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    }"

Un paquete de red especialmente diseñado puede llevar a la ejecución de comandos. Un atacante puede enviar una solicitud de red para activar esta vulnerabilidad.\n\n’libNetSetObj.so’ es una biblioteca interna utilizada por varios binarios en el dispositivo para configurar la pila de red (iniciar y detener varios servicios, configurar dirección IP, máscara de red, puerta de enlace, DNS, etc.).\n\n#### Inyección de comandos CNetSetObj::m_F_n_Set_IP_Addr\n\nLa siguiente función toma una cadena como una dirección IP, no realiza ninguna sanitización y llama a ’system’.

La función es accesible tanto desde el servicio ’DVRSearch’ expuesto en la red como desde el endpoint ’Network.cgi’.\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);  // dirección IP controlada por el atacante\n\n      system(v4);\n\n      return 1;\n\n    }"
