"The remote host is affected by the vulnerability described in GLSA-202402-16 (Apache Log4j: Multiple Vulnerabilities)

  - Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data
    which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when
    listening to untrusted network traffic for log data. This affects Log4j versions up to 1.2 up to 1.2.17.
    (CVE-2019-17571)

  - Improper validation of certificate with host mismatch in Apache Log4j SMTP appender. This could allow an
    SMTPS connection to be intercepted by a man-in-the-middle attack which could leak any log messages sent
    through that appender. Fixed in Apache Log4j 2.12.3 and 2.13.1 (CVE-2020-9488)

  - A deserialization flaw was found in Apache Chainsaw versions prior to 2.1.0 which could lead to malicious
    code execution. (CVE-2020-9493)

  - JMSSink in all versions of Log4j 1.x is vulnerable to deserialization of untrusted data when the attacker
    has write access to the Log4j configuration or if the configuration references an LDAP service the
    attacker has access to. The attacker can provide a TopicConnectionFactoryBindingName configuration causing
    JMSSink to perform JNDI requests that result in remote code execution in a similar fashion to
    CVE-2021-4104. Note this issue only affects Log4j 1.x when specifically configured to use JMSSink, 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-2022-23302)

  - By design, the JDBCAppender in Log4j 1.2.x accepts an SQL statement as a configuration parameter where the
    values to be inserted are converters from PatternLayout. The message converter, %m, is likely to always be
    included. This allows attackers to manipulate the SQL by entering crafted strings into input fields or
    headers of an application that are logged allowing unintended SQL queries to be executed. Note this issue
    only affects Log4j 1.x when specifically configured to use the JDBCAppender, which is not the default.
    Beginning in version 2.0-beta8, the JDBCAppender was re-introduced with proper support for parameterized
    SQL queries and further customization over the columns written to in logs. 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-2022-23305)

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