| 标题 | D-Link Router D-Link DWR-M921 V1.1.52 Command Injection |
|---|
| 描述 | A vulnerability has been found in D-Link DWR-M921 firmware V1.1.52. It can be triggered through the route /boafrm/formSysCmd. The manipulation of the argument sysCmd leads to OS command injection with no filtering whatsoever. The attack is possible remotely after authentication (default admin/admin).
formSysCmd is a hidden handler with no page reference (it does not appear in any .htm form), and was not covered by previously published DWR-M921 CVEs. Unlike other injection points (fota_url prefix check, host ;|& filter), this handler performs no filtering at all, making it the most direct command injection path. It exists only in the /bin/boa dispatch table of V1.1.52 (entry 0x4B9004). |
