CVE-2018-5455

A Reliance on Cookies without Validation and Integrity Checking issue was discovered in Moxa OnCell G3100-HSPA Series version 1.4 Build 16062919 and prior. The application allows a cookie parameter to consist of only digits, allowing an attacker to perform a brute force attack bypassing authentication and gaining access to device functions.
