CVE-2011-1966
HighSummary
Serwer DNS w systemie Microsoft Windows Server 2008 SP2, R2 i R2 SP1 nieprawidłowo obsługuje zapytania NAPTR, co prowadzi do wywołania przetwarzania rekurencyjnego. To umożliwia zdalnym atakującym wykonanie dowolnego kodu poprzez spreparowane zapytanie.
Risk Assessment
Podatność ta stwarza poważne ryzyko dla organizacji, ponieważ umożliwia zdalne wykonanie kodu, co może prowadzić do przejęcia kontroli nad systemem. Atakujący mogą wykorzystać tę lukę do wprowadzenia złośliwego oprogramowania lub kradzieży danych.
Recommendation
Zaleca się aktualizację systemu do najnowszej wersji, aby załatać tę podatność. Dodatkowo, warto monitorować ruch DNS w celu wykrywania podejrzanych zapytań.

- CVE-2026-124493Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability in the DocumentType constructor that injects header textContent into innerHTML without HTML escaping. Attackers can store entity-encoded HTML in h1-h6 headers that executes JavaScript when editors using document:header mode initialize, enabling session cookie theft.
Original NVD description (English source)
The DNS server in Microsoft Windows Server 2008 SP2, R2, and R2 SP1 does not properly handle NAPTR queries that trigger recursive processing, which allows remote attackers to execute arbitrary code via a crafted query, aka "DNS NAPTR Query Vulnerability."
