CVE-2024-23683 high CVSS 8.2

Vulnerability in de.tum.in.ase:artemis-java-test-sandbox (CVE-2024-23683)

Summary

Vulnerability in de.tum.in.ase:artemis-java-test-sandbox (CVE-2024-23683). Successful exploitation can lead to full system takeover. Exploitable via InvocationTargetException. Mitigation: upgrade to 1.7.6 or later.

Original description

The description as published by the source.

Impact

This allows an attacker to create special subclasses of InvocationTargetException that escape the exception sanitization because JUnit extracts the cause in a trusted context before the exception reaches Ares. This means that arbitrary student code can be executed in a trusted context, and that in turn allows disabling Ares and having full control over the system.

Patches

Update to version 1.7.6 or later.

Workarounds

Forbid student classes in trusted packages like, e.g., described in https://github.com/ls1intum/Ares/issues/15#issuecomment-996449371

Detailed description

Using generics, it is possible to throw checked exceptions without a throws clause:

ThrowWithoutThrowsHelper

public class ThrowWithoutThrowsHelper
{
    private final X throwable;

    private ThrowWithoutThrowsHelper(X throwable)
    {
        this.throwable = throwable;
    }

    private  R throwWithThrows() throws X
    {
        throw throwable;
    }

    public static  R throwWithoutThrows(Throwable throwable)
    {
        ThrowWithoutThrowsHelper<?> helper = new ThrowWithoutThrowsHelper(throwable);
        @SuppressWarnings("unchecked")
        ThrowWithoutThrowsHel…
