Root command execution via uploaded native library
Published Dec 19, 2024 · Updated Dec 22, 2024
Code injection in HMS Networks Ewon Flexy 205 through 14.8s0 (#2633) allows remote authenticated users to execute system commands. The workflow accepts JAR and native-library uploads over FTP, and rcgi.bin/jvmCmd starts the supplied Java class; native loading bypasses the Java sandbox. Administrative access is required, and successful exploitation escapes the chroot to obtain root access and fully control the gateway.
