Enviar #746400: D-Link DWR-M921 V1.1.50 Command Injectioninformación

TítuloD-Link DWR-M921 V1.1.50 Command Injection
DescripciónDuring a security review of the D-Link DWR-M921 router firmware, a critical command injection vulnerability was identified in the USSD configuration endpoint `/boafrm/formUSSDSetup`. The vulnerability exists within the `sub_419F20` function. This function retrieves the user-controlled parameter `ussdValue` and uses `sprintf` to inject it directly into a system command string associated with the `at-mngr` utility. The resulting string is passed to the `system()` function without sufficient sanitization of single quotes, allowing authenticated attackers to break out of the command structure and execute arbitrary OS commands with root privileges.
