Η Microsoft κυκλοφόρησε χθες το Patch Tuesday Μαΐου 2022, φέρνοντας διορθώσεις για 75 ευπάθειες ασφαλείας. Από αυτές τις ευπάθειες, οι τρεις είναι zero-day, με τη μια να χρησιμοποιείται ήδη σε επιθέσεις.
Όσον αφορά στη σοβαρότητα των σφαλμάτων που διορθώνονται, οι οκτώ έχουν ταξινομηθεί ως “Κρίσιμες“, καθώς επιτρέπουν την εκτέλεση κώδικα απομακρυσμένα ή την αύξηση των προνομίων στα ευάλωτα συστήματα.
Στην παρακάτω λίστα, μπορείτε να δείτε το είδος των ευπαθειών που διορθώνονται αυτό το μήνα με το Microsoft Patch Tuesday:
- 26 ευπάθειες που επιτρέπουν εκτέλεση κώδικα απομακρυσμένα
- 21 ευπάθειες που δίνουν περισσότερα προνόμια στα ευάλωτα συστήματα
- 17 ευπάθειες που επιτρέπουν την αποκάλυψη πληροφοριών
- 6 ευπάθειες Denial of Service
- 4 ευπάθειες που επιτρέπουν την παράκαμψη λειτουργιών ασφαλείας
- 1 ευπάθεια Spoofing
Microsoft Patch Tuesday: Διορθώνονται τρεις zero-day ευπάθειες
Όπως είπαμε παραπάνω, το Patch Tuesday Μαΐου διορθώνει τρεις ευπάθειες zero-day, με τη μία να χρησιμοποιείται σε επιθέσεις και τις άλλες δύο να αποκαλύπτονται δημόσια.
Σύμφωνα με τη Microsoft, μια ευπάθεια είναι zero-day όταν αποκαλύπτεται δημόσια ή όταν γίνεται ενεργή εκμετάλλευση, χωρίς να έχει κυκλοφορήσει καμία επίσημη ενημέρωση κώδικα.
- CVE-2022-26925: Η ευπάθεια που χρησιμοποιείται ήδη. Πρόκειται για ένα σοβαρό σφάλμα που επιτρέπει στους κακόβουλους φορείς να υποκλέψουν νόμιμα authentication requests και να τα χρησιμοποιήσουν για να αποκτήσουν αυξημένα προνόμια. Η Microsoft έδωσε στο σφάλμα βαθμολογία σοβαρότητας CVSS 8,1, αλλά σημείωσε ότι εάν συνδυαζόταν με επιθέσεις NTLM relay, η σοβαρότητα θα ανέβαινε στο 9,8. Περισσότερες λεπτομέρειες εδώ.
- CVE-2022-22713: Denial of Service ευπάθεια στο Windows Hyper-V
- CVE-2022-29972: Insight Software: CVE-2022-29972 Magnitude Simba Amazon Redshift ODBC Driver
Η Microsoft συνιστά σε όλους τους χρήστες και τους διαχειριστές να εγκαταστήσουν το Patch Tuesday όσο το δυνατόν πιο γρήγορα, γιατί οι επιτιθέμενοι θα αρχίσουν να δημιουργούν exploits για τις ευπάθειες που έχουν γίνει τώρα γνωστές.
