CVE-2024-0571Network attack vector

Authenticated stack overflow via crafted SMS text

Published Jan 16, 2024 · Updated Jun 17, 2025

Stack-based buffer overflow in TOTOLINK LR1200GB 9.1.0u.6619_B20230130 allows remote authenticated users to corrupt process memory. The setSmsCfg function in /cgi-bin/cstecgi.cgi processes a crafted text argument into a stack buffer, but published sources do not disclose the exact copy operation or boundary failure. A valid management session is required, and the public record does not establish whether successful exploitation causes code execution, a crash, or both.
