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
