A project for fuzzing HTTP/1.1 CL.0 Request Smuggling Attack Vectors.
About
Thank you to @albinowax, @defparam and @d3d else this tool would not exist. Inspired by the tool Smuggler all attack gadgets adapted from Smuggler and https://portswigger.net/research/how-to-turn-security-research-into-profit

Usage
usage: clzero.py [-h] [-url URL] [-file FILE] [-index INDEX] [-verbose] [-no-color] [-resume] [-skipread] [-quiet] [-lb] [-config CONFIG] [-method METHOD]CLZero by Moopingeroptional arguments: -h, --help show this help message and exit -url URL (-u), Single target URL. -file FILE (-f), Files containing multiple targets. -index INDEX (-i), Index start point when using a file list. Default is first line. -verbose (-v), Enable verbose output. -no-color Disable colors in HTTP Status -resume Resume scan from last index place. -skipread Skip the read response on smuggle requests, recommended. This will save a lot of time between requests. Ideal for targets with standard HTTP traffic. -quiet (-q), Disable output. Only successful payloads will be written to ./payloads/ -lb Last byte sync method for least request latency. Due to th e nature of the request, it cannot guarantee that the smuggle request will be processed first. Ideal for targets with a high amount of traffic, and you do not mind sending multiple requests. -config CONFIG (-c) Config file to load, see ./configs/ to create custom payloads -method METHOD (-m) Method to use when sending the smuggle request. Default: POST
single target attack:
-
python3 clzero.py -u https://www.target.com/ -c configs/default.py -skipread
-
python3 clzero.py -u https://www.target.com/ -c configs/default.py -lb
Multi target attack:
-
python3 clzero.py -l urls.txt -c configs/default.py -skipread
-
python3 clzero.py -l urls.txt -c configs/default.py -lb
