| Title | D-Link Router DIR823G_V1.0.2B05_20181207 Memory Corruption |
|---|
| Description | D-Link DIR-823G contains a stack-based buffer overflow in the HNAP1 SetStaticRouteSettings handler. The handler copies the attacker-controlled XML value into a fixed-size 32-byte stack buffer using strcpy without validating its length. An oversized value causes stack memory corruption and reliably crashes the web management service. |
