CVE-2026-12850— GeoVision GV-I/O Box 4E libNetSetObj.so OS command injection vulnerability

GeoVision GV-I/O Box 4E libNetSetObj.so OS command injection vulnerability

Multiple OS command injection vulnerabilities exist in the libNetSetObj.so functionality of GeoVision GV-I/O Box 4E 2.09. A specially crafted network packet can lead to command execution. An attacker can send a network request to trigger this vulnerability. `libNetSetObj.so` is an internal library used by various binaries on the device to configure the network stack (start and stop various services, configure IP, Netmask, gateway, dns, etc.) #### CNetSetObj::m_F_n_Set_Gate_way command injection The following function takes a string as a gatewy address, performs no sanitization on it and calls `system`. This is a classic command injection vulnerability. The function is reachable from both the network-exposed `DVRSearch` service and the `Network.cgi` endpoint. int __fastcall CNetSetObj::m_F_n_Set_Gate_way(const char **this, char *gw, char *dev) { char s[324]; // [sp+4h] [bp-144h] BYREF if ( !dev && !*this || !gw ) return 0; system("/sbin/route del -net 224.0.0.0 netmask 224.0.0.0"); system("/sbin/route del default "); if ( dev ) sprintf(s, "/sbin/route add default gw %s dev %s", gw, dev); //attacker controlled gw string else sprintf(s, "/sbin/route add default gw %s dev %s", gw, *this); //attacker controlled gw string system(s); sprintf(s, "/sbin/route add -net 224.0.0.0 netmask 224.0.0.0 gw %s dev %s", gw, *this); //attacker controlled gw string system(s); return 1; }
