| Título | D-Link DW V1.1.47 Command Injection |
|---|
| Descripción | A command injection vulnerability exists in the D-Link DWR-M961 4G LTE router firmware within the SMS management functionality.
The vulnerability is located in the function `sub_41A488` (referenced by `sub_4250E0`), which is invoked when the `/boafrm/formSmsManage` endpoint receives a request with the parameter `action_id` set to `"delete"`.
The function retrieves the `action_value` parameter (representing SMS message IDs to delete) and uses it to construct a system command via `sprintf`:
`sprintf(v7, "at-mngr AT+CMGD=%s", i);`
The variable `i` (derived from `action_value` via `strtok`) is not sanitized. The resulting string `v7` is passed directly to `system()`. This allows an authenticated attacker to append arbitrary shell commands using a semicolon (`;`) or other shell metacharacters. |
