CVEID:CVE-2021-45046
**DESCRIPTION:**Apache Log4j could result in remote code execution, caused by an incomplete fix of CVE-2021-44228 in certain non-default configurations. When the logging configuration uses a non-default Pattern Layout with a Context Lookup, an attacker with control over Thread Context Map (MDC) input data can craft malicious input data using a JNDI Lookup pattern to leak sensitive information and remote code execution in some environments and local code execution in all environments.
