| Title | EDIMAX EW-7478APC EW-7478APC 1.04 Buffer Overflow |
|---|
| Description | The EDIMAX EW-7478APC 1.04 firmware has a stack overflow vulnerability in the formWanTcpipSetup function. The v163 variable receives the pppUserName parameter from a POST request. However, since the user can control the input of pppUserName, the statement strcat() can cause a buffer overflow. |
