Buffer Overflow vulnerability in Shenzhen Libituo Technology Co., Ltd LBT-T300-T400 v.3.2 allows a local attacker to execute arbitrary code via the vpn_client_ip variable of the config_vpn_pptp function in rc program.
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.
