Vulnerability Title
GeoVision GV-I/O Box 4E libNetSetObj.so OS command injection vulnerability
Vulnerability 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_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;
}

Vulnerability Title
GeoVision GV-I/O Box 4E 命令注入漏洞
Vulnerability Description
GeoVision GV-I/O Box 4E是日本GeoVision公司的一款用于安全监控系统的网络输入输出扩展控制模块。 GeoVision GV-I/O Box 4E V2.09版本存在命令注入漏洞,该漏洞源于libNetSetObj.so功能中CNetSetObj::m_F_n_Set_IP_Addr函数对IP地址参数未进行清理,存在OS命令注入漏洞,可能导致特制网络数据包执行命令。
