T-Reqs-HTTP-Fuzzer - A Grammar-Based HTTP Fuzzer
T-Reqs (Two Requests) is a grammar-based HTTP Fuzzer (https://www.kitploit.com/search/label/Fuzzer) written as a part of the paper (https://bahruz.me/papers/ccs2021treqs.pdf) titled "T-Reqs: HTTP Request Smuggling with Differential Fuzzing" which was presented at ACM CCS 2021 (https://www.sigsac.org/ccs/CCS2021/accepted-papers.html).
BibTeX of the paper: @inproceedings{ccs2021treqs,
title={T-Reqs: HTTP Request Smuggling with Differential Fuzzing},
author={Jabiyev, Bahruz and Sprecher, Steven and Onarlioglu, Kaan and Kirda, Engin},
booktitle={Proceedings of the 2021 ACM SIGSAC Conference on Computer and Communications Security},
pages={1805--1820},
year={2021}
}
About T-Reqs is for fuzzing (https://www.kitploit.com/search/label/Fuzzing) HTTP servers by sending mutated HTTP requests with versions 1.1 and earlier. It has three main components: 1) generating inputs, 2) mutating generated inputs (https://www.kitploit.com/search/label/Inputs) and 3) delivering them to the target server(s). Generating Inputs A CFG grammar fed into the fuzzer is used to generate HTTP requests. As the example grammar shown below is tailored for request line fuzzing, every request line component and possible values for each of them are explicitly specified. This allows us to generate valid requests with various forms of request line and also to treat each request line component as a separate unit from the mutation perspective. ': [''], '': [''], '': [''], '': ['GET', 'HEAD', 'POST', 'PUT', 'DELETE', 'CONNECT', 'OPTIONS', 'TRACE', 'PATCH'], '': [' '], '': ['/_URI_'], '': ['HTTP'], '': ['/'], '': ['0.9', '1.0', '1.1'], '': ['\r\n'], '': ['Host: _HOST_\r\nConnection:close\r\nX-Request-ID: _REQUEST_ID_\r\n'], '': ['Content-Length: 5\r\n\r\nBBBBBBBBBB'],"> '':

Mutating Inputs Each component can be marked in two ways: string mutable and tree mutable (see (https://github.com/bahruzjabiyev/T-Reqs-HTTP-Fuzzer/blob/main/config) the example configuration). If a component is string mutable, then a random character can be deleted, replaced, or inserted at a random position. In the example shown below (left side), the last character in the protocol version (1) is deleted, the third letter in the method name (S) is replaced with R, and a forward slash is inserted at the beginning of the URI. Whereas, if a component is tree mutable, then a random component can be deleted, replaced, or inserted at a random position under that component. The example below (right side) shows three tree mutations applied on the request line component: 1) method is replaced by protocol, 2) an extra URI is inserted after the current URI, and 3) the existing proto< /em> is deleted.

Usage Configuration The fuzzer should be informed about the user preferences about the generation and mutation of inputs. More specifically, the input grammar, the mutable components, mutation preferences among other things should be specified in the configuration file (see an example configuration (https://github.com/bahruzjabiyev/T-Reqs-HTTP-Fuzzer/blob/main/config)). Running modes To be able to reproduce the inputs generated and mutated in each iteration, a seed number is used. In fact, this seed number serves as a seed for random number generations during the formation and mutation of an input. Depending on how these seeds are fed into the fuzzer, it runs in one of these two modes: individual and collective. In the individual mode, inputs are generated and mutated based on the seeds specified by a user. In the command below, a single seed (i.e., 505) is specified. Alternatively, a list of seeds could be specified with -f option (see help page for more). python3 main.py -i -c config -s 505
Whereas, in the collective mode (which is default), it starts from zero as the seed value and increments it in each iteration until the end number is reached. The beginning and end numbers can be customized. python3 main.py -c config
Using for Finding HRS discrepancies HTTP Request Smuggling relies on different body parsing (https://www.kitploit.com/search/label/Parsing) behaviors between servers where one server uses Transfer-Encoding header while the other prefers Content-Length header to decide the boundaries of a request body, or one server ignores a request body, whereas the other one processes it. To analyze the body parsing of servers in response to various mutations in various forms of an HTTP request, we need to have a feedback mechanism installed on those servers to tell us about the body parsing behavior. One way of installing a feedback mechanism on a server, is to run the server in the reverse-proxy mode and have it forward requests to a "feedback provider" script running as a service. This service measures the length of the body in received requests and saves it for comparing it later with other servers. An example "feedback provider (https://github.com/bahruzjabiyev/T-Reqs-HTTP-Fuzzer/blob/main/code/feedback-server.py)" script is available in this repository. However, this script sends the body length information back in a response assuming that this information is stored on the client (https://www.kitploit.com/search/label/Client) side.

Just wondering how others go about doing this - the most unobtrusive way without paywall or donation popups seemed to be ads, but the Google terms explicitly reference content about hacking being a disqualifier for being approved (and I've been rejected twice citing this). Other ad networks always seem so untrustworthy and spam-y, I refuse to do the paywall idea - information should be able to be shared without that kind of stuff. What kind of successful monetization have people been able to do that doesn't greatly inconvenience the user? submitted by /u/jsownz (https://www.reddit.com/user/jsownz)
