CVE-2021-34539Network attack vector

High-privilege code execution via unvalidated Java path

Published Jun 10, 2021 · Updated Aug 4, 2024

CubeCoders AMP before 2.1.1.8 allows remote authenticated users with high privileges to execute code by changing the Java Version setting. AMP fails to validate that setting against approved Java installations, so an attacker can supply an unintended executable path that AMP launches instead of Java. Exploitation requires access to the configuration interface and high-privilege rights; the resulting process runs with AMP's available permissions.
