  script_set_attribute(attribute:"description", value:
"According to the versions of the log4j package installed, the EulerOS installation on the remote host is affected by the
following vulnerabilities :

  - 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)

  - CVE-2020-9493 identified a deserialization issue that was present in Apache Chainsaw. Prior to Chainsaw
    V2.0 Chainsaw was a component of Apache Log4j 1.2.x where the same issue exists. (CVE-2022-23307)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security
advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
issues.");
