| Título | D-Link DIR-513 1.10 Buffer Overflow |
|---|
| Descripción | The DIR-513 device utilizes the boa program to provide web services. During initialization through the websAspInit function, the program establishes a series of callback APIs. A POST request to the /goform/formSetWanPPPoE path triggers the formSetWanPPPoE callback function, which retrieves the curTime parameter from the request body. This parameter is subsequently processed in the sprintf(v12, "%s?t=%s", last_url, Var); statement, where it gets concatenated into a stack variable. Due to the absence of length validation for curTime, an excessively long input can trigger a stack overflow vulnerability, potentially leading to denial of service. With further exploitation, this vulnerability could enable attackers to obtain shell access. |
