AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

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.

SQL Injection
AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

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.

Input Validation
AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H

Apache Log4j <=2.14.1 JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled (CVE-2021-44228).

Remedy

As per upstream: - In prior releases confirm that if the JDBC Appender is being used it is not configured to use any protocol other than Java. - Note that only the log4j-core JAR file is impacted by this vulnerability. Applications using only the log4j-api JAR file without the log4j-core JAR file are not impacted by this vulnerability.
