"The remote SUSE Linux SUSE15 host has packages installed that are affected by a vulnerability as referenced in the
openSUSE-SU-2021:1631-1 advisory.

  - 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. (CVE-2021-4104)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
