Class Loading Vulnerability in Artemis
Impact
This affects all Artemis users who test Java assignments. Ares is not required.
Students code that gets automatically tested can run arbitrary code in the container,
or arbitrary code on the machine of an assessor in case of manual correction.
Patches
The problem cannot be resolved easily in Ares itself. Use the Maven Enforcer Plugin as follows:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-enforcer-plugin</artifactId>
<version>3.0.0</version>
<executions>
<execution>
<id>enforce-no-student-code-in-trusted-packages</id>
<phase>process-classes</phase>
<goals>
<goal>enforce</goal>
</goals>
</execution>
</executions>
<configuration>
<rules>
<requireFilesDontExist>
<files>
<!-- ADD HERE THE RULES ARES TELLS YOU ARE MISSING -->
</files>
</requireFilesDontExist>
</rules>
</configuration>
</plugin>
This fails the build if student classes reside in such packages that Ares trusts. Trusted packages added in Ares using @AddTrustedPackage
should be added as well.
