What is CVE-2026-12851?

Multiple OS command injection vulnerabilities exist in the internal library libNetSetObj.so of the GeoVision GV-I/O Box 4E 2.09. These vulnerabilities allow an attacker to execute arbitrary commands by sending specially crafted network packets. The unauthorized command execution can be initiated through functions like m_F_n_Set_DNS_Addr, which performs no input sanitization and directly calls the system command with user-controlled input. This issue is accessible through network-exposed services such as DVRSearch and Network.cgi, highlighting a significant risk to the device's network configuration and overall security.

Affected Version(s)
