CVE-2021-43589

Privilege elevation via undisclosed OS command injection

Published Jan 24, 2022 · Updated Sep 17, 2024

OS command injection in Dell Unity before 5.1.2.0.5.007 allows local users with high privileges to execute arbitrary OS commands. Dell has not disclosed the proprietary-code locus, attacker-controlled input, or unsafe command-construction operation. Exploitation requires local high-privilege authentication and runs commands with the vulnerable application's privileges, enabling privilege elevation and system alteration or interruption.
