CVE-2024-3910Network attack vector

Authenticated memory corruption via crafted page parameter

Published Apr 17, 2024 · Updated Aug 1, 2024

Stack-based buffer overflow in Tenda AC500 2.0.1.9(1307) allows remote authenticated users to corrupt memory via a crafted page parameter. The fromDhcpListClient handler for /goform/DhcpListClient processes the parameter in a way that overruns a stack buffer; the exact copy operation and buffer size are undisclosed. Low-privilege web-interface access is required, and the public record establishes memory corruption but not reliable code execution.
