A deserialization flaw was found in Apache log4j 1.2.x. While reading serialized log events, they are improperly deserialized.

Note this is the same as CVE-2020-9493 which identified a deserialization issue in Apache Chainsaw. Prior to Chainsaw V2.0, Chainsaw was a component of Apache Log4j 1.2.x.

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.

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.

A flaw was found in the Apache Log4j logging library 2.x. when the logging configuration uses a non-default Pattern Layout with a Context Lookup. Attackers with control over Thread Context Map (MDC) input data can craft malicious input data that contains a recursive lookup and can cause Denial of Service.

A flaw was found in the Java logging library Apache Log4j in version 1.x . This allows a remote attacker to execute code on the server if the deployed application is configured to use JMSAppender.

In 1.x you will find that there are two places where lookups are done - that is JMSAppender.java:207 and JMSAppender.java:222 - if you set TopicBindingName or TopicConnectionFactoryBindingName to something that JNDI can handle - for example "ldap://host:port/a" JNDI will do exactly the same thing it does for 2.x - so 1.x is vulnerable, just attack vector is "safer" as it depends on configuration rather than user input

This flaw in Log4j 2.x is tracked via CVE-2021-44228

Remedy

These are the possible mitigations for this flaw for releases version 1.x: - Comment out or remove JMSAppender in the Log4j configuration if it is used - Remove the JMSAppender class from the classpath. For example: ``` zip -q -d log4j-*.jar org/apache/log4j/net/JMSAppender.class ``` - Restrict access for the OS user on the platform running the application to prevent modifying the Log4j configuration by the attacker.
