CVE-2025-46365 is a command injection vulnerability identified in Dell CloudLink versions prior to 8.1.1. The vulnerability stems from improper neutralization of special elements used in system commands (CWE-77), allowing an authenticated attacker with high privileges to inject arbitrary commands into the system. The attack vector is local (AV:L), requiring the attacker to have authenticated access with high privileges (PR:H) and no user interaction (UI:N). The vulnerability affects the integrity of the system by enabling execution of unauthorized commands, but does not impact confidentiality or availability directly. The attack complexity is high (AC:H), meaning exploitation requires specific conditions or knowledge, limiting ease of exploitation. The vulnerability has a CVSS v3.1 base score of 5.3, categorized as medium severity. No patches or known exploits are currently available, but the vulnerability’s presence in a cloud security product used to protect virtualized environments and cloud workloads makes it a significant concern. Attackers exploiting this vulnerability could manipulate system configurations or escalate privileges further, potentially compromising the security posture of affected environments. The vulnerability’s scope is changed (S:C), indicating that exploitation could affect resources beyond the initially vulnerable component, increasing the risk profile. Given the nature of Dell CloudLink as a cloud security platform, this vulnerability could impact cloud infrastructure security management if exploited.

For European organizations, the impact of CVE-2025-46365 could be significant in environments relying on Dell CloudLink for cloud security and workload protection. Successful exploitation could allow attackers to execute arbitrary commands with high privileges, potentially leading to unauthorized changes in system configurations, deployment of malicious code, or lateral movement within cloud environments. This undermines the integrity of critical cloud infrastructure and could lead to further compromise of sensitive data or disruption of cloud services. Although confidentiality and availability are not directly impacted, the integrity breach could facilitate subsequent attacks that affect these aspects. Organizations in sectors such as finance, government, and critical infrastructure, which often use cloud security solutions like Dell CloudLink, face increased risk. The requirement for authenticated high-privilege access reduces the likelihood of opportunistic attacks but raises concerns about insider threats or compromised credentials. The absence of patches increases exposure time, necessitating proactive risk management. Additionally, the vulnerability’s potential to affect multiple components within cloud environments could amplify its impact if exploited.

To mitigate CVE-2025-46365, European organizations should implement the following specific measures: 1) Restrict access to Dell CloudLink management interfaces strictly to trusted administrators using network segmentation and firewall rules to minimize exposure. 2) Enforce strong authentication mechanisms, including multi-factor authentication (MFA), to reduce the risk of credential compromise for high-privilege accounts. 3) Apply the principle of least privilege by limiting user permissions to only those necessary for their roles, thereby reducing the attack surface. 4) Monitor logs and command execution activities within CloudLink environments for anomalous behavior indicative of command injection attempts. 5) Maintain an inventory of Dell CloudLink versions deployed and prepare for timely patching once vendor updates become available. 6) Conduct regular security assessments and penetration testing focused on cloud management platforms to identify and remediate potential weaknesses. 7) Educate administrators on the risks of command injection vulnerabilities and best practices for secure configuration. 8) Consider deploying application-layer firewalls or intrusion detection systems capable of detecting command injection patterns targeting CloudLink interfaces. These targeted actions go beyond generic advice and address the specific nature and context of this vulnerability.
