Unauthenticated command execution via unsanitized nginxPath
Published Apr 13, 2024 · Updated Sep 3, 2024
Command injection in cym1102 nginxWebUI 3.9.0 through 3.9.9 allows remote attackers to execute operating-system commands via nginxPath. The saveCmd handlePath function incorporates the nginxPath value into a shell command without rejecting or escaping shell metacharacters. No authentication or user interaction is required, and successful exploitation runs commands with the nginxWebUI service account's privileges.
