CVE-2021-44228

Status Candidate

Overview

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.

Log4Shell HTTP Scanner
Posted Sep 1, 2024
Authored by Spencer McIntyre, RageLtMan | Site metasploit.com

Versions of Apache Log4j2 impacted by CVE-2021-44228 which allow JNDI features used in configuration, log messages, and parameters, do not protect against attacker controlled LDAP and other JNDI related endpoints. This Metasploit module will scan an HTTP end point for the Log4Shell vulnerability by injecting a format message that will trigger an LDAP connection to Metasploit. This Metasploit module is a generic scanner and is only capable of identifying instances that are vulnerable via one of the pre-determined HTTP request injection points. These points include HTTP headers and the HTTP request path. Known impacted software includes Apache Struts 2, VMWare VCenter, Apache James, Apache Solr, Apache Druid, Apache JSPWiki, Apache OFBiz.

Authored by Spencer McIntyre, RageLtMan, Nicholas Anastasi | Site metasploit.com

The Ubiquiti UniFi Network Application versions 5.13.29 through 6.5.53 are affected by the Log4Shell vulnerability whereby a JNDI string can be sent to the server via the remember field of a POST request to the /api/login endpoint that will cause the server to connect to the attacker and deserialize a malicious Java object. This results in OS command execution in the context of the server application. This Metasploit module will start an LDAP server that the target will need to connect to.

Log4Shell HTTP Header Injection
Posted Jan 12, 2022
Authored by sinn3r, Michael Schierl, Spencer McIntyre, juan vazquez | Site metasploit.com

This Metasploit module will exploit an HTTP end point with the Log4Shell vulnerability by injecting a format message that will trigger an LDAP connection to Metasploit and load a payload. The Automatic target delivers a Java payload using remote class loading. This requires Metasploit to run an HTTP server in addition to the LDAP server that the target can connect to. The targeted application must have the trusted code base option enabled for this technique to work. The non-Automatic targets deliver a payload via a serialized Java object. This does not require Metasploit to run an HTTP server and instead leverages the LDAP server to deliver the serialized object. The target application in this case must be compatible with the user-specified JAVA_GADGET_CHAIN option.
