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 execute system commands remotely, potentially gaining control over the device and access to the local network.
Recommendation
It is recommended to update the software to the latest version that addresses these vulnerabilities and to 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_Gate_way command injection The 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. int __fastcall CNetSetObj::m_F_n_Set_Gate_way(const char **this, char *gw, char *dev) { char s[324]; // [sp+4h] [bp-144h] BYREF if ( !dev && !*this || !gw ) return 0; system("/sbin/route del -net 224.0.0.0 netmask 224.0.0.0"); system("/sbin/route del default "); if ( dev ) sprintf(s, "/sbin/route add default gw %s dev %s", gw, dev); //attacker controlled gw string else sprintf(s, "/sbin/route add default gw %s dev %s", gw, *this); //attacker controlled gw string system(s); 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 system(s); return 1; }
