Published: 28 March 2025
Summary
CVE-2024-49563 is a high-severity OS Command Injection (CWE-78) vulnerability in Dell Unity Operating Environment. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 48.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
SI-2 requires organizations to identify, report, and correct flaws like this OS command injection vulnerability through timely patching, such as Dell's DSA-2025-116 update.
SI-10 enforces validation of system inputs to detect and reject improperly neutralized special elements, directly preventing OS command injection exploitation.
AC-6 applies least privilege to restrict low-privileged local accounts from accessing vulnerable components, limiting the potential for privilege escalation even if injection occurs.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
OS command injection allows local low-privileged users to execute arbitrary commands as root, directly enabling T1068 (Exploitation for Privilege Escalation) and T1059.004 (Unix Shell) for command execution on the Linux-based Dell Unity system.

Deeper analysisAI
CVE-2024-49563 is an Improper Neutralization of Special Elements used in an OS Command, known as an OS Command Injection vulnerability (CWE-78), affecting Dell Unity versions 5.4 and prior. This flaw allows special elements in OS commands to be inadequately sanitized, enabling malicious input to alter command execution.
A low-privileged attacker with local access can exploit this vulnerability to execute arbitrary operating system commands with root privileges, leading to privilege escalation. The CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) reflects high impacts on confidentiality, integrity, and availability in a local attack scenario with low complexity and no user interaction required.
Dell has published DSA-2025-116, a security update addressing this vulnerability along with multiple others in Dell Unity, Dell UnityVSA, and Dell Unity XT, available at https://www.dell.com/support/kbdoc/en-us/000300090/dsa-2025-116-security-update-for-dell-unity-dell-unityvsa-and-dell-unity-xt-security-update-for-multiple-vulnerabilities.
