CVE-2023-39474

Code execution via unvalidated remote JAR loading

Published May 3, 2024 · Updated Sep 18, 2024

Remote code execution in Inductive Automation Ignition before 8.1.35 allows remote attackers to run code when a client connects. The downloadLaunchClientJar function loads a remote JAR without validating that it is a legitimate Gateway binary. Exploitation requires a user to launch Designer or Vision Client against a malicious server, and the code runs with that user's privileges.
