Submit #777616: Tenda AC6 AC6 V1.0 V15.03.05.16 Buffer Overflowinfo

TitleTenda AC6 AC6 V1.0 V15.03.05.16 Buffer Overflow
DescriptionThe Tenda AC6 V1.0 V15.03.05.16 firmware has a stack overflow vulnerability located in the fromWizardHandle function. This function accepts the WANTand WANS parameter from a POST request. Within case 2, this function accepts the PPW parameter from a POST request, which is assigned to decodePwd(pppoepwd, decode_pwd);. However, since the user has control over the input of PPW, the function decodePwd() leads to a buffer overflow. The user-supplied PPW can exceed the capacity of the decode_pwd array, thus triggering this security vulnerability.
