Enhance WSTG-BUSL-09 - Upload of Malicious Files

[DotDotSlashRepo]

What's the issue?
This is an enhancement request. Test Upload of Malicious Files can be enhanced through following suggestions.

• 1. Filter Evasion : Add magic byte based evasion to bypass weak content validation
• 2. Filter Evasion: Add metadata based malicious payloads, which can be triggered if uploaded file is included by the web server.
• 3. Malicious File Contents - Other File Formats : Add attacks on SVG(XXE), HTML(XSS), GIF(XSS)
• 4. Malicious File Contents - Zip : Add attack on Zip Slip
• 5. Malicious File Contents : Add a new sub section on upload of configuration file such as .htaccess, web.config etc
• 6. Tools - Add burpsuite extension - Upload Scanner - https://portswigger.net/bappstore/b2244cbb6953442cb3c82fa0a0d908fa

How do we solve it?
Content needs to be updated to accommodate these enhancements.

Hello!
I will be reviewing this week and discussing the above suggested points. Thanks for going into a detailed discussion about this matter.
There is now conflicting interest in some cases with INPV-11.1 - Local File Inclusion. We'll try to get down on this the soonest, as the team is still coming back from the holidays.

@kingthorin @jespunya @RiieCco your input would be valuable on this matter, as your free time allows.
