RE11S_1.11-formiNICbasicREP-StackOverflow

During my internship at Qi An Xin Tiangong Lab, I discovered a stack overflow vulnerability in the RE11S_1.11 router.

By analyzing the webs file in the bin directory, I found that the function formiNICbasicREP contains a stack overflow vulnerability.

The stack overflow can be triggered by the rootAPmac key value, which leads to a sprintf stack overflow.
