# D-Link DNS-320 Storage Device: D-Link DNS-320 Remote Code Execution Vulnerability

The login_mgr.cgi script on the D-Link DNS-320 NAS lets a remote attacker execute code on the device. CISA lists it as actively exploited, and the source tags it as used in ransomware campaigns.

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

## Affected

- vendor:D-Link DNS-320 Storage Device affected ? fixed ?

## How to check

Check whether any DNS-320 device is on your network or reachable from the internet; the sources do not give a firmware version or file check.

## Fix

Disconnect the DNS-320 from the network; CISA says the product is end-of-life and no patch is named in the sources.
Replace the device with a supported NAS model.
