انتشار آپدیت امنیتی ماه آپریل 2026 و رفع 167 آسیب پذیری

تیتر مطالب

آپدیت امنیتی ماه آپریل مایکروسافت در مجموع 167 آسیب‌پذیری را برطرف می‌کند.
به‌ گزارش مرکز مدیریت راهبردی افتا، از بین این آسیب‌پذیری‌ها 2 مورد آن‌ها Zero-day و 8 مورد Critical هستند.

آمار آسیب‌پذیری‌ها به تفکیک نوع، به شرح زیر است:

  • 93 مورد افزایش سطح دسترسی (Privilege Escalation)
  • 13 مورد دور زدن مکانیزم های امنیتی
  • 20 مورد اجرای کد از راه دور (RCE)
  • 21 مورد افشای اطلاعات
  • 10 مورد منع سرویس (DoS)
  • 9 مورد جعل هویت (Spoofing)

 

دو آسیب پذیری Zero-day

CVE-2026-32201- آسیب‌پذیری Spoofing در Microsoft SharePoint Server: مایکروسافت این نقص را که در حملات واقعی مورد سوءاستفاده قرار گرفته بود، رفع کرده است. مشکل ناشی از اعتبارسنجی نادرست ورودی‌ها در SharePoint است که به مهاجم اجازه می‌دهد عملیات Spoofing روی شبکه انجام دهد.

طبق گزارش مایکروسافت، سوءاستفاده موفق از این نقص می‌تواند باعث مشاهده اطلاعات حساس (Confidentiality) و تغییر داده‌های افشا شده (Integrity) شود. اما دسترسی به منابع (Availability) به‌طور کامل محدود نمی‌شود. 

CVE-2026-33825- آسیب‌پذیری Elevation of Privilege در Microsoft Defender: این نقص به مهاجم اجازه می‌دهد تا دسترسی SYSTEM را به دست آورد. مشکل در Microsoft Defender Antimalware Platform نسخه ۴.۱۸.۲۶۰۳۰.۳۰۱۱ برطرف شده است و به‌روزرسانی به‌صورت خودکار دریافت می‌شود.

کاربران می‌توانند به صورت دستی نیز از مسیر Windows Security > Virus & threat protection > Protection Updates > Check for updates آن را نصب کنند.

لازم به ذکر است چندین آسیب‌پذیری RCE در Microsoft Office نیز اصلاح شده‌اند که می‌توانند از طریق پنجره Preview یا باز کردن اسناد مخرب مورد سوءاستفاده قرار بگیرند.

پیشنهاد می شود با توجه به تعداد زیاد آسیب‌پذیری‌ها و وجود Zero-dayهای فعال، به‌روزرسانی فوری سیستم‌ها و پایش دقیق رویدادهای امنیتی در صورت امکان آپدیت ها در اسرع وقت انجام شود.
