CVE-2011-3302
HighSummary
Urządzenia Cisco Adaptive Security Appliances (ASA) serii 5500 oraz moduł usług ASA w urządzeniach Cisco Catalyst 6500 z określonymi wersjami oprogramowania są podatne na atak typu denial of service. Atakujący mogą spowodować ponowne uruchomienie urządzenia poprzez odpowiednio skonstruowany ruch SunRPC.
Risk Assessment
Podatność ta może prowadzić do przerwy w dostępności usług, co może wpłynąć na ciągłość działania organizacji. Atakujący mogą wykorzystać tę lukę do zakłócenia pracy urządzeń zabezpieczających.
Recommendation
Zaleca się aktualizację oprogramowania do najnowszych wersji, które eliminują tę podatność. Należy również monitorować ruch SunRPC w celu wykrywania potencjalnych prób ataku.

- CVE-2026-124494Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability because the html.clean() sanitizer's _normalizeURL() function decodes named entities like : to an empty string. Attackers can inject href values such as javascript: that pass the _isSafeURL() check but are decoded by browsers, executing JavaScript when victims click stored links.
- 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.
