# Modoboa: authenticated users can delete other domains' alarms

Modoboa before 2.8.0 lets any authenticated user delete monitoring alarms belonging to other domains through the POST /api/v2/alarms/bulk_delete/ endpoint. An attacker can enumerate sequential alarm IDs to wipe DNS, MX and blocklist alarms server-wide, hiding problems from administrators.

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

## How to check

- Check the installed Modoboa version (`pip show modoboa` or the deployed package) and see whether it is below `2.8.0`
- Confirm whether untrusted or low-privilege user accounts exist on the instance

## Fix

- Upgrade Modoboa to `2.8.0` or later
- Review alarm history for deletions that were not made by administrators

## From the sources

Modoboa before 2.8.0 contains an insecure direct object reference vulnerability that allows authenticated users to delete alarms of other domains via the POST /api/v2/alarms/bulk_delete/ action. Attackers can enumerate sequential alarm IDs to delete DNS, MX and blocklist monitoring alarms server-wide, hiding problems from responsible administrators.
