Installation

from Binary

The installation is easy. You can download a prebuilt binary from releases page, unpack and run! or with

from Source

If you have go1.13+ compiler installed and configured:

In order to update the tool, you can use -u flag with go get command.

from GitHub

Usage

Basic Usage

Simply, CRLFuzz can be run with:

Flags

This will display help for the tool. Here are all the switches it supports.

| Flag | Description |
|------------------ |------------------------------------------------ |
| -u, --url | Define single URL to fuzz |
| -l, --list | Fuzz URLs within file |
| -X, --method | Specify request method to use _(default: GET)_ |
| -o, --output | File to sa |
| -d, --data | Define request data |
| -H, --header | Pass custom header to target |
| -x, --proxy | Use specified proxy to fuzz |
| -c, --concurrent | Set the concurrency level _(default: 25)_ |
| -s, --silent | Silent mode |
| - | mode |
| - | Show current CRLFuzz |
| -h, --help | Display its help |

Target

You can define a target in 3 ways:

#### Single URL

#### URLs from list

#### from Stdin

In case you want to chained with other tools.

Method

By default, CRLFuzz makes requests with GET method.
If you want to change it, you can use the -X flag.

Output

You can also sa results to a file with -o flag.

Data

If you want to send a data request using POST, DELETE. PATCH or other methods, you just need to use -d flag.

Adding Headers

May you want to use custom headers to add cookies or other header parts.

Using Proxy

Using a proxy, proxy string can be specified with a protocol:// prefix to specify alternati protocols.

Concurrency

Concurrency is the number of fuzzing at the same time. Default value CRLFuzz provide is 25, you can change it by using -c flag.

Silent

If you activate this silent mode with the -s flag, you will only see targets.

Unlike silent mode, it will display error details if there is an error with the -v flag.

To display the current of CRLFuzz with the -V flag.

Library

You can use CRLFuzz as a library.
