What is CVE-2019-12254?
CVE-2019-12254 is a critical missing authorization vulnerability in GOK LX-Net, published on 6 May 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
Weakness: CWE-287
