TitleEdimax BR6478ACV2 BR6478ACV2_v1.23 Buffer Overflow
DescriptionThe EDIMAX BR6478ACV2_v1.23 firmware has a stack overflow vulnerability in the formL2TPSetup function. The v108 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.
