CVE-2022-27903Network attack vector

Root command execution via imported UNL parameters

Published May 4, 2022 · Updated Aug 3, 2024

OS command injection in EVE-NG Professional through 4.0.1-65 and Community through 2.0.3-112 allows remote authenticated users to run root commands. The configuration parser passes attacker-edited virtualization command parameters from imported UNL files into operating-system commands without neutralizing shell metacharacters. An authenticated EVE-NG account and permission to import and edit a UNL lab file are required; successful exploitation grants root-level command execution on the server.
