GLSA-202402-16 : Apache Log4j: Multiple Vulnerabilities

critical Nessus Plugin ID 190670

Language:

Description

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.

Solution

Gentoo has discontinued support for log4j. We recommend that users unmerge it:

 # emerge --ask --depclean dev-java/log4j
