Description
Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects.
Available Exploits
Apache Log4j2 - Remote Code Injection
Apache Log4j2 Thread Context Lookup Pattern is vulnerable to remote code execution in certain non-default configurations.
Apache Log4j2 Remote Code Injection
Apache Log4j2 <=2.14.1 JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled.
Apache Log4j2 - Remote Code Injection

Apache OFBiz - JNDI Remote Code Execution (Apache Log4j)
Apache OFBiz is affected by a remote code execution vulnerability in the bundled Apache Log4j logging library. Apache Log4j is vulnerable due to insufficient protections on message lookup substitutions when dealing with user controlled input. A remote, unauthenticated attacker can exploit this, via a web request, to execute arbitrary code with the permission level of the running Java process.
Apache Solr 7+ - Remote Code Execution (Apache Log4j)
Apache Log4j2 <=2.14.1 JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. This vulnerability affects Solr 7+.
