Authenticated memory corruption via index handling
Published Jan 15, 2024 · Updated Jun 9, 2025
Stack-based buffer overflow in httpd in Shenzhen Tenda Technology W9 1.0.0.7(4456) allows remote authenticated users to corrupt memory. Public records establish that manipulating index in formWifiMacFilterGet overflows its stack buffer but do not disclose the exact copy operation or buffer size. Low-privileged access to the network-reachable httpd interface is required, and successful exploitation can corrupt process control data or interrupt the service.
