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 IP Addr command injection
The 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.int fastcall CNetSetObj::m F n Set IP Addr(const char **this, char *ip addr)
{
bool v2; // zf
char v4[72]; // [sp+0h] [bp-48h] BYREF
v2 = *this == 0;
if ( *this )
v2 = ip addr == 0;if ( v2 )
return 0;sprintf(v4, "/sbin/ifconfig %s %s", *this, ip addr); // attacker controlled ip address
system(v4);
return 1;
}
