CVE-2025-32124

Executive Summary

CVE-2025-32124 is a critical Blind SQL Injection vulnerability discovered in the WordPress plugin Behance Portfolio Manager (slug: portfolio-manager-powered-by-behance), developed by Eleopard. The vulnerability resides in the improper neutralization of special elements used in an SQL command, allowing an unauthenticated attacker to perform blind SQL injection attacks. This affects all versions up to and including 1.7.5. As of this report, no official patch has been released, and no public proof-of-concept (PoC) code is available. The CVSS score of 7.6 (High) reflects the ease of exploitation (network-based, low complexity, no privileges required) and the potential for high impact on confidentiality, with limited impact on integrity and availability.

Supply Chain & Package Security

This vulnerability affects a WordPress plugin distributed through the official WordPress plugin repository. Users who have installed this plugin via the WordPress dashboard or via direct download are at risk. The supply chain risk is elevated because the plugin is unmaintained and no patch is available, meaning users must either implement a virtual patch or remove the plugin entirely.

CVSS Breakdown & Threat Level

• CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L
• Base Score: 7.6 (High)
• Attack Vector: Network (AV:N) – The vulnerability can be exploited remotely.
• Attack Complexity: Low (AC:L) – No special conditions are required.
• Privileges Required: None (PR:N) – No authentication needed.
• User Interaction: None (UI:N) – No user action required.
• Scope: Unchanged (U:S) – The vulnerable component and the impacted component are the same.
• Confidentiality Impact: High (C:H) – Successful exploitation can lead to full database disclosure.
• Integrity Impact: Low (I:L) – Limited ability to modify data.
• Availability Impact: Low (A:L) – Limited ability to disrupt service.

Threat Level: High. The combination of unauthenticated remote exploitation and the potential for data exfiltration makes this a critical risk for any site using the plugin.

Deep Dive & Mechanics

The vulnerability is a classic Blind SQL Injection in the WordPress plugin portfolio-manager-powered-by-behance. The plugin likely fails to sanitize user-supplied input before using it in SQL queries. Since it is a blind injection, the attacker does not see direct error messages or data output; instead, they infer information based on the application's response (e.g., time delays or boolean responses).

Attack Vector: The injection point is likely in a parameter passed to a shortcode, AJAX handler, or query variable. Common injection points in WordPress plugins include $_GET, $_POST, or $_REQUEST variables that are directly concatenated into SQL queries without proper escaping or prepared statements.

Exploitation Scenario:

1. An attacker identifies a vulnerable parameter (e.g., ?id=1).
2. They inject a payload like 1 AND (SELECT SLEEP(5)) to test for time-based blind injection.
3. If the response is delayed, the parameter is vulnerable.
4. The attacker then uses boolean-based or time-based techniques to extract data character by character, such as database version, usernames, and passwords.

Impact: Full compromise of the WordPress database, including user credentials, posts, and configuration data.

Vulnerable vs. Patched Code

Since no patch is available, we can only hypothesize the vulnerable code pattern. The vulnerable code likely looks like:

// VULNERABLE CODE (hypothetical)
$id = $_GET['id'];
$query = "SELECT * FROM wp_posts WHERE ID = $id";
$result = $wpdb->get_results($query);

A patched version would use prepared statements:

// PATCHED CODE (hypothetical)
$id = intval($_GET['id']);
$query = $wpdb->prepare("SELECT * FROM wp_posts WHERE ID = %d", $id);
$result = $wpdb->get_results($query);

The key difference is the use of $wpdb->prepare() which safely escapes the input.

Exploitation & Lab Setup

Red Team (Offensive)

Prerequisites:

• A WordPress instance with Behance Portfolio Manager <= 1.7.5 installed and activated.
• A tool like sqlmap or manual scripting.

Step-by-Step Exploitation:

1. Identify the vulnerable endpoint. Use a web proxy (e.g., Burp Suite) to intercept requests. Look for parameters like id, cat, page, or any custom parameter passed to the plugin's shortcode.

2. Test for time-based blind injection. Send a request with a sleep payload:

   GET /?portfolio_id=1 AND (SELECT SLEEP(5)) HTTP/1.1
   Host: target.com
   

   If the response takes 5 seconds longer, the parameter is vulnerable.

3. Automate extraction with sqlmap:

   sqlmap -u "http://target.com/?portfolio_id=1" --batch --dbs
   

   This will enumerate databases.

4. Extract data:

   sqlmap -u "http://target.com/?portfolio_id=1" -D wordpress --tables
   sqlmap -u "http://target.com/?portfolio_id=1" -D wordpress -T wp_users --dump
   

Note: No public exploit code is available, so the above is a generic approach.

Blue Team (Defensive)

Detection:

• Monitor for SQL injection patterns in web logs, especially SLEEP, BENCHMARK, OR 1=1, and time-based anomalies.
• Use a Web Application Firewall (WAF) with rules to block SQLi.

Hunting:

• Search for requests to the plugin's endpoints with unusual parameters.
• Look for database error messages in logs (though blind injection may not produce errors).

Lab Setup for Testing:

• Use a local WordPress installation with the vulnerable plugin.
• Install a debugging plugin like "Query Monitor" to see SQL queries.
• Use sqlmap in a controlled environment to test detection rules.

Indicators of Compromise (IOCs)

• Network IOCs:

  • HTTP requests containing SQL keywords in parameters: SLEEP, BENCHMARK, UNION, SELECT, OR 1=1.
  • Unusually long response times (time-based injection).
  • Repeated requests to the same endpoint with varying parameters.

• Host IOCs:

  • Unexpected database queries in logs (e.g., SELECT * FROM wp_users).
  • New user accounts created with administrative privileges.
  • Modified or deleted posts/pages.

• File IOCs:

  • Presence of webshells in the WordPress uploads directory.
  • Modified plugin files (though unlikely if only SQLi is used).

Remediation & Mitigation

Immediate Actions:

1. Disable the plugin if it is not critical to business operations.
2. Implement a virtual patch using a WAF (e.g., ModSecurity, Cloudflare) to block SQLi patterns.
3. Monitor logs for any signs of exploitation.

Long-term Fix:

• Since no official patch is available, consider forking the plugin and applying the fix yourself (using prepared statements).
• Replace the plugin with an alternative that is actively maintained.

Workaround:

• If the plugin must remain active, restrict access to its endpoints via .htaccess or server-level rules:

  <IfModule mod_rewrite.c>
      RewriteEngine On
      RewriteCond %{QUERY_STRING} (SLEEP|BENCHMARK|UNION|OR\s+1=1) [NC]
      RewriteRule .* - [F,L]
  </IfModule>
