(CVE-2021-45046) Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number. Log4j 2.16.0 fixes this issue by removing support for message lookup patterns and disabling JNDI functionality by default. Log4j 2.15.0 makes a best- effort attempt to restrict JNDI LDAP lookups to localhost by default. This could allows 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 (for example, $$) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input data using a JNDI Lookup pattern resulting in a denial of service (DOS) attack. (CVE-2021-44228) - It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non- default configurations. ![]() Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects. From version 2.16.0, this functionality has been completely removed. From log4j 2.15.0, this behavior has been disabled by default. 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. 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. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2021-1553 advisory. The version of java-1.8.0-openjdk installed on the remote host is prior to 1.8.0.312.b07-0.66.
