CVE-2025-68706 Details
Description
A stack-based buffer overflow exists in the GoAhead-Webs HTTP daemon on KuWFi 4G LTE AC900 devices with firmware 1.0.13. The /goform/formMultiApnSetting handler uses sprintf() to copy the user-supplied pincode parameter into a fixed 132-byte stack buffer with no bounds checks. This allows an attacker to corrupt adjacent stack memory, crash the web server, and (under certain conditions) may enable arbitrary code execution.
A stack-based buffer overflow vulnerability has been identified in the GoAhead-Web HTTP daemon running on KuWFi 4G LTE AC900 devices with firmware 1.0.13. The issue arises in the '/goform/formMultiApnSetting' handler, where the user-supplied 'pincode' parameter is copied into a fixed 132-byte stack buffer using 'sprintf()' without proper bounds checking. This vulnerability allows attackers to overwrite adjacent stack memory, potentially leading to a crash of the web server and, under certain conditions, arbitrary code execution.
