CVE-2019-12254

Severity CVSS v4.0:
Pending analysis
Type:
CWE-287 Authentication Issues
Publication date:
06/05/2022
Last modified:

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.
