| Description | Totolink 路由器中的堆栈溢出漏洞
1. The vulnerability entry point is the regular processing logic of HTTP request headers in `http_request_parse`.
2. The value of the `Host` field will be extracted and passed into `find_host_ip`.
3. The `find_host_ip` function lacks strict length constraints during the replication process.
4. The small stack buffer (`char v113[32]`) used by the caller can be overwritten by overly long data, posing a risk of stack corruption.
5. In this firmware and experimental configuration, when the length of 'Host' reaches 512+, it can reliably trigger a service exception or crash. |
