Vulnerabilities associated with org.apache.logging.log4j:log4j-core:2.9.1
BDSA-2021-3731 (CRITICAL): Apache Log4j, as used in many popular services, is vulnerable to improperly allowing lightweight directory access protocol (LDAP) access via Java naming and directory interface (JNDI). A remote attacker able to supply the end application with specially crafted input that is then processed by the Log4j subcomponent could cause the execution of arbitrary Java code.
Note
log4j-api packages by themselves do not contain the vulnerable functionality and are therefore unaffected. log4j-core packages and the upstream overarching source repository are affected.
A previously suggested mitigation of setting environment variable
LOG4J_FORMAT_MSG_NO_LOOKUPS=trueis not recommended. This mitigation has been proven inadequate against this vulnerability.This vulnerability is partially fixed in 2.15.0-rc2 by this commit and this commit. These fixes were deemed incomplete. See BDSA-2021-3779 (CVE-2021-45046) for more details.
This vulnerability is listed as exploitable by the Cybersecurity & Infrastructure Security Agency in their Known Exploited Vulnerabilities Catalog.
