📄 Description (English)

The ITERAS plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple shortcodes (iteras-ordering, iteras-signup, iteras-paywall-login, iteras-selfservice) in all versions up to and including 1.8.2. This is due to insufficient input sanitization and output escaping in the combine_attributes() function. The function directly concatenates shortcode attribute values into JavaScript code within <script> tags using double-quoted string interpolation (line 489: '"'.$key.'": "'.$value.'"') without any escaping. An attacker can break out of the JavaScript string context by including a double-quote character in a shortcode attribute value and inject arbitrary JavaScript. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

🤖 AI Executive Summary

The ITERAS WordPress plugin (versions ≤1.8.2) contains a Stored Cross-Site Scripting (XSS) vulnerability in multiple shortcodes due to insufficient input sanitization in the combine_attributes() function. Authenticated attackers with Contributor-level access can inject arbitrary JavaScript that executes for all users viewing affected pages. This vulnerability poses a significant risk to WordPress-based websites in Saudi Arabia, particularly those using ITERAS for e-commerce or membership functionality.

🇸🇦 Saudi Arabia Impact Assessment
Saudi organizations using ITERAS plugin are at risk, particularly: (1) E-commerce platforms and online retailers relying on ITERAS for payment processing and customer management; (2) Media and publishing companies using ITERAS paywalls for content monetization; (3) SaaS providers and digital service platforms offering membership/subscription features; (4) Government and semi-government entities with WordPress-based citizen portals. The vulnerability allows account takeover, credential theft, malware distribution, and defacement. Organizations in the financial services sector (SAMA-regulated) face heightened compliance implications if customer data is compromised through this vector.

⚖️ Saudi Risk Score (AI)

/ 10.0
🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Audit all WordPress installations using ITERAS plugin version ≤1.8.2 across your organization
2. Review user access logs for Contributor-level and above accounts for suspicious activity in the past 30 days
3. Inspect all pages/posts using iteras-ordering, iteras-signup, iteras-paywall-login, and iteras-selfservice shortcodes for injected JavaScript
4. Disable the ITERAS plugin immediately if not actively required

PATCHING GUIDANCE:
1. Contact ITERAS plugin developers for security patch availability
2. If no patch is available, consider migrating to alternative WordPress plugins with better security practices
3. Monitor official ITERAS plugin repository and security advisories for patch releases

COMPENSATING CONTROLS (if patch unavailable):
1. Restrict Contributor-level access to only trusted users; audit and remove unnecessary accounts
2. Implement Web Application Firewall (WAF) rules to detect and block JavaScript injection attempts in shortcode attributes
3. Enable WordPress security plugins (e.g., Wordfence, Sucuri) with XSS detection capabilities
4. Implement Content Security Policy (CSP) headers to restrict inline script execution
5. Use WordPress user role management to limit who can create/edit posts with ITERAS shortcodes

DETECTION RULES:
1. Monitor WordPress database for shortcode attributes containing double-quotes or JavaScript keywords (script, onclick, onerror, etc.)
2. Log and alert on any modifications to posts/pages containing ITERAS shortcodes by Contributor+ users
3. Implement browser-based XSS detection to identify injected scripts in page source
4. Review WordPress audit logs for suspicious post/page edits during off-hours
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تدقيق جميع تثبيتات WordPress التي تستخدم مكون ITERAS الإصدار ≤1.8.2 عبر مؤسستك
2. مراجعة سجلات الوصول للمستخدمين على مستوى المساهم وما فوقه للنشاط المريب في آخر 30 يوماً
3. فحص جميع الصفحات/المنشورات التي تستخدم اختصارات iteras-ordering و iteras-signup و iteras-paywall-login و iteras-selfservice للبحث عن JavaScript المحقون
4. تعطيل مكون ITERAS فوراً إذا لم يكن مطلوباً بنشاط

إرشادات التصحيح:
1. اتصل بمطوري مكون ITERAS للحصول على توفر تصحيح أمني
2. إذا لم يكن هناك تصحيح متاح، فكر في الهجرة إلى مكونات WordPress بديلة بممارسات أمان أفضل
3. راقب مستودع مكون ITERAS الرسمي والتنبيهات الأمنية لإصدارات التصحيح

الضوابط التعويضية (إذا لم يكن التصحيح متاحاً):
1. قيد الوصول على مستوى المساهم فقط للمستخدمين الموثوقين؛ تدقيق وإزالة الحسابات غير الضرورية
2. تنفيذ قواعد جدار حماية تطبيقات الويب (WAF) للكشف عن محاولات حقن JavaScript وحجبها في سمات الاختصار
3. تفعيل مكونات أمان WordPress (مثل Wordfence و Sucuri) مع قدرات الكشف عن XSS
4. تنفيذ رؤوس Content Security Policy (CSP) لتقييد تنفيذ البرامج النصية المضمنة
5. استخدام إدارة أدوار مستخدمي WordPress لتحديد من يمكنه إنشاء/تحرير المنشورات باستخدام اختصارات ITERAS

قواعد الكشف:
1. مراقبة قاعدة بيانات WordPress للبحث عن سمات الاختصار التي تحتوي على علامات اقتباس مزدوجة أو كلمات رئيسية JavaScript (script و onclick و onerror وما إلى ذلك)
2. تسجيل والتنبيه على أي تعديلات على المنشورات/الصفحات التي تحتوي على اختصارات ITERAS من قبل مستخدمي Contributor+
3. تنفيذ الكشف عن XSS القائم على المتصفح لتحديد البرامج النصية المحقونة في مصدر الصفحة
4. مراجعة سجلات تدقيق WordPress للبحث عن تعديلات مريبة على المنشورات/الصفحات خارج ساعات العمل
