CVE-2025-50121 is an OS command injection vulnerability classified under CWE-78 affecting Schneider Electric's EcoStruxure IT Data Center Expert version 8.3. The flaw stems from improper sanitization of user-supplied input used in operating system commands within the web interface. Specifically, when the HTTP interface is enabled, an attacker can remotely create a malicious folder that injects OS commands, leading to unauthenticated remote code execution. This means an attacker does not need credentials or user interaction to exploit the vulnerability, making it highly dangerous. The vulnerability is mitigated by default since the HTTP interface is disabled by default; however, if enabled for management convenience, it exposes the system to critical risk. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and high impact on confidentiality, integrity, and availability (VC:H/VI:H/VA:H). The scope is limited to the affected product version 8.3, and no public exploits have been reported yet. The vulnerability was reserved in June 2025 and published in July 2025, indicating recent discovery. This vulnerability could allow attackers to fully compromise data center management systems, potentially disrupting critical infrastructure operations.

For European organizations, especially those operating data centers or critical infrastructure managed by Schneider Electric's EcoStruxure IT Data Center Expert, this vulnerability poses a severe risk. Successful exploitation could lead to full system compromise, allowing attackers to execute arbitrary commands, manipulate data, disrupt operations, or pivot to other internal systems. This threatens confidentiality, integrity, and availability of critical management systems. Given the product's role in monitoring and managing data center environments, exploitation could cause operational downtime, data loss, or sabotage of infrastructure. The unauthenticated nature of the exploit increases risk, as attackers do not need valid credentials. Organizations that have enabled the HTTP interface for remote management are particularly vulnerable. The impact extends to regulatory compliance risks under GDPR and other European cybersecurity regulations if data or services are compromised. The lack of known exploits currently provides a window for proactive mitigation.

1. Immediately verify and ensure that the HTTP web interface is disabled unless absolutely necessary. Since HTTP is disabled by default, reverting to default settings reduces exposure. 2. Restrict network access to the management interface using firewalls, VPNs, or network segmentation to limit exposure to trusted administrators only. 3. Monitor network traffic and logs for suspicious folder creation attempts or anomalous HTTP requests targeting the management interface. 4. Apply any available patches or updates from Schneider Electric as soon as they are released to address this vulnerability. 5. If HTTP must be enabled, consider implementing additional protective controls such as web application firewalls (WAF) with custom rules to detect and block command injection patterns. 6. Conduct security awareness and incident response drills focused on this vulnerability to prepare for potential exploitation attempts. 7. Regularly audit and harden configurations of EcoStruxure IT Data Center Expert installations, ensuring minimal exposure of management interfaces. 8. Engage with Schneider Electric support for guidance and updates on mitigation strategies and patch availability.
