# D-Link DCS-930L Devices: D-Link DCS-930L Devices OS Command Injection Vulnerability

D-Link DCS-930L network cameras have an OS command injection in the setSystemCommand function, so a remote attacker can run commands on the device. CISA lists it as actively exploited in the wild.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:D-Link DCS-930L Devices affected ? fixed ?

## Fix

The product is end-of-life and no vendor fix is named in the sources; disconnect the device from the network if still in use.

## From the sources

setSystemCommand on D-Link DCS-930L devices allows a remote attacker to execute code via an OS command.

CISA required action: The impacted product is end-of-life and should be disconnected if still in use.
