| Title | D-Link DWR-M961 V1.1.47 Command Injection |
|---|
| Description | The D-Link DWR-M961 is a 4G LTE router. [cite_start]A command injection vulnerability exists within the firmware (specifically 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.
[cite_start]Consequently, the unsanitized string is passed to the `system()` function, allowing an authenticated attacker to execute arbitrary system commands with root privileges. |
