    "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_DNS_Addr command injection\n\nThe following function can take up to two addresses, performs no sanitization and then 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    int __fastcall CNetSetObj::m_F_n_Set_DNS_Addr(CNetSetObj *this, char *dns1, char *dns2)\n\n    {\n\n      int result; // r0\n\n      char v5[80]; // [sp+0h] [bp-50h] BYREF\n\n\n\n      if ( !dns1 )\n\n        result = 0;\n\n      if ( dns1 )\n\n      {\n\n        sprintf(v5, \"/bin/echo nameserver %s > /etc/resolv.conf\", dns1);  // attacker controlled dns1 field\n\n        system(v5);\n\n        if ( dns2 )\n\n        {\n\n          sprintf(v5, \"/bin/echo nameserver %s >> /etc/resolv.conf\", dns2);\n\n          system(v5);\n\n        }\n\n        return 1;\n\n      }\n\n      return result;",
