CVE-2021-44832

Apache Log4j2 vulnerable to RCE via JDBC Appender when attacker controls configuration

Published Dec 28, 2021 CVSS 3.1 · 6.6 Medium EPSS 97.9% KEV · Not listed
Description
Apache Log4j2 versions 2.0-beta7 through 2.17.0 (excluding security fix releases 2.3.2 and 2.12.4) are vulnerable to a remote code execution (RCE) attack when a configuration uses a JDBC Appender with a JNDI LDAP data source URI when an attacker has control of the target LDAP server. This issue is fixed by limiting JNDI data source names to the java protocol in Log4j2 versions 2.17.1, 2.12.4, and 2.3.2.
