Cachet vulnerable to forced reinstall
### 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. ### References - https://blog.sonarsource.com/cachet-code-execution-via-laravel-configuration-injection ### For more information If you have any questions or comments about this advisory, you can contact: - The original reporters, by sending an email to vulnerability.research [at] sonarsource.com; - The maintainers, by opening an issue on this repository.
