Technical details
Multiple OS command injection vulnerabilities exist within the `libNetSetObj.so` library of the GeoVision GV-I/O Box 4E firmware version 2.09. The root cause is a failure to sanitize user-supplied input in functions such as `CNetSetObj::m_F_n_Set_DNS_Addr`, `m_F_n_Set_IP_Addr`, `m_F_n_Set_Net_Mask`, and `m_F_n_Set_Gate_way` before passing them to the `system()` function. These functions are reachable via the network-exposed `DVRSearch` service and the `Network.cgi` web endpoint. An attacker with high privileges can exploit these flaws by sending specially crafted network packets to execute arbitrary system commands with root privileges. A patch was released by the vendor on 2026-04-28 (likely version 2.12).
