| タイトル | Tenda W3 V1.0.0.3(2204) Buffer Overflow |
|---|
| 説明 | A stack-based buffer overflow exists in Tenda w3 V1.0.0.3(2204). The HTTP handler formSetCfm reads the POST parameter funcpara1 from the /goform/setcfm endpoint and copies it into a fixed-length stack buffer without proper bounds checking. By sending an overlong funcpara1, an unauthenticated attacker on the LAN can overwrite the stack, corrupting the return address and leading to a crash or potential code execution. The issue is triggered in the request parsing path for funcname=save_list_data with a long funcpara1 payload. |
