high Nessus Plugin ID 156172

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2021:4112-1 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.

Solution

Update the affected log4j12, log4j12-javadoc and / or log4j12-manual packages.
