No affected components available
A time-of-create-to-time-of-use (TOCTOU) vulnerability lets recently deleted-then-recreated data sources be re-deleted without permission to do so.
This requires several very stringent conditions to be met:
- The attacker must have admin access to the specific datasource prior to its first deletion.
- Upon deletion, all steps within the attack must happen within the next 30 seconds and on the same pod of Grafana.
- The attacker must delete the datasource, then someone must recreate it.
- The new datasource must not have the attacker as an admin.
- The new datasource must have the same UID as the prior datasource. These are randomised by default.
- The datasource can now be re-deleted by the attacker.
- Once 30 seconds are up, the attack is spent and cannot be repeated.
- No datasource with any other UID can be attacked.
