| Title | Tenda AC9 AC9 V1.0 V15.03.02.13 Buffer Overflow |
|---|
| Description | In Tenda AC9 V1.0 V15.03.02.13 firmware has a stack overflow vulnerability in the addWifiMacFilter function. The device_mac variable receives the deviceMac parameter from a POST request. The value is directly used in a sprintf function and passes to a local variable on the stack, which can override the return address of the function. The user-provided deviceMac can trigger this security vulnerability. |
