/blog (Status: 301) [Size: 185] [--> <http://10.0.0.205/blog/>]
/blog gets me to the login page of a blog.
The version name and author’s name led to me the source code and exploit of the app.
There is a file upload vulnerability.
Github:
I checked the default files. config.ini contains the default password. I could try the default password.
But, we can download the file from the server. This confirmed that it used the default password.
Let’s upload a random image which we will edit in the burpsuite.
