Security Advisory for Log4j 2 CVE-2021-44228 vulnerability

Issued: December 10^th, 2021
Updated: March 23rd, 2022

Broadcom Software has investigated multiple Apache Log4j 2 vulnerabilities that were recently reported to Apache.  CVE identifiers CVE-2021-44228, CVE-2021-45046, CVE-2021-45105, and CVE-2021-4104 have been assigned to these vulnerabilities.  These vulnerabilities have a cumulative Critical risk rating, and exploit code is in the wild.  The Log4j team has addressed these vulnerabilities in Log4j 2.16.0.

Log4j Versions Affected: All versions from 2.0-beta9 to 2.16.0

Note that CVE-2021-4104 affects only Log4j 1.2, and does not impact the Log4j 2.x branch.

CVE-2021-44228 Description: Apache Log4j2 2.0-beta9 through 2.12.1 and 2.13.0 through 2.15.0 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. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0, this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects.

CVE-2021-45046 Description: It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-default configurations. This could allow attackers with control over Thread Context Map (MDC) input data when the logging configuration uses a non-default Pattern Layout with either a Context Lookup or a Thread Context Map pattern to craft malicious input data using a JNDI Lookup pattern resulting in an information leak and remote code execution in some environments and local code execution in all environments. Log4j 2.16.0 (Java 8) and 2.12.2 (Java 7) fix this issue by removing support for message lookup patterns and disabling JNDI functionality by default.

CVE-2021-45105 Description: Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3) did not protect from uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed in Log4j 2.17.0 and 2.12.3.

CVE-2021-4104 Description: JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, 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.
