| Название | D-Link DWR-M921 V1.1.50 Command Injection |
|---|
| Описание | During a security review of the D-Link DWR-M921 router firmware, a critical command injection vulnerability was identified in the `/bin/boa` binary).
[cite_start]The vulnerability is located in the function `sub_419920` (as identified in IDA Pro), which handles requests for the `/boafrm/formLtefotaUpgradeQuectel` endpoint. The function retrieves the `fota_url` parameter from the user input. [cite_start]While it checks if the input contains "http://", "https://", or "ftp://", it fails to strictly filter or sanitize the string before passing it to `sprintf` to construct a shell command. |
