CVE-2025-68706
CriticalSummary
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.
Risk Assessment
An attacker can corrupt adjacent stack memory, crash the web server, and under certain conditions may enable arbitrary code execution, potentially leading to full device compromise.
Recommendation
Update the device firmware to a patched version or restrict access to the admin panel and apply input filtering.
Original NVD description (English source)
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.
