CVE-2025-22398 is a critical OS command injection vulnerability affecting Dell Unity, Dell UnityVSA, and Dell Unity XT running Dell Unity Operating Environment versions earlier than 5.5.0.0.5.259, including 5.4 and prior. The flaw is caused by improper neutralization of special elements used in operating system commands, allowing attacker-controlled input to be incorporated into OS-level command execution. A remote unauthenticated attacker can exploit the issue to execute arbitrary system commands with root privileges on the underlying appliance. Because exploitation yields root-level command execution on the storage system, the vulnerability can result in complete operating system compromise and full takeover of the affected device.
