jSQL Injection Java Based Application For Automatic SQL Database Injection

jSQL Injection
jSQL Injection

jSQL Injection, an Open Source Java Based Automatic SQL database Injection Software.

It is free an open source and cross-platform for Windows, Linux, Mac OS X. Also a lightweight application used to find database information from a distant server with speed.

jSQL Injection is also part of the official penetration testing distribution Kali Linux and is included in other distributions like Pentest Box, Parrot Security OS, ArchStrike or BlackArch Linux.

This software is developed using open source libraries like Spring, Spock and Hibernate, and it uses platform Travis CI for continuous integration.

Each program update is tested in the cloud on Travis CI using Java version 8 through 13, and against various MySQL, PostgreSQL and H2 databases. Source code is open to pull request and to any contribution about multi-threading, devops, optimization, unit and integration tests.


  • Automatic injection of 34 kinds of databases: Access, Altibase, C-treeACE, CockroachDB, CUBRID, DB2, Derby, Exasol, Firebird, FrontBase, H2, Hana, HSQLDB, Informix, Ingres, InterSystems-IRIS, MaxDB, Mckoi, MemSQL, MimerSQL, MonetDB, MySQL, Neo4j, Netezza, NuoDB, Oracle, PostgreSQL, Presto, SQLite, SQL Server, Sybase, Teradata and Vertica
  • Multiple injection strategies: Normal, Error, Stacked, Blind and Time
  • Various injection processes: Default, Zip, Dios
  • Sandbox for SQL and tampering scripting
  • List to inject multiple targets
  • Read and write file using injection
  • Create and display Web shell and SQL shell
  • Bruteforce password hash
  • Search for admin pages
  • Hash, encode and decode text
  • Authenticate using Basic, Digest, NTLM and Kerberos
  • Proxy connection on HTTP, SOCKS4 and SOCKS5

Install Java 8 up to Java 15, then download the latest release and double-click on the file jsql-injection-v0.82.jar to launch the software. You can also type java -jar jsql-injection-v0.82.jar in your terminal to start the program.

If you are using Kali Linux then get the latest release using command sudo apt-get -f install jsql, or make a system full upgrade with apt update then apt full-upgrade.

[Test-bed scripts]

Use the sample scripts to test injection on your local environment. First install a development environment like EasyPHP, then download the test-bed PHP scripts and place them into www/.


$link = mysqli_connect('localhost', 'root', '', 'my_database');

$result = $link->query("SELECT col1, col2 FROM my_table where id=$_GET[id]");

while ($row = $result->fetch_array($result, MYSQLI_NUM))
echo join(',', $row);


Full Path Disclosure, Injection strategies: routed query, WAF detection
