Summary
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.
Risk Assessment
An attacker can exploit this vulnerability to remotely execute commands on the device, potentially leading to severe security breaches and loss of control over the system.
Recommendation
It is recommended to update the software to the latest version that addresses these vulnerabilities and implement appropriate security measures such as network traffic filtering.
Original NVD description (English source)
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_Net_Mask command injection The following function takes a string as a net mask 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_Net_Mask(const char **this, char *netmask_addr) { bool v2; // zf char v4[72]; // [sp+0h] [bp-48h] BYREF v2 = *this == 0; if ( *this ) v2 = netmask_addr == 0; if ( v2 ) return 0; sprintf(v4, "/sbin/ifconfig %s netmask %s", *this, netmask_addr); // attacker controlled netmask_addr system(v4); return 1; }
