Official description

D-Link DAP-1325 SetHostIPv6StaticSettings StaticDefaultGateway Stack-based Buffer Overflow Remote Code Execution Vulnerability.

The specific flaw exists within the handling of XML data provided to the HNAP1 SOAP endpoint. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-18834.
