1.Features(特性)
-
该项目是一款无须借助
dnslog且完全无害的JNDI反连检测工具，解析RMI和LDAP协议实现，可用于甲方内网自查 -
Support for lists of URLs.
-
Fuzzing for more than 60 HTTP request headers (not only 3-4 headers as previously seen tools).
-
Fuzzing for HTTP POST Data parameters.
-
Fuzzing for JSON data parameters.
-
WAF Bypass payloads.
2.Installation(安装)
$ pip3 install -r requirements.txt
3.Usage(Jndi监听和记录)
win
JNDIScan-Windows.exe -p 8888
Linux
./JNDIScan-Linux -p 8888
Mac
./JNDIScan-Darwin -p 8888
4.Usage(扫描)
需要配合jndi监听和记录工具使用，--server参数为 jndi监听的内网ip及端口
$ python3 log4j2-intranet-scan.py -h
usage: log4j2-intranet-scan.py [-h] [-u URL] [-p PROXY] [-l USEDLIST] [--request-type REQUEST_TYPE]
[--headers-file HEADERS_FILE] [--run-all-tests] [--exclude-user-agent-fuzzing]
[--wait-time WAIT_TIME] [--waf-bypass] [--test-CVE-2021-45046] [--server SERVER]
[--disable-http-redirects]
optional arguments:
-h, --help show this help message and exit
-u URL, --url URL Check a single URL. example('http://vultest.com/test.jsp')
-p PROXY, --proxy PROXY
send requests through proxy
-l USEDLIST, --list USEDLIST
Check a list of URLs.
--request-type REQUEST_TYPE
Request Type: (get, post) - [Default: get].
--headers-file HEADERS_FILE
Headers fuzzing list - [default: headers.txt].
--run-all-tests Run all available tests on each URL.
--exclude-user-agent-fuzzing
Exclude User-Agent header from fuzzing - useful to bypass weak checks on User-Agents.
--wait-time WAIT_TIME
Wait time after all URLs are processed (in seconds) - [Default: 5].
--waf-bypass Extend scans with WAF bypass payloads.
--test-CVE-2021-45046
Test using payloads for CVE-2021-45046 (detection payloads).
--server SERVER ldap_server
--disable-http-redirects
Disable HTTP redirects. Note: HTTP redirects are useful as it allows the payloads to have
higher chance of reaching vulnerable systems.
Scan a Single URL(GET)
$ python3 log4j2-intranet-scan.py --server "192.168.130.1:8888" -u https://vultest.com/login.jsp
Scan a Single URL using all Request Methods: GET, POST (url-encoded form), POST (JSON body)
$ python3 log4j2-intranet-scan.py --server "192.168.130.1:8888" -u https://vultest.com/login.jsp --run-all-tests
Discover WAF bypasses on the environment.
$ python3 log4j2-intranet-scan.py --server "192.168.130.1:8888" -u https://vultest.com/login.jsp --waf-bypass
Scan a list of URLs
$ python3 log4j2-intranet-scan.py --server "192.168.130.1:8888" -l urls.txt
5.Example(演示)
监听结果存储在当前文件夹下的
result.html文件中,查看路径参数在批量扫描中可以定位到存在漏洞的uri，需要配合扫描生成的scanfile.txt中的随机路径参数使用
Single URL
Urllist
