| Titel | YZNCMS 2.1.5 SQL Injection |
|---|
| Beschreibung | YZNCMS v2.1.5 allows a super administrator to upload and install a local addon package when `APP_DEBUG=true`. The addon installation flow extracts attacker-controlled ZIP content and then enables the addon, copying addon asset files into a web-accessible directory under `public/assets/addons/<name>/`.
Because the upload flow does not restrict executable PHP content inside the addon package, a super administrator can upload an addon containing a PHP payload and obtain remote code execution.
Affected code paths:
- `app/admin/controller/Addon.php:273`
- `vendor/yzncms/think-addons/src/addons/Service.php:391`
- `vendor/yzncms/think-addons/src/addons/Service.php:584`
- `vendor/yzncms/think-addons/src/addons/Service.php:204`
- `vendor/yzncms/think-addons/src/addons/Service.php:870` |
