Artemis Java Test Sandbox: Trust Boundary Violation
CVE-2024-23682 is a high-severity trust boundary violation 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 1.8.0 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 0.35% 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 1.8.0 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.

Official description
Artemis Java Test Sandbox versions before 1.8.0 are vulnerable to a sandbox escape when an attacker includes class files in a package that Ares trusts. An attacker can abuse this issue to execute arbitrary Java when a victim executes the supposedly sandboxed code.
