Graylog (Log4j) - Remote Code Execution CVE-2021-44228

CVSSv3 Score
Vulnerability description

Graylog is susceptible to remote code execution via the Apache Log4j 2 library prior to 2.15.0 by recording its own log information, specifically with specially crafted values sent as user input. 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.

Risk description

The risk exists that a remote unauthenticated attacker can fully compromise the server to steal confidential information, install ransomware, or pivot to the internal network.


We recommend you to upgrade the affected software to the latest version, which mitigates this vulnerability.
