| 제목 | TOTOLINK N300RT Router V3.4.0-B20250430 Buffer Overflow |
|---|
| 설명 | 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 /boafrm/formIpQoS endpoint. Due to the lack of length validation and the use of the unsafe strcpy function, an authenticated attacker can submit a crafted POST request with an oversized entry_name parameter. This overflows a local stack buffer and overwrites the saved return address ($ra), leading to a Denial of Service (DoS) or potential Remote Code Execution (RCE). |
