Technical details
The vulnerability is a command injection flaw in the "set nfs download" CLI command that passes unsanitized user input directly to a system() call, allowing authenticated attackers with services permission to execute arbitrary shell commands as root. Attack requires network access to the CLI interface and valid credentials with services permission. A successful exploit grants complete compromise of the affected device with potential lateral movement to serial-attached downstream devices.
