شرکت مایکروسافت در روز سه‌شنبه ۹ ماه آگوست (۱۸ مرداد)، اصلاحیه‌های امنیتی ماهانه خود را منتشر کرد. در این اصلاحیه ۲ آسیب‌پذیری روز صفر و در مجموع ۱۲۱ نقص امنیتی وصله شد.
جزئیات آسیب پذیر‌ی‌های ماه آگوست
از ۱۲۱ آسیب‌پذیری وصله شده، ۱۷ مورد با درجه اهمیت «حیاتی» و از نوع اجرای کد از راه دور و یا افزایش سطح دسترسی هستند. تعداد هر یک از این آسیب‌پذیری‌ها به تفکیک بر اساس فهرست زیر می‌باشد:
- ۶۴ نمونه آسیب‌پذیری افزایش سطح دسترسی
- ۶ نمونه آسیب‌پذیری عبور از راهکارهای امنیتی
- ۳۱ نمونه آسیب‌پذیری اجرای کد از راه دور
- ۱۲ نمونه آسیب‌پذیری افشای اطلاعات

آسیبپذیریهای روز صفر
اصلاحیه‌ی امنیتی این ماه ۲ آسیب‌پذیری روز صفر را برطرف می‌کند که یکی از آنها به طور فعال در حملات مورد سوء استفاده قرار گرفته است:
۱- آسیب پذیری روز صفر DogWalk
آسیب‌پذیری روز صفر مورد بهره برداری با عنوان “DogWalk” و با CVE-2022-34713 شناسایی می‌شود. این آسیب پذیری ناشی از نقص path traversal در ابزار تشخیصی پشتیبانی ویندوز (MSDT) است و مهاجمان می‌توانند از آن برای اجرای کد از راه دور در سیستم‌های آسیب پذیر سوء استفاده کنند.
هکرها این کار را با افزودن فایل‌های اجرایی مخرب به Startup ویندوز انجام می‌دهند؛ زمانی که قربانی، یک فایل diagcab. ساخته شده‌ی مخرب (دریافت شده از طریق ایمیل یا دانلود از وب) را باز می‌کند.
در نتیجه، مرتبه بعدی که شخص ویندوز خود را راه اندازی مجدد (restart) می‌کند، فایل‌های اجرایی قرار داده شده به طور خودکار اجرا می‌شوند تا عملیات مخربی همچون دانلود پیلودهای بدافزاری اضافی انجام شود.
در حالی که مهاجمان احراز هویت نشده می‌توانند از این آسیب‌پذیری در حملات با پیچیدگی کم سوء استفاده کنند اما بهره برداری موفقیت آمیز به تعامل کاربر نیاز دارد (فریب دادن هدف برای باز کردن پیوست‌های ایمیل مخرب یا کلیک کردن روی لینک برای دانلود و اجرای یک فایل مخرب).
- در سناریوی حمله ایمیلی، مهاجم با ارسال فایل ساخته‌شده مخصوص به کاربر و متقاعد کردن کاربر به باز کردن فایل، از آسیب‌پذیری سوء استفاده می‌کند.
- در سناریوی حمله مبتنی بر وب، مهاجم یک وب‌سایت را میزبانی می‌کند (یا از یک وب‌سایت آسیب‌پذیر سوءاستفاده می‌کند تا محتوای ارائه‌شده توسط کاربر را بپذیرد یا میزبانی کند) که حاوی یک فایل دستکاری شده برای سوءاستفاده از آسیب‌پذیری است.
[سیستم‌های آسیب پذیر]
به گفته مایکروسافت، CVE-2022-34713 بر «تمامی نسخه‌های ویندوز تحت پشتیبانی»، از جمله آخرین نسخه‌های کلاینت و سرور یعنی ویندوز 11 و ویندوز سرور 2022 تأثیر می‌گذارد.
۲- آسیب پذیری روز صفر Microsoft Exchange
آسیب‌پذیری روز صفر دیگر با CVE-2022-30134 شناسایی می‌شود و از نوع افشای اطلاعات در Microsoft Exchange است که به مهاجم اجازه می‌دهد پیام‌های ایمیل هدف را بخواند. مایکروسافت اعلام کرده که این آسیب‌پذیری به طور عمومی افشا شده اما در حملات شناسایی نشده است.
توصیه می‌شود که هرچه سریع‌تر وصله‌های امنیتی منتشر شده را دانلود و نصب نمایید.
