Amazon Linux 2 : log4j (ALAS-2022-1750)

critical Nessus Plugin ID 158210

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of log4j installed on the remote host is prior to 1.2.17-18. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1750 advisory.

A flaw was found in the Java logging library Apache Log4j in version 1.x. JMSSink in Log4j 1.x is vulnerable to deserialization of untrusted data. This allows a remote attacker to execute code on the server if JMSSink is deployed and has been configured to perform JNDI requests. (CVE-2022-23302)

A flaw was found in the Java logging library Apache Log4j in version 1.x. JDBCAppender in Log4j 1.x is vulnerable to SQL injection in untrusted data. This allows a remote attacker to run SQL statements in the database if the deployed application is configured to use JDBCAppender with certain interpolation tokens.
(CVE-2022-23305)

A flaw was found in the log4j 1.x chainsaw component, where the contents of certain log entries are deserialized and possibly permit code execution. This flaw allows an attacker to send a malicious request with serialized data to the server to be deserialized when the chainsaw component is run. (CVE-2022-23307)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update log4j' to update your system.
