| Название | Totolink N300RT Router V3.4.0-B20250430 Buffer Overflow |
|---|
| Описание | A stack-based buffer overflow vulnerability exists in the boa web server of the TOTOLINK N300RT router (firmware <= V3.4.0-B20250430). The vulnerability is located in the is_cmd_string_valid function within libapmib.so, which fails to validate the length of the localPin parameter in the /boafrm/formWsc endpoint. An authenticated attacker can bypass CSRF and token checks to send a crafted POST request with an oversized payload. This overflows a local buffer and overwrites the saved return address ($ra), leading to a Denial of Service (DoS) or potential Remote Code Execution (RCE). |
