| Título | D-Link DIR-825 C1_FW3.00b32 Buffer Overflow |
|---|
| Descrição | A stack-based buffer overflow exists in the `miniupnpd` implementation used by D-Link DIR-825. The issue is reachable through the LAN-side UPnP SOAP interface during `AddPortMapping` processing.
An attacker on the local network can send a crafted `AddPortMapping` request with an oversized `NewPortMappingDescription` value. When the request updates an existing port mapping, the description is written to a fixed-size stack buffer via `sprintf()` without length validation, leading to memory corruption. |
