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.<\/p>\n
`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.)<\/p>\n
#### CNetSetObj::m_F_n_Set_Net_Mask command injection<\/p>\n
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. <\/p>\n
int __fastcall CNetSetObj::m_F_n_Set_Net_Mask(const char **this, char *netmask_addr)<\/p>\n
{<\/p>\n
bool v2; \/\/ zf<\/p>\n
char v4[72]; \/\/ [sp+0h] [bp-48h] BYREF<\/p>\n
v2 = *this == 0;<\/p>\n
if ( *this )<\/p>\n
v2 = netmask_addr == 0;<\/p>\n
if ( v2 )<\/p>\n
return 0;<\/p>\n
sprintf(v4, “\/sbin\/ifconfig %s netmask %s”, *this, netmask_addr); \/\/ attacker controlled netmask_addr<\/p>\n
system(v4);<\/p>\n
return 1;<\/p>\n
}<\/p>\n
Severity: 9.1 | CRITICAL<\/p>\n
