CVE-2025-30479 is an OS command injection vulnerability identified in Dell CloudLink prior to version 8.2. The root cause is improper neutralization of special elements in OS commands (CWE-78), which allows a privileged user who has authenticated with a known password to inject and execute arbitrary operating system commands on the affected system. This vulnerability is particularly dangerous because it requires only privileged authentication and no additional user interaction, enabling an attacker with legitimate credentials to escalate control over the system. The vulnerability affects the confidentiality, integrity, and availability of the system, as arbitrary commands could lead to data theft, system manipulation, or denial of service. The CVSS v3.1 score is 8.4, reflecting high severity due to the low attack complexity, requirement for privileged access, and the potential for complete system compromise. Although no known exploits are currently reported in the wild, the vulnerability's nature and impact make it a critical concern for organizations relying on Dell CloudLink for cloud security and management. The lack of available patches at the time of reporting necessitates immediate mitigation efforts to reduce exposure.

For European organizations, this vulnerability poses a significant risk to systems running Dell CloudLink, especially those managing sensitive cloud infrastructure or critical services. Successful exploitation could lead to unauthorized command execution, resulting in data breaches, service disruption, or full system takeover. This could affect confidentiality by exposing sensitive data, integrity by allowing unauthorized changes, and availability by causing system outages. Organizations in sectors such as finance, healthcare, government, and critical infrastructure are particularly vulnerable due to the sensitive nature of their data and operations. The requirement for privileged credentials means insider threats or compromised administrative accounts could be leveraged to exploit this vulnerability. Given the interconnected nature of cloud environments, exploitation could also facilitate lateral movement within networks, amplifying the impact across multiple systems and services.

To mitigate this vulnerability, European organizations should immediately restrict and monitor privileged access to Dell CloudLink systems, ensuring that only authorized personnel have administrative credentials. Implement strong password policies and consider multi-factor authentication to reduce the risk of credential compromise. Network segmentation should be employed to limit access to CloudLink management interfaces. Until an official patch or update from Dell is available, consider disabling or limiting features that allow command execution or remote management where feasible. Regularly audit logs for suspicious activity indicative of command injection attempts. Employ application whitelisting and endpoint detection and response (EDR) solutions to detect and block anomalous command execution. Engage with Dell support to obtain updates on patch availability and apply security updates promptly once released. Additionally, conduct security awareness training for administrators to recognize and prevent misuse of privileged credentials.
