Although no public exploits are known, the vulnerability poses a significant risk due to the potential for full system compromise. The affected product is typically used in industrial or building automation environments, where system integrity and availability are critical. The lack of available patches at the time of publication necessitates immediate mitigation efforts.

If exploited, this vulnerability allows attackers to execute arbitrary OS commands remotely with the privileges of the affected service, potentially leading to full system compromise. This can result in unauthorized data disclosure, modification, or deletion, disruption of device functionality, and potential pivoting to other networked systems. For organizations relying on Copeland XWEB 300D PRO devices in critical infrastructure or industrial control systems, this could lead to operational downtime, safety hazards, and significant financial and reputational damage. The scope of impact is elevated due to the vulnerability's ability to affect confidentiality, integrity, and availability simultaneously. Given the device’s role in automation, exploitation could disrupt essential services or processes, amplifying the threat to organizations worldwide.

1. Immediately restrict access to the management interfaces of Copeland XWEB 300D PRO devices to trusted administrators only, preferably via VPN or isolated management networks. 2. Enforce strong authentication and limit user privileges to reduce the risk of authenticated exploitation. 3. Monitor and audit logs for unusual activity related to the MBird SMS service or utility route parameters. 4. Implement input validation and sanitization at network boundaries or via web application firewalls to detect and block suspicious command injection attempts targeting the vulnerable parameters. 5. Coordinate with Copeland for official patches or firmware updates and apply them as soon as they become available. 6. If patching is delayed, consider disabling or restricting the MBird SMS service functionality if it is not essential. 7. Conduct regular vulnerability assessments and penetration testing focused on industrial control systems to detect similar issues proactively. 8. Maintain network segmentation to isolate vulnerable devices from critical networks and limit lateral movement in case of compromise.
