CVE-2026-12486

*** Pendiente de traducción *** 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.<br /> <br /> <br /> `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.)<br /> <br /> <br /> #### CNetSetObj::m_F_n_Set_IP_Addr command injection<br /> <br /> 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. <br /> <br /> <br /> <br /> int __fastcall CNetSetObj::m_F_n_Set_IP_Addr(const char **this, char *ip_addr)<br /> <br /> {<br /> <br /> bool v2; // zf<br /> <br /> char v4[72]; // [sp+0h] [bp-48h] BYREF<br /> <br /> <br /> <br /> v2 = *this == 0;<br /> <br /> if ( *this )<br /> <br /> v2 = ip_addr == 0;<br /> <br /> if ( v2 )<br /> <br /> return 0;<br /> <br /> sprintf(v4, "/sbin/ifconfig %s %s", *this, ip_addr); // attacker controlled ip address <br /> <br /> system(v4);<br /> <br /> return 1;<br /> <br /> }
