Η Microsoft κυοφόρησε χθες το Patch Tuesday Οκτωβρίου 2022 φέρνοντας μια σειρά από διορθώσεις για 84 ευπάθειες. Μια από αυτές τις ευπάθειες έχει ήδη χρησιμοποιηθεί σε επιθέσεις από εγκληματίες του κυβερνοχώρου.
Δεκατρείς από τις 84 ευπάθειες που διορθώθηκαν ταξινομούνται ως “Κρίσιμες“, καθώς επιτρέπουν την απόκτηση περισσότερων προνομίων στα ευάλωτα συστήματα, την πλαστογράφηση ή την εκτέλεση κώδικα απομακρυσμένα.

Στην παρακάτω λίστα, μπορείτε να δείτε αναλυτικά το είδος των ευπαθειών που διορθώνονται με το Patch Tuesday Οκτωβρίου και τον αριθμό ανά κατηγορία:
Ανακαλύψτε το Νέο Ανθρωποειδές Ρομπότ GR-2!
- 39 ευπάθειες που επιτρέπουν την απόκτηση περισσότερων προνομίων
- 20 ευπάθειες που επιτρέπουν την εκτέλεση κώδικα απομακρυσμένα
- 11 ευπάθειες που επιτρέπουν την αποκάλυψη πληροφοριών
- 8 Ευπάθειες για Denial of Service επιθέσεις
- 4 Ευπάθειες spoofing
- 2 ευπάθειες που παρακάμπτουν τις λύσεις ασφαλείας
Οι παραπάνω ευπάθειες δεν περιλαμβάνουν τις δώδεκα ευπάθειες που διορθώθηκαν στον Microsoft Edge στις 3 Οκτωβρίου.
Microsoft Patch Tuesday: Διορθώνονται δύο zero-day ευπάθειες
Με το Patch Tuesday Οκτωβρίου, η Microsoft διορθώνει και δύο zero-day ευπάθειες. Η μια χρησιμοποιείται ενεργά σε επιθέσεις.
Η Microsoft ταξινομεί μια ευπάθεια ως zero-day εάν έχει αποκαλυφθεί δημόσια ή έχει γίνει ενεργή εκμετάλλευση, προτού κυκλοφορήσει επίσημη ενημέρωση κώδικα.

Η zero-day ευπάθεια που χρησιμοποιείται σε επιθέσεις, παρακολουθείται ως “CVE-2022-41033 – Windows COM+ Event Service System Elevation of Privilege Vulnerability“. Αυτή η ευπάθεια έχει βαθμολογία CVSSv3.1 7,8/10.
Η Microsoft δεν έχει αποκαλύψει πώς γίνεται η εκμετάλλευση της ευπάθειας ή εάν γίνεται εκμετάλλευση σε στοχευμένες ή πιο εκτεταμένες επιθέσεις. Έχει πει, όμως, ότι η πολυπλοκότητα της επίθεσης είναι χαμηλή. Η επιτυχημένη εκμετάλλευση της ευπάθειας θα μπορούσε να επιτρέψει σε ένα εισβολέα να αποκτήσει προνόμια SYSTEM, χωρίς να απαιτείται αλληλεπίδραση με τον χρήστη.
Η δεύτερη zero-day ευπάθεια παρακολουθείται ως “CVE-2022-41043 – Microsoft Office Information Disclosure Vulnerability“. Η Microsoft λέει ότι οι εισβολείς θα μπορούσαν να χρησιμοποιήσουν αυτήν την ευπάθεια για να αποκτήσουν πρόσβαση στα authentication tokens των χρηστών.
Οι δύο ευπάθειες zero-day στο Microsoft Exchange δεν διορθώθηκαν
Δυστυχώς, η Microsoft δεν έχει κυκλοφορήσει ενημερωμένες εκδόσεις ασφαλείας για δύο ευπάθειες zero-day που χρησιμοποιούνται ενεργά και παρακολουθούνται ως CVE-2022-41040 και CVE-2022-41082 (γνωστές και ως ProxyNotShell). Αυτές οι δύο ευπάθειες δεν διορθώνονται με το Microsoft Patch Tuesday Οκτωβρίου.

Αυτά τα σφάλματα αποκαλύφθηκαν στα τέλη Σεπτεμβρίου από τη βιετναμέζικη εταιρεία κυβερνοασφάλειας GTSC, η οποία εντόπισε και ανέφερε για πρώτη φορά τις επιθέσεις. Η Microsoft ενημερώθηκε για τις ευπάθειες μέσω του Zero Day Initiative της Trend Micro.
Ωστόσο, αυτές οι ευπάθειες δεν διορθώνονται με το νέο Patch Tuesday.
