مایکروسافت در روز گذشته به‌روزرسانی‌های امنیتی ماه آگوست ۲۰۱۹ را منتشر کرده که در آن‌ها ۹۴ آسیب‌پذیری رفع شده است. در بین نقص‌های رفع شده، ۲۶ مورد دارای درجه حساسیت بحرانی هستند.
به گزارش معاونت بررسی مرکز افتا، به نقل از پایگاه اینترنتی BleepingComputer، مهم‌ترین نقص‌های برطرف شده در این ماه، دو آسیب‌پذیری در پروتکل دسترسی از راه دور به دسکتاپ (RDP) هستند که تمامی نسخه‌های ویندوز را تحت تاثیر قرار می‌دهند و می‌توانند به هدف دانلود و نصب بدافزار در رایانه‌های مختلف مورد سوء استفاده قرار گیرند.
دو آسیب‌پذیری RDP کشف شده مشابه نقص RDP قبلی در ویندوز تحت عنوان BlueKeep، هستند. هر دو آسیب‌پذیری جدید قابلیت تبدیل به کرم رایانه‌ای را دارند و همچنین می‌توانند برای اجرای کد از راه دور مورد بهره‌برداری قرار گیرند.
مهاجم می‌تواند برای نصب بدافزار روی سیستم‌های آلوده بصورت دسترسی از راه دور و گسترش آن در شبکه قربانی از این آسیب‌پذیری‌ها سوء استفاده کند.
بدلیل اینکه این دو آسیب‌پذیری جدید تمامی نسخه‌های ویندوز و ویندوز سرور را تحت تاثیر قرار می‌دهند، نسبت به نقص BlueKeep خطرناک‌تر هستند. دو آسیب‌پذیری ذکر شده با شناسه‌های CVE-۲۰۱۹-۱۱۸۱ و CVE-۲۰۱۹-۱۱۸۲ معرفی شده‌اند.
دو آسیب‌پذیری بحرانی دیگر در سرویس دسترسی از راه دور به دسکتاپ ویندوز با شناسه‌های CVE-۲۰۱۹-۱۲۲۲ و CVE-۲۰۱۹-۱۲۲۶ رفع شده‌اند که این دو آسیب‌پذیری نیز منجر به اجرای کد از راه دور می‌شوند.
