Authenticated SQL Injection in WordPress Donation Plugin (≤ 1.0): Risks, Detection, and How Managed-WP Shields Your Site

作者： 托管 WordPress 安全团队
日期： 2025-12-11

执行摘要

A critical vulnerability has been identified in the WordPress Donation plugin versions 1.0 and earlier. This flaw involves an authenticated SQL injection (CVE-2025-13001) accessible only to users with administrative privileges. While the requirement for admin-level access reduces the probability of remote anonymous exploitation, the potential impact is significant if an attacker gains or abuses admin credentials. The CVSS-equivalent severity rating is 7.6, aligning with injection vulnerabilities categorized under OWASP A3.

Managed-WP prioritizes these security issues and provides this comprehensive analysis: the technical implications, affected parties, detection methods, immediate mitigations, development guidelines, and proactive protection capabilities embedded in our managed Web Application Firewall (WAF) service. This is aimed at WordPress site owners, administrators, and developers needing pragmatic, security-first insights to safeguard their environments.

Overview and Risk Summary

• 受影响的软件： WordPress Donation plugin, versions ≤ 1.0.
• 漏洞类型： Authenticated SQL Injection accessible via admin roles.
• CVE 参考编号： CVE-2025-13001.
• 严重程度： Technically high (injection), with actual risk dependent on compromised admin accounts.
• 补丁状态： No official patch available at disclosure time; apply virtual patching and hardening urgently.
• Managed-WP Position: Immediate mitigation is essential using virtual patching with WAF rules and strengthening admin access controls until vendor fixes are deployed.

为什么这很重要： SQL injection gives attackers the power to manipulate your database directly—potentially exposing sensitive data or gaining full site control—especially if admin credentials fall into the wrong hands.

---

Technical Background — Understanding the SQL Injection

SQL injection occurs when unsanitized input is inserted into SQL queries, allowing attackers to alter query logic. In this vulnerability:

• Only authenticated administrators can reach the vulnerable code paths (e.g., plugin settings API or admin AJAX endpoints).
• Unsanitized input from these admin interfaces is concatenated directly into SQL commands without parameterization.
• If attackers compromise an admin account or act maliciously as an admin, they can execute crafted input to modify database behavior.

Unlike remote anonymous exploits, this vulnerability leverages elevated privileges, but the risk remains critical due to frequent credential compromises and insider threats.

---

剥削的潜在影响

Successful exploitation allows attackers to:

• Extract sensitive WordPress data, including users, emails, hashed passwords, and plugin configurations.
• Alter database entries—creating unauthorized admin accounts or changing site options.
• Plant persistent malicious content like backdoors or stored cross-site scripting (XSS) via database modifications.
• Escalate to external systems using stolen credentials stored in the database.
• Cause denial of service via malicious query overhead or corruption.
• Compromise the entire WordPress installation.

Given that admin credentials are common targets of phishing, credential reuse, or attackers with physical access, the vulnerability substantially increases security risk.

---

哪些人应该关注？

• Sites using the Donation plugin at version 1.0 or lower.
• Environments with multiple admins or shared admin credentials without strong authentication.
• Installations where wp-admin and admin-ajax.php endpoints lack additional access restrictions.
• Sites without managed firewall protections, strong monitoring, and secure backup policies.

If you manage multiple WordPress instances, a single compromise could ripple across networks—prompt action is critical.

---

How to Detect if You Are Affected or Compromised

1. Audit Plugins and Versions:
   • Check your installed plugins via WP Admin > Plugins, confirming Donation plugin version ≤ 1.0.
   • Use Managed-WP dashboards or other tools for auditing across multiple sites.
2. Monitor Administrator Activity:
   • Review audit logs for unusual admin logins or changes to admin accounts and plugin/theme files.
   • Check access logs for suspicious POST requests on wp-admin or admin-ajax.php, especially from unrecognized IPs.
3. Database Forensics:
   • Inspect slow-query or general query logs (if available) for suspicious query patterns (e.g., UNION statements or references to information_schema).
   • Check for unexpected entries or modified timestamps in key tables like wp_options and wp_users.
4. 恶意软件扫描：
   • Run thorough malware scans with Managed-WP or trusted scanners to identify injected PHP shells or suspicious scripts.
5. Signs of Compromise to Watch:
   • New or altered admin users with generic emails.
   • Unexpected changes to site URLs.
   • Unusual scheduled tasks (cron jobs) calling remote resources.
   • Unexplained outbound network activity on hosting servers.

Any confirmation of these indicators mandates immediate incident response.

立即采取的缓解措施

If using Donation plugin ≤ 1.0, follow this prioritized action plan immediately:

1. Isolate and Deactivate
   – Temporarily disable the Donation plugin via WP Admin if possible.
   – If admin access is compromised, rename the plugin folder via SFTP or hosting panel to disable it.
2. Secure Admin Access
   – Enforce strong, unique passwords for all admin accounts.
   – Mandate two-factor authentication (2FA) for admin users.
   – Restrict wp-admin and admin-ajax.php access by IP whitelisting or VPN where feasible.
3. 轮换凭证和密钥
   – Rotate database credentials and any sensitive API keys stored in the site.
4. Restore from Clean Backup
   – If compromise is suspected, restore site from backup predating the incident.
   – Secure the environment (updated passwords, active WAF) prior to reactivation.
5. Conduct Scans and Enable Monitoring
   – Perform full malware and integrity scans.
   – Activate and review logs for suspicious activity.
6. 评估插件的必要性
   – Consider removing the Donation plugin until an official patch is available or switch to alternative donation solutions.
7. Prevent Re-Infection
   – Audit for rogue scheduled tasks, unauthorized plugins, or suspicious files.

These measures drastically lower exposure and buy time to implement a sustainable fix.

开发商补救指南

Developers managing the Donation plugin must remediate this SQL injection vulnerability thoroughly by properly sanitizing and validating inputs. Key techniques include:

• 利用 $wpdb->准备 to safely parameterize dynamic SQL queries.
• 使用 $wpdb->insert, $wpdb->update， 和 $wpdb->delete for safer data operations.
• Validating and sanitizing all input (e.g., intval(), sanitize_text_field（）, wp_verify_nonce()).
• Avoiding direct concatenation of user data into SQL queries.
• Escaping output appropriately when rendering data.

不安全示例（请勿使用）：

// Vulnerable: concatenates user input directly into SQL
$id = $_POST['donation_id'];
$sql = "SELECT * FROM {$wpdb->prefix}donations WHERE id = $id";
$results = $wpdb->get_results($sql);

Secure alternatives:

1) Using $wpdb->准备:

$id = intval($_POST['donation_id']);
$sql = $wpdb->prepare(
    "SELECT * FROM {$wpdb->prefix}donations WHERE id = %d",
    $id
);
$results = $wpdb->get_results($sql);

2) Inserting data with proper sanitization:

$insert = $wpdb->insert(
    "{$wpdb->prefix}donations",
    [
        'amount' => floatval($_POST['amount']),
        'payer_email' => sanitize_email($_POST['email'])
    ],
    ['%f', '%s']
);

3) Always verify capabilities and nonces for admin actions:

• 查看 current_user_can('manage_options').
• 使用 wp_verify_nonce() in AJAX requests.

Unit testing and static analysis should be part of the development lifecycle to catch potential SQL vulnerabilities early.
