CVE-2025-43943 is an OS Command Injection vulnerability identified in Dell Cloud Disaster Recovery versions prior to 19.20. This vulnerability arises from improper neutralization of special elements used in operating system commands (CWE-78). Specifically, the flaw allows a high-privileged attacker with local access to execute arbitrary commands with root privileges on the affected system. The vulnerability requires local access and high privileges to exploit, and no user interaction is needed once the attacker has the required access. The CVSS v3.1 base score is 6.7, indicating a medium severity level. The attack vector is local (AV:L), with low attack complexity (AC:L), requiring high privileges (PR:H), and no user interaction (UI:N). The impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H), meaning successful exploitation could lead to full system compromise, including unauthorized data access, modification, and service disruption. No known exploits are currently reported in the wild, and no patches or mitigation links have been provided yet. The vulnerability affects Dell Cloud Disaster Recovery, a product used for cloud-based backup and disaster recovery solutions, which is critical for business continuity and data protection.

For European organizations, this vulnerability poses a significant risk, especially for enterprises relying on Dell Cloud Disaster Recovery for their backup and disaster recovery operations. Exploitation could lead to complete system compromise, allowing attackers to execute arbitrary commands with root privileges, potentially resulting in data breaches, loss of data integrity, and disruption of disaster recovery services. This could severely impact organizations' ability to recover from incidents, leading to extended downtime and regulatory compliance issues, particularly under GDPR requirements for data protection and breach notification. The requirement for local high-privileged access limits the attack surface but insider threats or attackers who have already gained elevated access could leverage this vulnerability to escalate privileges further and compromise critical infrastructure.

European organizations should prioritize upgrading Dell Cloud Disaster Recovery to version 19.20 or later once available to address this vulnerability. Until a patch is released, organizations should enforce strict access controls to limit local high-privileged access to trusted personnel only. Implementing robust monitoring and auditing of privileged user activities can help detect suspicious behavior indicative of exploitation attempts. Network segmentation and the use of endpoint protection solutions can reduce the risk of attackers gaining local access. Additionally, organizations should review and harden their disaster recovery environment configurations, ensuring minimal privilege principles are applied. Regular vulnerability assessments and penetration testing focusing on privilege escalation vectors can help identify and mitigate related risks proactively.
