VLAI
Summary
Cachet vulnerable to forced reinstall
Details

Impact

Authenticated users, regardless of their privileges (User or Admin), can trick Cachet and install the instance again, leading to arbitrary code execution on the server.

Patches

This issue was addressed by improving the middleware ReadyForUse, which now performs a stricter validation of the instance name.

Workarounds

Only allow trusted source IP addresses to access to the administration dashboard.
