CVE-2023-6378 is a high-severity vulnerability affecting the log back receiver component in log back version 1.4.11 and earlier versions. This vulnerability allows attackers to launch Denial-of-Service attacks by sending poisoned data. It impacts a range of systems using log back, including those running on Java EE and Jakarta EE. To protect against this vulnerability, it's essential to update the log back to a version with the necessary fixes.

How do I know if I'm affected?

To determine if you're affected by this vulnerability, check if you're using logback with the logback-receiver component enabled and reachable by an attacker. The affected versions include log back 1.2.0 to 1.2.13, 1.3.0 to 1.3.12, and 1.4.0 to 1.4.12.

What should I do if I'm affected?

If you're affected by this vulnerability have to upgrade to log back versions 1.3.14 or 1.4.14 for more complete fixes. Run the fixes under Java 9 or later. Then ensure the logback-receiver component is not enabled or reachable by potential attackers if you can't upgrade immediately.
