How the CVE Works
CVE-2025-6146 is a critical buffer overflow vulnerability in TOTOLINK X15 firmware version 1.0.0-B20230714.1105. The flaw exists in the HTTP POST request handler within the `/boafrm/formSysLog` endpoint. Attackers can exploit this by sending a specially crafted POST request with an oversized `submit-url` argument, overflowing the buffer and potentially allowing remote code execution. The vulnerability is remotely exploitable, and public disclosure increases the risk of active exploitation.
