**Name of the Vulnerable Software and Affected Versions**
SmartNode SN200 (aka SN200) version 3.21.2-23021
**Description**
The issue is related to the Network Diagnostic Commands function of the SmartNode SN200 analog telephone adapter's firmware, which fails to neutralize special elements used in an operating system command.
