# Dairy management system: AJAX endpoint lets remote users read files

A path-manipulation flaw in the checkfarmer.json.php AJAX endpoint of the Dav-ee dairy-management-system lets a remote attacker supply a crafted fname argument. The result is information disclosure, meaning files or data the application should not expose can be read.

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

## How to check

- Check whether the deployment includes `delivery/checkfarmer.json.php` from the repository, e.g. `ls delivery/checkfarmer.json.php`
- Compare the deployed commit against `31ace9692d1e1e6d64339a42c463b361319c615c` or `f31a584c3330c013b61f8b0306d9e0849c6d693d`
- Request the endpoint with an fname value containing `../` and see whether non-application files come back
