TOTOlink A3002R V1.1.1-B20200824.0128 contains a buffer overflow vulnerability. The vulnerability arises from the improper input validation of the static_gw parameter in the formIpv6Setup interface of /bin/boa.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
