CVE-2024-49563 is an OS command injection vulnerability identified in Dell Unity storage systems, specifically versions 5.4 and prior. The vulnerability arises due to improper neutralization of special characters in OS commands, classified under CWE-78. This flaw allows a low-privileged attacker who has local access to the system to inject and execute arbitrary operating system commands with root-level privileges. The vulnerability does not require user interaction and has a CVSS v3.1 base score of 7.8, indicating high severity. The attack vector is local (AV:L), with low attack complexity (AC:L), requiring low privileges (PR:L), and no user interaction (UI:N). The scope is unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). Exploiting this vulnerability could lead to full system compromise, including unauthorized data access, data manipulation, or denial of service. No patches or official remediation guidance have been published yet, and no known exploits have been observed in the wild. Dell Unity is widely used in enterprise storage environments, making this vulnerability critical for organizations relying on these systems for data storage and management.

The potential impact of CVE-2024-49563 is severe for organizations using Dell Unity storage systems. Successful exploitation grants attackers root-level access, enabling complete control over the affected system. This can lead to unauthorized data access, data corruption, deletion, or ransomware deployment. The attacker could also use the compromised system as a pivot point to move laterally within the network, escalating the breach's scope. Given the critical role of storage arrays in enterprise IT infrastructure, this vulnerability threatens the confidentiality, integrity, and availability of sensitive data and business operations. Organizations in sectors such as finance, healthcare, government, and critical infrastructure that depend on Dell Unity for data storage face heightened risks of operational disruption and data breaches.

To mitigate CVE-2024-49563, organizations should implement the following specific measures: 1) Restrict local access to Dell Unity systems strictly to trusted administrators and personnel, employing strong physical and logical access controls. 2) Monitor and audit all local access and command executions on Dell Unity devices to detect suspicious activities promptly. 3) Apply the principle of least privilege rigorously, ensuring users have only the minimum necessary permissions to perform their tasks. 4) Segregate management interfaces and storage systems from general user networks to reduce exposure. 5) Engage with Dell support and subscribe to official security advisories to receive patches or workarounds as soon as they become available. 6) Consider deploying host-based intrusion detection systems (HIDS) on management hosts to detect anomalous command executions. 7) Conduct regular security training for administrators to recognize and prevent exploitation attempts. 8) Implement network segmentation and zero-trust principles around critical storage infrastructure to limit lateral movement in case of compromise.
