# DedeCMS: advertisement renderer lets remote attackers inject code via aid

DedeCMS 5.7.118 has a flaw in plus/ad_js.php where the aid argument is not handled safely, enabling code injection. Per the NVD entry, an attacker can trigger it remotely.

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

## How to check

- Confirm the installed DedeCMS version with the site's admin panel or the version file; `unknown` if the sources do not say where it is stored
- Check whether plus/ad_js.php is reachable from the internet on your server

## Fix

- Upgrade DedeCMS to a release later than `5.7.118`; `unknown` if the sources name a fixed version
- Restrict or remove access to plus/ad_js.php until patched

## Timeline
