Buffer overflow vulnerability in Digital China DCBI-Netlog-LAB Gateway 1.0 due to the lack of length verification, which is related to saving parental control configuration information. Attackers who successfully exploit this vulnerability can cause the remote target device to crash or execute arbitrary commands.
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.
