Critico (76.66)

Sintesi

Microsoft ha rilasciato gli aggiornamenti di sicurezza mensili che risolvono un totale di 420 nuove vulnerabilità, di cui 1 di tipo 0-day.

Tipologia

  • Elevation of Privilege
  • Security Feature Bypass
  • Remote Code Execution
  • Spoofing
  • Information Disclosure
  • Tampering
  • Denial of Service

Descrizione e potenziali impatti

Nel dettaglio le vulnerabilità sfruttate attivamente o per le quali risulta disponibile in rete un “proof of concept”, riguardano:

  • Windows Ancillary Function Driver for WinSock: identificata tramite la CVE-2026-68820, di tipo “Use After Free” e con score CVSS v3.1 pari a 7, presente nel driver Windows Ancillary Function per WinSock. Tale vulnerabilità potrebbe consentire, a un utente autenticato localmente, l’esecuzione di un’applicazione opportunamente predisposta sul sistema interessato al fine di innescare una race condition e ottenere i privilegi di livello SYSTEM.
  • Windows Container Isolation FS Filter Driver (unionfs.sys): identificata tramite la CVE-2026-72971, di tipo “Tampering” e con score CVSS v3.1 pari a 5.5, interessa il driver Windows Container Isolation FS Filter ( unionfs.sys ). Tale vulnerabilità è dovuta a un’errata risoluzione dei link prima dell’accesso ai file ( link following ), e consentirebbe a un utente autenticato la possibilità di effettuare operazioni non autorizzate a livello locale.
  • Windows User Profile Service: identificata tramite la CVE-2026-62832, di tipo “Elevation of Privilege” e con score CVSS v3.1 pari a 7.8, interessa la componente Windows User Profile Service. La vulnerabilità è dovuta a un’errata risoluzione dei link prima dell’accesso ai file ( link following ): un utente locale in possesso delle credenziali di un secondo account (anch’esso locale) potrebbe sfruttare tale vulnerabilità eseguendo un’applicazione opportunamente predisposta al fine di caricare l’hive del registro del secondo utente, accedendo e/o modificando i dati di quest’ultimo e ottenendo potenzialmente privilegi amministrativi, senza che sia richiesta alcuna interazione da parte dell’utente interessato.
