Severity
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. 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_DNS_Addr command injection
The following function can take up to two addresses, performs no sanitization and then 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_DNS_Addr(CNetSetObj *this, char *dns1, char *dns2)
{
int result; // r0
char v5[80]; // [sp+0h] [bp-50h] BYREF
if ( !dns1 )
result = 0;
if ( dns1 )
{
sprintf(v5, "/bin/echo nameserver %s > /etc/resolv.conf", dns1); // attacker controlled dns1 field
system(v5);
if ( dns2 )
{
sprintf(v5, "/bin/echo nameserver %s >> /etc/resolv.conf", dns2);
system(v5);
}
return 1;
}
return result;
