Summary

On December 9, 2021, a new critical 0-day vulnerability impacting multiple versions of the popular Apache Log4j 2 logging library was publicly disclosed that, if exploited, could result in Remote Code Execution (RCE) by logging a certain string on affected installations.

This specific vulnerability has been assigned CVE-2021-44228 and is also being commonly referred to as "Log4Shell" in various blogs and reports.

This CVE-2021-44228 is a Java Naming and Directory InterfaceTM (JNDI) injection vulnerability in the affected versions of Log4j listed above. It can be triggered when a system using an affected version of Log4j 2 includes untrusted data in the logged message. If this data includes a crafted malicious payload, a JNDI lookup is made to a malicious server. Depending on the information sent back (response), a malicious Java object may be loaded, which could eventually lead to RCE. Additionally, attackers who can control log messages or their parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled.

AFFECTED SOFTWARE

Apache Struts
Apache Solr
Apache Druid
Apache Flink
ElasticSearch
Flume
Apache Dubbo
Logstash
