Echo: multiple log4j packages: security update to 1.2.17-11

high Tenable Cloud Security Plugin ID 465226

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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)

Solution

Update the log4j library and its related packages to version 1.2.17-11 or later.
