Microsoft Patch Tuesday – czerwiec 2026, wydany 9 czerwca 2026 r., obejmuje poprawki dla około 200 podatności w całym ekosystemie Microsoftu, co czyni go jednym z większych wydań w ostatnim czasie.
Wśród nich znajduje się 33 podatności krytyczne, z których większość dotyczy zdalnego wykonania kodu (RCE) – najgroźniejszego scenariusza ataku.
Szczególnie istotne są 3 podatności typu zero-day, które były publicznie znane przed wydaniem poprawek, co znacząco zwiększa ryzyko ich wykorzystania.
Problemy obejmują kluczowe komponenty, takie jak Windows, Active Directory, Hyper‑V, Remote Desktop oraz usługi HTTP, co oznacza szeroki wpływ na środowiska enterprise.
Najważniejsze podatności
1. Podniesienie uprawnień w Windows CTFMON (CVE-2026-45586)
Podatność umożliwia uzyskanie uprawnień SYSTEM poprzez błąd w obsłudze linków w Windows Collaborative Translation Framework.
Jest szczególnie groźna w scenariuszach po uzyskaniu dostępu do systemu, ponieważ pozwala atakującemu przejąć pełną kontrolę nad hostem.
2. Obejście zabezpieczeń BitLocker (CVE-2026-50507)
Luka pozwala na ominięcie mechanizmu szyfrowania BitLocker, osłabiając ochronę danych przechowywanych na dysku.
Stanowi to poważne zagrożenie w przypadku fizycznego dostępu do urządzenia, np. jego utraty lub kradzieży.
3. Denial of Service w HTTP.sys (CVE-2026-49160)
Podatność w stosie HTTP/2 systemu Windows umożliwia zakłócenie dostępności usług (DoS) poprzez specjalnie przygotowane żądania.
Ponieważ HTTP.sys jest podstawą działania IIS i innych usług sieciowych, problem dotyczy bezpośrednio serwerów dostępnych z Internetu.
4. Wiele podatności typu Remote Code Execution (RCE)
Aktualizacja usuwa 55 luk RCE, m.in. w komponentach takich jak Remote Desktop, Hyper‑V, Kerberos czy Active Directory.
Ich wykorzystanie może umożliwić zdalne wykonanie kodu, a w konsekwencji przejęcie systemów i rozprzestrzenianie się ataku w sieci.
