CVE-2019-17571 (https://nvd.nist.gov/vuln/detail/CVE-2019-17571): 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. Patch: https://src.fedoraproject.org/rpms/log4j12/c/d4c817c458d69dcc629a7271999d178b0dcb7c74?branch=master Note from Debian [0]: "CVE-2019-17571 correspond to CVE-2017-5645 for apache-log4j2. 1.2.x branch is end-of-life upstream and does not recieve a fix for this issue. Users should upgrade to Log4j 2.x." [0] https://security-tracker.debian.org/tracker/CVE-2019-17571
CVE-2020-9488 (https://nvd.nist.gov/vuln/detail/CVE-2020-9488): 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.
CVE-2022-23302: 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-2022-23305: 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-2020-9493 (http://www.openwall.com/lists/oss-security/2022/01/18/5): A deserialization flaw was found in Apache Chainsaw versions prior to 2.1.0 which could lead to malicious code execution.
