GeoVision GV-I/O Box 4E libNetSetObj.so OS command injection vulnerability_CVE-2026-12486

{
    "lastseen": "",
    "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_IP_Addr command injection\n\nThe following function takes a string as an ip address, performs no sanitization 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    int __fastcall CNetSetObj::m_F_n_Set_IP_Addr(const char **this, char *ip_addr)\n\n    {\n\n      bool v2; // zf\n\n      char v4[72]; // [sp+0h] [bp-48h] BYREF\n\n\n\n      v2 = *this == 0;\n\n      if ( *this )\n\n        v2 = ip_addr == 0;\n\n      if ( v2 )\n\n        return 0;\n\n      sprintf(v4, \"/sbin/ifconfig %s %s\", *this, ip_addr);  // attacker controlled ip address \n\n      system(v4);\n\n      return 1;\n\n    }",
