CVE-2025-45379 is an OS command injection vulnerability classified under CWE-78 affecting Dell CloudLink versions prior to 8.2. The flaw arises from improper neutralization of special elements in OS commands executed via the console interface. A privileged user who knows the password can inject malicious commands, leading to arbitrary code execution at the system level. This vulnerability does not require user interaction but does require high privileges, implying that attackers must first obtain or already have privileged credentials. The vulnerability affects confidentiality, integrity, and availability by allowing attackers to execute arbitrary commands, potentially leading to full system compromise, data exfiltration, or service disruption. The CVSS 3.1 base score of 8.4 reflects its high impact and relatively low attack complexity (AC:L). The scope is changed (S:C), indicating that exploitation can affect resources beyond the initially vulnerable component. No public exploits are currently reported, but the vulnerability is publicly disclosed and should be considered critical for environments using affected versions. Dell CloudLink is a security solution often deployed in enterprise and cloud environments, making this vulnerability particularly concerning for organizations relying on it for secure cloud access and management.

For European organizations, the impact of CVE-2025-45379 is significant. Exploitation could lead to unauthorized shell access on critical systems, enabling attackers to manipulate or exfiltrate sensitive data, disrupt services, or move laterally within networks. This is especially critical for sectors such as finance, healthcare, government, and critical infrastructure that rely on Dell CloudLink for secure cloud connectivity. The vulnerability's requirement for privileged credentials means that insider threats or credential compromise scenarios are particularly dangerous. Given the high confidentiality, integrity, and availability impacts, exploitation could result in severe operational disruptions and regulatory compliance violations under GDPR and other frameworks. The lack of known public exploits currently reduces immediate risk but does not diminish the urgency of remediation due to the vulnerability's severity and potential for targeted attacks.

1. Immediately restrict and audit privileged user access to Dell CloudLink consoles to minimize the risk of credential compromise or misuse. 2. Implement multi-factor authentication (MFA) for all privileged accounts to reduce the likelihood of unauthorized access. 3. Monitor and log all console access and command executions for suspicious activity indicative of command injection attempts. 4. Apply principle of least privilege to limit the number of users with high-level access to the CloudLink console. 5. Deploy network segmentation to isolate CloudLink management interfaces from general user networks and the internet. 6. Stay alert for Dell's official patches or updates addressing this vulnerability and apply them promptly once released. 7. Conduct internal penetration testing and vulnerability assessments focusing on CloudLink environments to detect potential exploitation attempts. 8. Educate administrators on the risks of command injection and the importance of secure credential management. 9. Consider temporary compensating controls such as disabling console access if feasible until patches are available.
