This flaw has been filed for Log4j 1.x, and the corresponding flaw information for Log4j 2.x is available at: https://access.redhat.com/security/cve/CVE-2021-44228\n\nNote this flaw ONLY affects applications which are specifically configured to use JMSAppender, which is not the default, or when the attacker has write access to the Log4j configuration for adding JMSAppender to the attacker\u0027s JNDI LDAP endpoint. \n\nIf the Log4j configuration is set TopicBindingName or TopicConnectionFactoryBindingName configurations allowing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228 Log4j 2.x, Log4j 1.x is vulnerable. However, the attack vector is reduced as it depends on having write access, which is not a standard configuration rather than untrusted user input. These are sufficient factors beyond the attacker\u0027s control.\n\nThe tomcat package shipped with Red Hat Enterprise Linux does not include log4j but it does include a default configuration for log4j, log4j.properties, which could be used with tomcat if users choose to install and configure the library. The JMSAppender is not enabled by default, and the permissions of the file can only be modified as root.\n\nRed Hat Virtualization ships log4j12-1.2.17, but it is used and configured in a way which makes this flaw not possible to exploit.
