关于Bypass-Url-Parser

Bypass-Url-Parser是一款功能强大的URL绕过工具，该工具可以使用多种方法实现URL绕过并访问目标站点的40X受保护页面。

工具下载

由于该工具基于Python 3 开发，因此我们首先需要在本地设备上安装并配置好Python 3环境。接下来，使用下列命令将该项目源码克隆至本地：

git clone https://github.com/laluka/bypass-url-parser.git

Linux配置

# Deps

sudo apt install -y bat curl virtualenv python3

# Tool

virtualenv -p python3 .py3

source .py3/bin/activate

pip install -r requirements.txt

./bypass_url_parser.py -u http://thinkloveshare.com/juicy_403_endpoint/

Docker配置

docker build -t thelaluka/bypass-url-parser:latest .

docker run --rm -it --net=host -v "$PWD:/host" thelaluka/bypass-url-parser:latest -u http://127.0.0.1:8000/dummy

docker run --rm -it --net=host -v "$PWD:/host" thelaluka/bypass-url-parser:latest -u /host/urls.lst

# TODO later, tag & push releases to dockerhub :)

# -t thelaluka/bypass-url-parser:0.2.0

# docker push thelaluka/bypass-url-parser:latest

工具使用

Bypass Url Parser, made with love by @TheLaluka

A tool that tests MANY url bypasses to reach a 40X protected page.

 

Usage:

    ./bypass_url_parser.py -u <URL> [-m <mode>] [-o <outdir>] [-S <level>] [(-H <header>)...] [-r <num>]

                           [-s <ip>] [--spoofip-replace] [-p <port>] [--spoofport-replace] [--dump-payloads]

                           [-t <threads>] [-T <timeout>] [-x <proxy_url>] [-v | -d | -dd]

 

Program options:

    -H, --header <header>     设置要使用的Header，格式为"Cookie: can_i_haz=fire"

    -m, --mode <mode>      设置绕过模式[默认: all]

    -o, --outdir <outdir>       结果的输出目录

    -x, --proxy <proxy_url>    设置代理，格式为http://proxy_ip:port.

    -S, --save-level <level>    存储结果等级，从0（禁用）到3（完整）[默认: 1]

    -s, --spoofip <ip>         注入到ip-specific头中的IP地址

    -p, --spoofport <port>     注入到port-specific头中的端口号

    -r, --retry <num>          失败后的重试次数 [默认: 3]

    -t, --threads <threads>     设置扫描并行线程[默认: 1]

    -T, --timeout <timeout>    Request times out after N seconds [默认: 5]

    -u, --url <URL>           待绕过的目标URL

 

General options:

    -h, --help                显示工具帮助信息

    -v, --verbose             Verbose模式输出

    -d, --debug              显示调试信息

    -dd, --debug             开启二级调试模式，显示所有的类输出

    -V, --version             显示工具版本信息

 

Misc options:

    --spoofip-replace         在'http_headers_ip'绕过模式下禁用显示内部IP列表

    --spoofport-replace       在'http_headers_port'模式下禁用显示内部端口列表    

--dump-payloads         打印该工具生成的所有Payload

 

样例:

    ./bypass_url_parser.py -u "http://127.0.0.1/juicy_403_endpoint/" -s 8.8.8.8 -d

    ./bypass_url_parser.py -u /path/urls -t 30 -T 5 -H "Cookie: me_iz=admin" -H "User-agent: test"

期望的输出结果

./bypass_url_parser.py -u http://127.0.0.1:8000/foo/bar

工具使用样例

参数解析

Bypass-Url-Parser支持以多种方式定义某些参数：

./bypass_url_parser.py -u http://thinkloveshare.com/test

./bypass_url_parser.py -u /path/urls

cat /path/urls | ./bypass_url_parser.py -u -

echo 'http://thinkloveshare.com/test' | ./bypass_url_parser.py -u -

绕过模式

当前版本的Bypass-Url-Parser支持下列绕过模式：

all, mid_paths, end_paths, case_substitution, char_encode, http_methods, http_versions, http_headers_scheme, http_headers_ip, http_headers_port

Spoofip / Spoofport

./bypass_url_parser.py -u /path/urls -s /path/custom_ip --spoofip-replace

./bypass_url_parser.py -u /path/urls -p "3000, 9443, 10443"

结果保存

默认配置下，如果目标为单个URL，工具会将运行结果存储到/tmp/tmpXXX-bypass-url-parser/triaged-
bypass.log日志文件中。使用样例如下：

./bypass_url_parser.py -S 0

./bypass_url_parser.py -o /tmp/bypass-res

./bypass_url_parser.py -o /tmp/bypass-res2 -S 2 -u http://thinkloveshare.com/juicy_403_endpoint/
