CVE-2019-12254
TECSON/GOK: Improper Authentication and Access Control on multiple devices
- Published
- Updated
- Reserved
- Assigned by
- CERTVDE
Description
In multiple Tecson Tankspion and GOKs SmartBox 4 products the affected application doesn't properly restrict access to an endpoint that is responsible for saving settings, to a unauthenticated user with limited access rights. Based on the lack of adequately implemented access-control rules, by accessing a specific uniform resource locator (URL) on the web server, a malicious user is able to change the application settings without authenticating at all, which violates originally laid ACL rules.
