Installation

run the command below:

git clone https://github.com/Nova-Noir/SimExp_Cracker.git
cd SimExp_Cracker
python -m pip install -r requirements.txt

Usage

After Cloning, you should first edit pwn.py, change the value of URL at the Line 15 to your own SimExp_URL

Note: no '/' needed at the end of the URL

Encrypt

SimExp Cracker can encrypt your own *.xml file into the API-recognizableContent using Experiment.encrypt.

It takes a byte-like value as its argument

with open('path_to_the_xml_file.xml', 'rb') as f:
    c = f.read()
    content = Experiment.encrypt(c)
    print(content)

Decrypt

SimExp Cracker can decrypt the Content using Experiment.decrypt

In order to get the Content, you need first capture the packet posted to /ServiceAPI/UpdateRecord

To do so, while the Packet Capture Software is running, you could click submit button (recommended) or click close button and then find the data in your Packet Capture Software.

You can also getUserID、 LabID、RecordID、FileName and LabName in this packet, which would be useful when you upload.

encrypted_content = 'encrypted_content_here'
with open('path_to_decrypted_xml.xml', 'w') as f:
    f.write(Experiment.decrypt(encrypted_content))

Upload

SimExp Cracker can upload the file to the server using Experiment.upload

r = Experiment('UserID', LabID, 'LabName', RecordID, 'FileName')
c = Experiment.encrypt(content)
r.upload(c)

Content

SimExp Cracker can get your experiments content using Experiment.gen_content

with open('Content.html', 'w') as f:
        cookie = {
            "ASP.NET_SessionId": "%YOUR_COOKIE_HERE%"
        }
        # Method 1
        f.write(Experiment.get_content(r"Upload\\LabDate\\%LABNAME%\\%FILE_NAME%.xml",
                                       # make sure the url string has tag r, otherwise you gotta use "\\\\" instead.
                                       cookie))

        # Method 2
        r = Experiment('UserID', LabID, 'LabName', RecordID, 'FileName')
        f.write(r.gen_content(cookie))

How it works?

I'll write a full blog on my own blog.

A simple reverse. Removed some noise and then got the source. Write the exploit then. Too easy to write a blog, so just a quick talk here.
