CVE-2024-0575Network attack vector

Memory corruption via command stack overflow

Published Jan 16, 2024 · Updated Sep 10, 2024

Stack-based buffer overflow in TOTOLINK LR1200GB 9.1.0u.6619_B20230130 allows remote authenticated users to corrupt process memory. The setTracerouteCfg handler in /cgi-bin/cstecgi.cgi lets the HTTP command argument overrun a stack buffer; the exact copy operation is undisclosed. A reachable management interface and low-privilege authentication are required; the published record does not establish code execution.
