Summary
OS command injection reported (CVE-2026-12486). Successful exploitation can lead to full system takeover. Exploitable via libNetSetObj.so.
Original description
The description as published by the source.
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;
}

CVE-2026-12486 — CWE-78 / CVSS v3 9.1
Attack vector: remote (network-reachable) / no user interaction
Attack surface: libNetSetObj.so / system / DVRSearch / Network.cgi
Plan: 1) Audit SBOM/dependencies, 2) Stage→prod upgrade, 3) Add WAF/proxy monitoring on affected endpoints, 4) Hunt IOCs in logs.
Refs: see the GHSA / vendor advisory / patched release linked on this page.
OS command injection (CWE-78) has been reported. Attackers reach the vulnerable code path via libNetSetObj.so.
Check the vendor advisory for the affected versions. Attack surface: libNetSetObj.so / system / DVRSearch / Network.cgi.
Severity: Critical (CVSS 9.1/10). Successful exploitation can lead to full system takeover.
Update to the patched release per vendor advisory.
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Audit SBOM/dependencies to find affected services.
