Technical 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.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
