CVE-2025-2370Public exploitNetwork attack vector

Authenticated memory corruption via crafted Wi-Fi SSID

Published Mar 17, 2025 · Updated Mar 17, 2025

Stack-based buffer overflow in TOTOLINK EX1800T 9.1.0cu.2112_B20220316 allows remote authenticated users to corrupt device memory. The setWiFiExtenderConfig handler in /cgi-bin/cstecgi.cgi accepts an attacker-controlled apcliSsid value, but the exact unsafe copy operation is undisclosed. Low-privileged network access is required, and public sources do not specify the concrete post-overflow effect.
