Description
Description
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;
}
