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 andnot deleted.===========================================================================================================================###########################################################################################################################===========================================================================================================================# Exploit Title: MonoCMS Blog - Account Takeover (CSRF)# Date: September 29th, 2020# 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: CVE-2020-25986
