Arbitrary code execution in de.tum.in.ase:artemis-java-test-sandbox
Summary
Because of the missing checkLink(String) override in the SecurityManager, students can load libraries and execute arbitrary code.
Details
Using System.load(String) or System.loadLibrary(String) students can load and execute arbitrary code.
private static native void start(List<String> args);
public static void main(String[] args) {
System.load(new File("path_to_lib.so").getAbsolutePath());
start(List.of(args));
}Adding this to the security manager (and a translation) should fix the issue:
@Override
public void checkExec(String cmd) {
try {
if (enterPublicInterface())
return;
throw new SecurityException(localized("security.error_link")); //$NON-NLS-1$
} finally {
exitPublicInterface();
}
}PoC
