Οι ευπάθειες που διορθώνουν οι νέες ενημερώσεις ασφαλείας, επηρεάζουν πολλά προϊόντα της εταιρείας, όπως τα: Azure Open Management Infrastructure, Azure Sphere, Office Excel, PowerPoint, Word και Access, kernel, Visual Studio, Microsoft Windows DNS και BitLocker.
Το Patch Tuesday Σεπτεμβρίου 2021 διορθώνει και ένα RCE σφάλμα στο MSHTML, το οποίο ανακοίνωσε η Microsoft πριν μερικές ημέρες. Η εταιρεία είχε πει ότι η συγκεκριμένη ευπάθεια είχε χρησιμοποιηθεί σε επιθέσεις εναντίον Windows συστημάτων. Πρόκειται για ένα zero-day σφάλμα, γνωστό ως CVE-2021-40444, που διορθώνεται με τη νέα ενημέρωση ασφαλείας. Η Microsoft προτείνει στους χρήστες να εφαρμόσουν άμεσα το Patch Tuesday στα συστήματά τους για να προστατευτούν από τη συγκεκριμένη ευπάθεια.

Άλλες σημαντικές ευπάθειες που διορθώνονται με το Microsoft Patch Tuesday Σεπτεμβρίου είναι οι ακόλουθες:
CVE-2021-38647: Με βαθμολογία 9,8 στην κλίμακα CVSS, είναι το πιο σοβαρό σφάλμα που διορθώνει το patch. Αυτή η ευπάθεια επηρεάζει το πρόγραμμα Open Management Infrastructure (OMI) και επιτρέπει στους επιτιθέμενους να εκτελούν απομακρυσμένες επιθέσεις.
CVE-2021-36968: Πρόκειται για μια Windows DNS privilege escalation zero-day ευπάθεια με βαθμολογία CVSS 7,8. Η Microsoft δεν έχει βρει μέχρι στιγμής κανένα στοιχείο που να αποδεικνύει ότι η ευπάθεια έχει χρησιμοποιηθεί σε επιθέσεις.
CVE-2021-26435: Είναι μια κρίσιμη ευπάθεια (CVSS 8.1) στο Microsoft Windows scripting engine. Πρόκειται για ένα memory corruption σφάλμα, το οποίο ωστόσο απαιτεί αλληλεπίδραση από το χρήστη για να χρησιμοποιηθεί.
CVE-2021-36967: Άλλη μια σοβαρή ευπάθεια με βαθμολογία 8,0 στην κλίμακα CVSS. Εντοπίζεται στην υπηρεσία Windows WLAN AutoConfig και δίνει στον επιτιθέμενο περισσότερα προνόμια στο σύστημα-στόχο.
Νωρίτερα μέσα στο Σεπτέμβριο, η εταιρεία διόρθωσε και μερικές ευπάθειες για το Microsoft Edge (Chromium).
