CVE-2021-44228

Upstream information

CVE-2021-44228 at MITRE

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.

Note from the SUSE Security Team

SUSE Linux Enterprise products largely ship log4j 1.2.x which is not affected by this vulnerability. Only log4j 2.x is affected.

SUSE Rancher is not affected by this vulnerability. The Helm chart for Istio 1.5, provided by Rancher and which is currently deprecated, includes Zipkin and is vulnerable to Log4j. Customers are advised to upgrade to the recent Istio version provided in Cluster Explorer, which does not uses Zipkin and is not affect to the vulnerability.
