Ruby to Python migration: Convert post-2020 exploit modules and tools

[Copilot]

Description

Continues Ruby to Python migration effort. Converts 3 post-2020 exploit modules and 1 exploit development tool to Python, following the established python_framework architecture.

Converted Modules:

• apache_hugegraph_gremlin_rce.py - CVE-2024-27348 Gremlin sandbox bypass
• chamilo_bigupload_webshell.py - CVE-2023-4220 unrestricted file upload
• example_webapp.py - Educational web exploitation example

Converted Tools:

• find_badchars.py - Bad character detection for exploit development (supports raw, WinDbg, GDB, hex formats)

All modules:

• Inherit from RemoteExploit + HttpExploitMixin
• Implement CheckCode for vulnerability detection
• Support standalone execution via argparse
• Include comprehensive docstrings and usage examples

Example usage:

# Standalone execution
python3 modules/exploits/linux/http/apache_hugegraph_gremlin_rce.py \
    --host target.com --port 8080 --check-only

# Bad character detection
python3 tools/exploit/find_badchars.py -b "\\x00\\xff" \
    -i windbg_output.txt -t windbg

Verification

• Start msfconsole
• Load converted modules: use exploit/linux/http/apache_hugegraph_gremlin_rce
• Verify options and targets are properly configured
• Run standalone: python3 modules/exploits/linux/http/apache_hugegraph_gremlin_rce.py --help
• Verify find_badchars.py processes test input correctly
• Verify all modules follow python_framework patterns
• Verify CheckCode implementation returns expected values
• Document updated in PYTHON_TRANSLATIONS.md (entries 55-58)
