Il Patch Tuesday di ottobre 2023 di Microsoft ha portato con sé aggiornamenti di sicurezza per 104 difetti, tra cui tre vulnerabilità zero-day attivamente sfruttate. Di questi, ben quarantacinque sono bug di esecuzione di codice remoto (RCE), ma solo dodici sono stati classificati come “Critici” da Microsoft, tutti rientranti nella categoria RCE.
Ecco una ripartizione delle vulnerabilità per categoria:
- Elevazione dei privilegi: 26 vulnerabilità
- Bypass delle funzionalità di sicurezza: 3 vulnerabilità
- Esecuzione di codice remoto: 45 vulnerabilità
- Divulgazione di informazioni: 12 vulnerabilità
- Denial of Service: 17 vulnerabilità
- Spoofing: 1 vulnerabilità
Va notato che il totale di 104 difetti non comprende una vulnerabilità di Chromium, identificata come CVE-2023-5346, che Google ha corretto il 3 ottobre e che è stata successivamente integrata in Microsoft Edge.
Focus sulle vulnerabilità zero-day Questo mese, Microsoft ha affrontato tre vulnerabilità zero-day:
- CVE-2023-41763 – Questa vulnerabilità riguarda Skype for Business ed è classificata come un bug di elevazione dei privilegi. È stato rivelato che Microsoft aveva precedentemente rifiutato di correggere questo difetto, nonostante fosse stato segnalato nel settembre 2022.
- CVE-2023-36563 – Questa vulnerabilità in Microsoft WordPad può essere sfruttata per rubare hash NTLM quando si apre un documento con il programma.
- CVE-2023-44487 – Conosciuto come “HTTP/2 Rapid Reset”, questo nuovo metodo di attacco DDoS ha infranto tutti i record precedenti di attacchi di questo tipo.
Aggiornamenti da altri fornitori Oltre a Microsoft, altri fornitori hanno rilasciato aggiornamenti o avvisi nel mese di ottobre 2023:
- Apple ha corretto due vulnerabilità zero-day con iOS 17.0.3.
- Arm ha segnalato nuovi difetti nella GPU Mali.
- Cisco ha rilasciato aggiornamenti per vari prodotti.
- Citrix ha corretto un difetto in Citrix NetScaler ADC e Gateway.
- D-Link ha rilasciato dettagli tecnici per un zero-day nel suo range extender WiFi 6 DAP-X1860.
- Exim ha patchato tre dei sei zero-day segnalati.
- Google ha rilasciato gli aggiornamenti di sicurezza di Android per ottobre 2023.
- GNOME ha un difetto RCE.
- Un nuovo attacco zero-day, “HTTP/2 Rapid Reset”, ha stabilito nuovi record DDoS.
- Diverse distribuzioni Linux sono vulnerabili a causa di un bug chiamato “Looney Tunables”.
- Microsoft ha anche rilasciato un aggiornamento d’emergenza per Edge e Teams.
- SAP ha rilasciato gli aggiornamenti di Patch Day di ottobre 2023.
- Nuovi difetti, noti come ShellTorch, influenzano lo strumento open-source TorchServe AI model-serving.
Con la crescente complessità e interconnessione dei sistemi, è essenziale che aziende e individui si mantengano aggiornati sugli ultimi sviluppi in materia di sicurezza e applichino tempestivamente gli aggiornamenti necessari per proteggere le proprie risorse digitali.
