Similarly, the ZKTeco F18 device was found to have a vulnerable upgrade mechanism that allowed arbitrary code execution via a USB key—a flaw that could let an attacker modify settings or bypass access controls entirely. More recently, a critical authentication bypass in certain CCTV camera solutions earned a CVSS score of 9.1 out of 10, underscoring the severity of leaving systems unpatched. zkteco update firmware verified
