DescriptionCVE.org

Hereta ETH-IMC408M firmware version 1.0.15 and prior contain a cross-site request forgery vulnerability that allows attackers to modify device configuration by exploiting missing CSRF protections in setup.cgi. Attackers can host malicious pages that submit forged requests using automatically-included HTTP Basic Authentication credentials to add RADIUS accounts, alter network settings, or trigger diagnostics.

AnalysisAI

Hereta ETH-IMC408M devices running firmware 1.0.15 and earlier are vulnerable to cross-site request forgery attacks that allow unauthenticated remote attackers to modify device configuration through setup.cgi, including adding RADIUS accounts and altering network settings. The vulnerability exploits missing CSRF protections combined with automatic inclusion of HTTP Basic Authentication credentials, requiring only user interaction to trigger the attack. No patch is currently available.

Technical ContextAI

Cross-Site Request Forgery forces authenticated users to perform unintended actions by tricking their browser into sending forged requests. This vulnerability is classified as Cross-Site Request Forgery (CSRF) (CWE-352).
