```I prefer Jekyll for building my blog. Please try to read /home/web/flags/flag1.txt.[http://34.82.101.212:8001] (down)[http://59.124.168.42:8001]``````After scanning the website i found that we can use the exploit of "File path traversal" from two links:
1st link: [http://34.82.101.212:8001/feed.xml]
2nd link: [http://34.82.101.212:8001/hope/2019/12/19/welcome-to-jekyll.html]
And then you just inject the path  ../../../../../../../../../../../../../../../../etc/passwd and you will get the content of file.And now we just changet [/etc/passwd] with [/home/web/flags/flag1.txt]Bingooo you get the flag. ```
