Artemis Java Test Sandbox: Improper Isolation or Compartmentalization
CVE-2024-23683 is a high-severity improper isolation or compartmentalization vulnerability in Artemis Java Test Sandbox from Ls1intum, with a CVSS 3.1 base score of 8.2 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. The record lists version 1.7.6 as the first without the flaw, so updating Artemis Java Test Sandbox to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.36% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Artemis Java Test Sandbox to 1.7.6 or a later version.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

The underlying weakness: Improper Isolation or Compartmentalization
The product does not properly compartmentalize or isolate functionality, processes, or resources that require different privilege levels, rights, or permissions.
How developers prevent this class of flaw
- Break up privileges between different modules, objects, or entities. Minimize the interfaces between modules and require strong access control between them.
