CVE-2024-49564 is an OS command injection vulnerability identified in Dell Unity storage systems, specifically versions 5.4 and prior. The root cause is improper neutralization of special elements used 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, effectively enabling privilege escalation and full system compromise. 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) and low privileges required (PR:L). The scope remains unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). While no public exploits have been reported yet, the potential for exploitation is significant due to the severity and ease of exploitation once local access is obtained. The vulnerability affects Dell Unity storage arrays, which are widely used in enterprise data centers for storage management and data protection. Exploitation could lead to unauthorized data access, data manipulation, or disruption of storage services, severely impacting organizational operations.

The impact of CVE-2024-49564 is substantial for organizations using Dell Unity storage systems. Successful exploitation allows attackers to gain root privileges, leading to complete control over the affected storage system. This can result in unauthorized access to sensitive data, data corruption or deletion, and disruption of critical storage services. Enterprises relying on Dell Unity for data storage and backup could face significant operational downtime, data breaches, and compliance violations. The elevated privileges also enable attackers to pivot to other parts of the network, increasing the risk of broader compromise. Given the critical role of storage infrastructure in IT environments, the vulnerability poses a high risk to confidentiality, integrity, and availability of enterprise data. Organizations in sectors such as finance, healthcare, government, and telecommunications, where data integrity and availability are paramount, are particularly at risk.

To mitigate CVE-2024-49564, organizations should implement the following specific measures: 1) Immediately restrict local access to Dell Unity systems to trusted administrators only, using strong authentication and access controls. 2) Monitor system logs and command execution patterns for unusual or unauthorized activity indicative of command injection attempts. 3) Apply principle of least privilege by limiting user permissions on the storage system to the minimum necessary. 4) Prepare for rapid deployment of official patches or firmware updates from Dell once released; engage with Dell support channels to obtain timelines and interim fixes. 5) Employ network segmentation to isolate storage systems from general user networks, reducing the risk of local access by unauthorized users. 6) Conduct regular security audits and vulnerability assessments on storage infrastructure to detect and remediate potential weaknesses. 7) Educate administrators on the risks of local access vulnerabilities and enforce strict operational security policies. These steps go beyond generic advice by focusing on access restriction, monitoring, and preparation for patching specific to Dell Unity environments.
