How the Mentioned CVE Works:
CVE-2025-1690 is a critical vulnerability in the ThemeMakers Stripe Checkout plugin for WordPress, affecting versions up to and including 1.0.1. The flaw arises due to insufficient input sanitization and output escaping on user-supplied attributes within the ‘stripe’ shortcode. Authenticated attackers with contributor-level permissions or higher can exploit this vulnerability to inject arbitrary web scripts into pages. These malicious scripts are then stored in the database and executed whenever a user accesses the compromised page. This stored cross-site scripting (XSS) attack can lead to unauthorized actions, data theft, or session hijacking, depending on the nature of the injected script.
DailyCVE Form:
Platform: WordPress
Version: 1.0.1 and earlier
Vulnerability: Stored XSS
Severity: Critical
Date: 02/27/2025
What Undercode Say:
Exploitation:
1. Exploit Code Example:
[bash]
This payload injects a malicious script into the ‘description’ attribute of the ‘stripe’ shortcode.
2. Steps to Exploit:
- Gain contributor-level access to the WordPress site.
- Inject the malicious shortcode into a post or page.
- Save the post/page, storing the XSS payload in the database.
- When a user visits the compromised page, the script executes.
Protection:
1. Update the Plugin:
- Upgrade to the latest version of the ThemeMakers Stripe Checkout plugin if a patch is available.
2. Input Sanitization:
- Implement proper input sanitization and output escaping in the plugin code.
function sanitize_input($input) { return htmlspecialchars($input, ENT_QUOTES, 'UTF-8'); }
3. WordPress Hardening:
- Restrict user roles and permissions to minimize the risk of exploitation.
- Use security plugins like Wordfence to detect and block XSS attempts.
4. Content Security Policy (CSP):
- Implement a CSP header to mitigate the impact of XSS vulnerabilities.
Header set Content-Security-Policy "default-src 'self'; script-src 'self';"
5. Database Monitoring:
- Regularly scan the database for suspicious entries or scripts.
Commands:
- Check Plugin Version:
wp plugin get thememakers-stripe-checkout --field=version
- Remove Malicious Shortcodes:
UPDATE wp_posts SET post_content = REPLACE(post_content, '[stripe', '[safe_stripe') WHERE post_content LIKE '%[stripe%';
Analytics:
- Attack Surface: High, as the plugin is widely used for e-commerce.
- Impact: Critical, due to the potential for data theft and session hijacking.
- Mitigation Difficulty: Medium, requiring plugin updates and code changes.
By following these steps, administrators can protect their WordPress sites from CVE-2025-1690 and similar vulnerabilities.
