TITLE

Apache Log4j allows insecure JNDI lookups

DESCRIPTION

Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) 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. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), 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. Apache Log4j allows insecure JNDI lookups that could allow an unauthenticated, remote attacker to execute arbitrary code with the privileges of the vulnerable Java application using Log4j.CVE-2021-4104 Affected CVE-2021-44228 Affected CVE-2021-45046 AffectedCVE-2021-4104 Affected CVE-2021-44228 Affected CVE-2021-45046 Affected. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ===================================================================== Red Hat Security Advisory Synopsis: Critical: Red Hat Data Grid 8.2.2 security update Advisory ID: RHSA-2021:5132-01 Product: Red Hat JBoss Data Grid Advisory URL: https://access.redhat.com/errata/RHSA-2021:5132 Issue date: 2021-12-14 CVE Names: CVE-2021-44228 ===================================================================== 1.
