|---|
| Description | Tenda W20E firmware US_W20EV4.0br_V15.11.0.61068_1546_841_CN_TDC contains a stack-based buffer overflow in the formIPMacBindModify HTTP handler. The handler retrieves the attacker-controlled IPMacBindRuleIp、IPMacBindRuleMac、IPMacBindRuleRemark parameters using websGetVar() and copies it into the fixed-size stack buffer using sprintf() without length validation. Values of more characters overwrite adjacent stack memory and reliably crash the web management service. The confirmed impact is denial of service. |
