Payload Ideas

Security Filters in Place:

  • Blacklist filtering for common LFI patterns
  • Null byte removal
  • Single URL decoding
  • Multiple dot reduction
  • File extension restrictions
  • PHP wrapper blocking
  • Path traversal checks
  • Attempt limiting with temporary blocks

Potential Bypass Techniques:

Double URL encoding
%252e%252e%252f for ../
Mixed case wrappers
PHP:// or PhP://
Path normalization tricks
././etc/passwd or ..././..././etc/passwd
