| Titre | D-Link DWR-M920 1.1.50 Command Injection and Stack Buffer Overflow |
|---|
| Description | The /boafrm/formIMEISetup handler in the boa web server contains five independent OS command injection vulnerabilities and one stack buffer overflow, all reachable through the IMEI_value POST parameter. The parameter is read from the HTTP request and passed directly into sprintf() with an AT command format string, then executed via system() — without any sanitization, filtering, or length validation.
Each injection path is gated by a MIB module/lookup ID pair (sub_412DA0), which identifies the installed modem module (Quectel, Fibocom, Gosuncn, etc.). On a device with a supported modem, the matching path activates and the attacker-supplied IMEI_value flows into the shell. |
