[GitHub] [incubator-doris] caiconghui opened a new issue #7511: [Bug] Apache Log4j2 does not always protect from infinite recursion in lookup evaluation.
caiconghui opened a new issue #7511:
URL: https://github.com/apache/incubator-doris/issues/7511
### Search before asking
- [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues.
### Version
master
### What's Wrong?
Apache Log4j2 versions 2.0-alpha1 through 2.16.0 did not protect from uncontrolled recursion from self-referential lookups. When the logging configuration uses a non-default Pattern Layout with a Context Lookup (for example, $${ctx:loginId}), attackers with control over Thread Context Map (MDC) input data can craft malicious input data that contains a recursive lookup, resulting in a StackOverflowError that will terminate the process. This is also known as a DOS (Denial of Service) attack.
### What You Expected?
Upgrade to Log4j 2.3.1 (for Java 6), 2.12.3 (for Java 7), or 2.17.0 (for Java 8 and later).
### How to Reproduce?
_No response_
### Anything Else?
