CRITICAL 9.3

DescriptionCVE.org

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. Due to the binary's interpretation of non-zero exit codes as successful authentication, remote attackers can bypass authentication and gain full access to the system.

AnalysisAI

Ilevia EVE X1/X5 Server version ≤ 4.7.18.0.eden contains a vulnerability in its authentication mechanism. Rated critical severity (CVSS 9.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.

Technical ContextAI

This vulnerability is classified as OS Command Injection (CWE-78), which allows attackers to execute arbitrary operating system commands on the host. 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. Due to the binary's interpretation of non-zero exit codes as successful authentication, remote attackers can bypass authentication and gain full access to the system. Affected products include: Ilevia Eve X1 Server Firmware.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Avoid passing user input to shell commands. Use language-specific APIs instead of shell execution. Apply strict input validation with allowlists.
