🔗 NVD Official
📄 Description (English)

Fortinet Multiple Products Authentication Bypass Using an Alternate Path or Channel Vulnerability — Fortinet FortiAnalyzer, FortiManager, FortiOS, and FortiProxy contain an authentication bypass using an alternate path or channel that could allow an attacker with a FortiCloud account and a registered device to log into other devices registered to other accounts, if FortiCloud SSO authentication is enabled on those devices.

🤖 AI Executive Summary

Fortinet products (FortiAnalyzer, FortiManager, FortiOS, FortiProxy) contain a critical authentication bypass vulnerability in FortiCloud SSO that allows attackers with valid FortiCloud accounts to access devices registered to other accounts. This vulnerability affects organizations using FortiCloud single sign-on authentication across their Fortinet infrastructure.

📄 Description (Arabic)

تسمح هذه الثغرة لمهاجم يمتلك حساب FortiCloud صحيح وجهاز مسجل بتجاوز آليات المصادقة والوصول إلى أجهزة Fortinet الأخرى المسجلة تحت حسابات مختلفة. يتطلب الاستغلال تفعيل مصادقة FortiCloud SSO على الأجهزة المستهدفة. يؤثر هذا على سرية البيانات والتحكم في الوصول عبر البنية التحتية الأمنية للمنظمة.

🤖 ملخص تنفيذي (AI)

منتجات Fortinet (FortiAnalyzer و FortiManager و FortiOS و FortiProxy) تحتوي على ثغرة حرجة في المصادقة تسمح لمهاجمين بحسابات FortiCloud صحيحة بالوصول إلى أجهزة مسجلة لحسابات أخرى. تؤثر هذه الثغرة على المنظمات التي تستخدم مصادقة FortiCloud الموحدة عبر بنيتها التحتية.

🔧 Remediation Steps (English)
Update all affected Fortinet products to patched versions immediately.
