| 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)..
The issue lies in the handling of the `fota_url` parameter within the `/boafrm/formLtefotaUpgradeFibocom` endpoint. The firmware fails to properly sanitize user-supplied input before passing it to a system command wrapper (likely via `sprintf` and `system`). This allows an authenticated attacker to inject arbitrary shell commands by appending them to the URL parameter.
