CVE-2026-12850 is a remote OS command injection vulnerability affecting GeoVision GV-I/O Box 4E version 2.09. The flaw is in the libNetSetObj.so library, specifically the CNetSetObj::m_F_n_Set_Gate_way function used for network stack configuration. The function accepts a gateway address string, incorporates that attacker-controlled value into shell command strings via sprintf, and executes those commands with system() without sanitization or neutralization of shell metacharacters. The vulnerable logic is reachable through the network-exposed DVRSearch service and the Network.cgi endpoint. By supplying a crafted gateway value in a network request or packet, an attacker can cause arbitrary operating system commands to be executed on the device.
