    "description": "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.\n\n\n`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.)\n\n\n#### CNetSetObj::m_F_n_Set_Gate_way command injection\n\nThe 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. \n\n\n\n\n\n    int __fastcall CNetSetObj::m_F_n_Set_Gate_way(const char **this, char *gw, char *dev)\n\n    {\n\n      char s[324]; // [sp+4h] [bp-144h] BYREF\n\n\n\n      if ( !dev && !*this || !gw )\n\n        return 0;\n\n      system(\"/sbin/route del -net 224.0.0.0 netmask 224.0.0.0\");\n\n      system(\"/sbin/route del default \");\n\n      if ( dev )\n\n        sprintf(s, \"/sbin/route add default gw %s dev %s\", gw, dev); //attacker controlled gw string\n\n      else\n\n        sprintf(s, \"/sbin/route add default gw %s dev %s\", gw, *this); //attacker controlled gw string\n\n      system(s);\n\n      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\n\n      system(s);\n\n      return 1;\n\n      }",
