Théophile Gervreau-Mercier a2b1ff5f41 security: fix all HIGH priority items from TODO.SECURITY.md
Items resolved:
- #3 (HIGH): Move file uploads outside webroot to STORAGE_ROOT (/var/www/posterg/storage).
  Uploads were previously stored in public/admin/actions/data/ which is web-accessible.
- #4 (HIGH): Align file paths and add media.php controller.
  DB paths are now storage-relative (theses/YEAR/ID/file, covers/file).
  New public/media.php serves files with path-traversal jail, MIME allow-list,
  and proper caching headers. memoire.php and search.php updated to use /media.php?path=.
  Also fixed: cover images were never recorded in thesis_files (broken INSERT).
- #5 (HIGH): RateLimit::getClientIdentifier() now uses REMOTE_ADDR only.
  HTTP_X_FORWARDED_FOR and HTTP_CLIENT_IP are attacker-controlled headers that
  allowed unlimited rate-limit bypass by rotating spoofed IPs.
- #6 (HIGH): Port public/admin/.htaccess security rules to nginx/posterg.conf.
  Apache .htaccess directives are silently ignored by nginx; none were active.
  CSP added to /admin/ location block, .log file denial added globally,
  autoindex off made explicit. Documented in nginx/HTACCESS_TO_NGINX.md.

Supporting changes:
- config/bootstrap.php: add STORAGE_ROOT constant
- nginx/SECURITY_HEADERS.md: updated to reflect admin CSP and pending public CSP
- docs/TODO.SECURITY.md: items #3-6 moved to resolved; priority order updated

Nginx Configuration - Post-ERG

This directory contains nginx configuration and setup scripts for the Post-ERG thesis website.

📁 Files

  • posterg.conf - Complete nginx configuration file
  • setup-password.sh - Script to create admin passwords
  • SETUP.md - Detailed setup instructions
  • QUICK_REFERENCE.md - Command reference and troubleshooting

🚀 Quick Start

1. Deploy nginx configuration (automated)

# From your local machine
just deploy-nginx

# Then on the server:
ssh posterg
sudo bash /tmp/deploy-production.sh

The deployment script will:

  • Fix file permissions (posterg group)
  • Set up admin password (if needed)
  • Install nginx configuration
  • Test and reload nginx
  • Verify PHP-FPM is running

2. SSL/TLS

SSL/TLS is handled by the upstream reverse proxy and is already working. No additional SSL setup is needed on this server.
