CVE-2026-24663 is an OS command injection vulnerability identified in Copeland XWEB 300D PRO, specifically affecting version 1.12.1 and earlier. The flaw exists in the device’s libraries installation route, where input from incoming requests is not properly sanitized or validated before being incorporated into system-level commands. This lack of input validation allows an unauthenticated remote attacker to craft malicious requests that inject arbitrary OS commands, leading to remote code execution (RCE) on the affected device. The vulnerability is classified under CWE-78, which covers improper neutralization of special elements used in OS commands. The CVSS v3.1 base score of 9.0 reflects the critical nature of this vulnerability, with attack vector being network-based (AV:N), no privileges required (PR:N), no user interaction needed (UI:N), and a scope change (S:C) indicating that the vulnerability affects resources beyond the initially vulnerable component. The impact on confidentiality, integrity, and availability is high, as an attacker can fully control the device, potentially disrupting operations or exfiltrating sensitive data. Although no public exploits are currently known, the vulnerability’s characteristics make it a prime candidate for exploitation once weaponized. The absence of available patches at the time of disclosure increases the urgency for affected organizations to implement compensating controls. Given that Copeland XWEB 300D PRO is used in industrial control systems and possibly critical infrastructure environments, the vulnerability poses a significant risk to operational technology (OT) environments.

The impact of CVE-2026-24663 is severe for organizations deploying Copeland XWEB 300D PRO devices, particularly in industrial and critical infrastructure sectors. Successful exploitation allows attackers to execute arbitrary commands remotely without authentication, leading to full system compromise. This can result in unauthorized access to sensitive operational data, disruption or manipulation of industrial processes, and potential physical damage if control systems are affected. The compromise of such devices can also serve as a foothold for lateral movement within OT and IT networks, increasing the risk of broader organizational impact. Confidentiality is at risk due to potential data leakage, integrity is compromised by unauthorized command execution, and availability may be disrupted by malicious actions or system instability. The critical severity and network accessibility of the vulnerability make it a high-priority threat that could be exploited by nation-state actors or cybercriminals targeting industrial environments.

1. Immediate network segmentation: Isolate Copeland XWEB 300D PRO devices from general IT networks and restrict access to trusted management networks only. 2. Implement strict firewall rules to block unauthorized inbound traffic to the libraries installation route and related management interfaces. 3. Monitor network traffic for unusual or malformed requests targeting the installation route to detect potential exploitation attempts. 4. Employ intrusion detection/prevention systems (IDS/IPS) with signatures or anomaly detection tuned for command injection patterns. 5. Disable or restrict the libraries installation functionality if not required operationally to reduce the attack surface. 6. Engage with Copeland for official patches or firmware updates and apply them promptly once available. 7. Conduct regular security audits and penetration testing focused on OT devices to identify similar vulnerabilities. 8. Maintain up-to-date asset inventories and ensure all devices run supported firmware versions. 9. Establish incident response plans specific to OT environments to quickly contain and remediate exploitation attempts.
