Description
Implemented LFI vulnerability where only double url-encoded with nested traversal works
So, to access path like "../file.py", the parameter that needs to be passed is "%252E%252E%252E%252F%252E%252Ffile.py", which translates to "..././file.py"
[More safeguards can be added to make LFI even more difficult]
Added verbose error messages to help understand what kind of path will bypass checks
Added download service report functionality where this vulnerability is injected
Limited file storage to 50 pdfs (configurable) to avoid filling the disk space
Testing
