CVE-2026-24452 is an OS command injection vulnerability classified under CWE-78, affecting Copeland XWEB 300D PRO devices running firmware version 1.12.1 and earlier. The vulnerability arises from improper input validation when processing template files supplied to the device's route, allowing an authenticated attacker with high privileges to inject and execute arbitrary operating system commands remotely. This leads to remote code execution (RCE) on the affected device, compromising the system's confidentiality, integrity, and availability. The vulnerability requires the attacker to have authenticated access with elevated privileges, but does not require any additional user interaction. The CVSS v3.1 base score is 8.0, reflecting a high severity due to the potential for complete system compromise and the scope of impact affecting the device and potentially connected networks. No public exploits have been reported yet, but the vulnerability's nature and impact make it a critical concern for organizations relying on these devices, especially in industrial control and critical infrastructure environments. The lack of available patches at the time of reporting necessitates immediate mitigation efforts to reduce exposure.

The impact of CVE-2026-24452 is significant for organizations using Copeland XWEB 300D PRO devices, particularly in industrial control systems and critical infrastructure sectors. Successful exploitation allows attackers to execute arbitrary commands remotely, potentially leading to full system compromise, data theft, disruption of operations, or use of the device as a pivot point for further network intrusion. The compromise of these devices could disrupt industrial processes, cause safety hazards, or lead to operational downtime. Given the device's role in managing or monitoring industrial environments, the integrity and availability of critical systems are at risk. Organizations worldwide that deploy these devices in manufacturing, energy, water treatment, or other critical sectors could face operational, financial, and reputational damage if this vulnerability is exploited.

1. Immediately restrict access to the management interfaces of Copeland XWEB 300D PRO devices to trusted personnel and networks only, using network segmentation and firewall rules. 2. Enforce strong authentication and privilege management to limit access to high-privilege accounts required for exploitation. 3. Monitor device logs and network traffic for unusual template file uploads or command execution attempts. 4. Disable or restrict the functionality that processes template files if feasible until a patch is available. 5. Engage with Copeland for official patches or firmware updates addressing this vulnerability and apply them promptly once released. 6. Implement intrusion detection/prevention systems tailored to detect exploitation attempts targeting this vulnerability. 7. Conduct regular security audits and vulnerability assessments on industrial control devices to identify and remediate similar risks proactively.
