# Exploit Title: MonoCMS Blog 1.0 - Arbitrary File Deletion (Authenticated)
# Date: 2020-09-20
# Exploit Author: Shahrukh Iqbal Mirza (@shahrukhiqbal24)
# Vendor Homepage: https://monocms.com/download
# Software Link: https://monocms.com/download
# Version: 1.0
# Tested On: Windows 10 (XAMPP)
# CVE: N/A

Proof of Concept:
1.	In the upload images page, make a request to delete an already uploaded image. If no image present, upload an image and then make a request to delete that image.
2.	Notice the Request URL
<ip>/base_path_to_cms/uploads?delimg=../../../../../Temp/Copy.txt
This deletes the file ‘copy.txt’ from C:\Temp
3.	Use simple directory traversals to delete arbitrary files.

Note: php files can be unlinked and not deleted.
