Description
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();
}
}

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for de.tum.in.ase:artemis-java-test-sandbox, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update de.tum.in.ase:artemis-java-test-sandbox to 1.11.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-23681 is resolved across your whole dependency graph.
Workarounds
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
