Η Microsoft κυκλοφόρησε χθες τις ενημερώσεις ασφαλείας για το μήνα Σεπτέμβριο, γνωστές και ως Patch Tuesday Σεπτεμβρίου 2020. Αυτό το μήνα, η εταιρεία διόρθωσε 129 ευπάθειες σε 15 προϊόντα της (από τα Windows έως το ASP.NET).
Αξίζει να σημειωθεί ότι στο Patch Tuesday Σεπτεμβρίου 2020, 32 από τις 129 ευπάθειες που διορθώνονται, ταξινομήθηκαν ως ζητήματα απομακρυσμένης εκτέλεσης κώδικα (RCE), τα οποία είναι σφάλματα που επιτρέπουν στους επιτιθέμενους να εκμεταλλευτούν ευάλωτες εφαρμογές από απόσταση, μέσω ενός δικτύου.
Από αυτές τις 32 ευπάθειες, οι 20 ταξινομήθηκαν ως “κρίσιμες”, δηλαδή είναι μερικά από τα πιο σημαντικά σφάλματα που επιδιορθώθηκαν στα προϊόντα της Microsoft αυτόν τον μήνα. Η λίστα των 20 κρίσιμων RCE περιλαμβάνει σφάλματα σε:
- Windows (CVE-2020-1252)
- On-premise Microsoft Dynamics 365 συστήματα (CVE-2020-16857, CVE-2020-16862)
- Windows Graphics Device Interface (GDI) (CVE-2020-1285)
- Microsoft SharePoint (CVE-2020-1200, CVE-2020-1210, CVE-2020-1452, CVE-2020-1453, CVE-2020-1576, CVE-2020-1595)
- Microsoft SharePoint Server (CVE-2020-1460)
- Windows Media Audio Decoder (CVE-2020-1593, CVE-2020-1508)
- Microsoft COM for Windows (CVE-2020-0922)
- Windows Text Service Module (CVE-2020-0908)

- Windows Camera Codec Pack (CVE-2020-0997)
- Visual Studio (CVE-2020-16874)
Όλες οι ευπάθειες που αναφέρονται παραπάνω είναι σοβαρά ζητήματα, και ειδικά αυτές που επηρεάζουν τα Windows, το SharePoint και το Dynamics 365 (καθώς αυτά τα συστήματα είναι συχνά εγκατεστημένα σε μεγάλα εταιρικά δίκτυα).
Η Microsoft κυκλοφορεί κάθε μήνα της ενημερώσεις “Patch Tuesday” και οι δημιουργοί malware παρακολουθούν αυτές τις μηνιαίες ενημερώσεις ασφαλείας για να επιλέξουν τις πιο χρήσιμες και επικίνδυνες ευπάθειες και να αλλάξουν τα στοιχεία των ενημερώσεων για να βρουν το ακριβές σφάλμα που διορθώθηκε από τη Microsoft. Αυτά τα σφάλματα μπορούν να τα χρησιμοποιήσουν για μελλοντικές επιθέσεις.
Οι διαχειριστές συστημάτων πρέπει να εξετάσουν την απειλή που θέτει κάθε μια από αυτές τις RCE ευπάθειες και, στη συνέχεια, να εφαρμόσουν το Patch Tuesday όσο πιο άμεσα γίνεται για να παραμείνουν ασφαλείς.
