Vulnerability: Read More about CVE-2021-4104
Checkmarx Project: SamHeadrickCx/easybuggy4sb
Repository URL: https://github.com/SamHeadrickCx/easybuggy4sb
Branch: master
Scan ID: 94cbf8fd-fbe8-49c7-9c55-da0658f9cbfc


JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions.
