| Titolo | Tenda Router US_W20EV4.0br_V15.11.0.61068_1546_841_CN_TDC Memory Corruption |
|---|
| Descrizione | Tenda W20E contains a stack-based buffer overflow in the formDelDhcpRule handler. The handler copies the attacker-controlled value with the delDhcpIndex parameter into a fixed-size 128-byte stack buffer using strcpy without validating its length. An oversized value causes stack memory corruption and reliably crashes the web management service.
