| Title | EDIMAX BR-6428NS BR-6428NS_v4_1.10 Buffer Overflow |
|---|
| Description | The EDIMAX BR-6428NS_v4_1.10 firmware has a stack overflow vulnerability in the formL2TPSetup function. The v22 variable receives the L2TPUserName parameter from a POST request. However, since the user can control the input of L2TPUserName, the statement strcat() can cause a buffer overflow. |
