What is ending?

ending is a flexible SQL injection framework and CLI that works just as well for simple injections as it does for very complex ones.

Like sqlmap, it can be used out of the box for common SQL injection scenarios. However, ending is designed so that when the target stops being simple, you don’t need to abandon the tool and write custom scripts — you write python code instead.

Documentation and tutorials are available here.

Installation

$ pip install cfreal-ending

A different approach to SQL injection

Most tools work fine for straightforward SQL injections over HTTP. However, when dealing with a complex case, a WAF, or other limitations, you often end up writing a custom script to inject your payloads. This is why ending was built.

Python-based target definitions

In ending, targets are defined using Python design files.

Instead of only configuring a URL and parameters through CLI arguments, you write a small Python method that sends an SQL payload to the target.

This function can be as simple as a single HTTP request — or as complex as needed.

Because it’s Python, you can naturally handle:

• authentication and sessions
• custom headers and encodings
• non-HTTP protocols
• WAF bypass logic
• complex request flows

For simple targets, this is often only a few lines of code. For complex targets, it removes the need to switch tools entirely.

AST-based SQL generation

ending operates on the SQL Abstract Syntax Tree (AST) level, rather than building payloads as raw strings.

• Injection techniques (UNION, error-based, blind, time-based, etc.) are implemented in a generic and reusable way
• Each DBMS translates the AST into its own SQL dialect

Most of the time, you don't need to get that deep into the tool, as ending does everything itself. But if you face a complex injection, you can change the way AST nodes are converted into SQL syntax, and thus build advanced bypasses, such as:

• To get rid of badchars (for instance, a<b can be written as a BETWEEN 0 AND b)
• To make function calls less easy to spot for the WAF: SUBSTR(a, b) becomes SUBSTR# comment\n(a,b)

And it only takes a few lines of code!

First steps

It takes three steps: import, configure, and query.

Import an HTTP request

Configure a design

Supported databases

Currently, 5 databases are supported:

• MySQL
• PostgreSQL
• SQLite
• Oracle
• Microsoft SQL Server (MSSQL)
