∗∗∗ Citrix forgot to tell you CVE-2025–6543 has been used as a zero day since May 2025 ∗∗∗ --------------------------------------------- Netscaler customers have a problem: the product is on fire. And not in a good way.

Applying patches after already being exploited is not working. --------------------------------------------- https://doublepulsar.com/citrix-forgot-to-tell-you-cve-2025-6543-has-been-us...

∗∗∗ Windows: Zero-Day-Lücke bei der LNK-Anzeige ∗∗∗ --------------------------------------------- Laut ZDI stellte Microsoft sich auf den Standpunkt, dass die Sicherheitslücke nicht den Schweregrad für eine Behandlung erreicht. Auch nach etwa einem halben Jahr hin und her änderte Microsoft seine Meinung dazu nicht. Schließlich hat ZDI die Meldung veröffentlicht und jetzt auch einen CVE-Schwachstelleneintrag dazu herausgegeben. [..] "Die Schwachstelle ermöglicht Angreifern aus dem Netz, beliebigen Code auf betroffenen Installationen von Microsoft Windows auszuführen. Benutzerinteraktion ist für den Missbrauch erforderlich, diese müssen eine bösartige Seite besuchen oder eine bösartige Datei öffnen", schlussfolgert die ZDI. [..] (CVE-2025-9491 / noch kein EUVD, CVSS 7.0, Risiko "hoch") --------------------------------------------- https://heise.de/-10625780
