CVE-2024-49563
Published: 28 March 2025
Description
Adversaries may abuse Unix shell commands and scripts for execution.
Security Summary
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.
