### Summary The application contains a reflected cross-site scripting via URL-parameter `?k304=...` and `?setck=...` ### Details A reflected cross-site scripting (XSS) vulnerability exists in the web interface of the application that could allow an attacker to execute malicious javascript code by tricking users into accessing a malicious link. The worst-case outcome of this is being able to move or delete existing files on the server, or upload new files, using the account of the person who clicks the malicious link. It is recommended to change the passwords of your copyparty accounts, unless you have inspected your logs and found no trace of attacks. ### Checking for exposure if copyparty is running behind a reverse proxy, you can check the access-logs for traces of attacks, by grepping for URLs containing `?hc=` with `<` somewhere in its value, for example using the following command: * nginx: ```bash (gzip -dc access.log*.gz; cat access.log) | sed -r 's/" [0-9]+ .*//' | grep...

### Impact Authenticated users can inject malicious code in widgets with units, which is then executed both in the element preview (back end) and on the website (front end). ### Patches Update to Contao 4.9.42, 4.13.28 or 5.1.10. ### Workarounds Disable login for all untrusted back end users. ### References https://contao.org/en/security-advisories/cross-site-scripting-in-widgets-with-units ### For more information If you have any questions or comments about this advisory, open an issue in [contao/contao](https://github.com/contao/contao/issues/new/choose). ### Credits Thanks to Maximilian Seilmaier from usd AG for reporting this vulnerability.
