## Technical details

An OS command injection vulnerability exists in the SonicWall NSM On-Prem management interface due to improper neutralization of special characters in OS commands. The vulnerability resides in the management interface processing logic and requires the attacker to be authenticated with SuperAdmin privileges to exploit it. An authenticated attacker can inject arbitrary shell commands that are executed with the privileges of the NSM process on the underlying host, achieving unauthenticated remote code execution. The vulnerability likely stems from unsafe command construction or shell metacharacter handling in the administrative API or management console.
