CVE-2025-34186: Ilevia eve x1 server firmware os command injection vulnerability

IIlevia · Eve X1 Server Firmware

Ilevia EVE X1/X5 Server version ≤ 4.7.18.0.eden contains a vulnerability in its authentication mechanism. Unsanitized input is passed to a system() call for authentication, allowing attackers to inject special characters and manipulate command parsing. Because the binary interprets non-zero exit codes from system() as successful authentication, remote attackers can bypass authentication and gain full access to the system.
