Citrix confirms exploitation of CVE-2026-88771 and CVE-2026-88772. My updated NetScaler checklist covers all eight CVEs and includes a read-only triage script. A clean scan does not prove an appliance is uncompromised. www.deyda.net/index.php/en... #DeydaConsulting #NetScaler #Citrix

A new day, a new LAS topic If you suddenly see multiple catalogs going unregistered after migrating to Citrix License Activation Service and your event logs show: "NotLicensedForFeature" Check if Multi-Type Licensing is enabled. shorturl.at/2Nvs8

Many @citrix.bsky.social admins see “Blue” after LAS registration and think: “Done.” Nope. 😅 Blue ≠ Activated. A practical guide to migrating CVAD, WEM & NetScaler to LAS before the April 2026 license cutoff 👇 shorturl.at/2Nvs8 #citrix #las #netscaler #15april

Citrix License Activation Service (LAS): Goodbye License Files
If you're a Citrix customer and thinking “next week…” right now — understandable. But starting April 15, 2026, file-based Citrix license files will no longer work. This is not a warning; it’s a hard shutdown date. That means: if you haven’t migrated to LAS by then, you risk real outages (apps, desktops, or features depending on the component and version).

Citrix License Activation Service (LAS): Schluss mit License-Files
Wenn du als Citrix Kunde gerade "nächste Woche…" denkst: verständlich. Aber ab dem 15. April 2026 funktionieren file-basierte Citrix License-Files nicht mehr – das ist keine Drohung, das ist ein Abschaltdatum. Heißt: Wer bis dahin nicht auf LAS umgestellt hat, riskiert echte Ausfälle (Apps/Desktops/Features je nach Komponente und Version). LAS ist dabei keine "Cloud-Migration" deiner Workloads – du betreibst deine Site weiter on-prem (DDCs, StoreFront, VDAs etc.).

⚠️ January 2026 @Windows updates break Remote Assistance (msra.exe) and @Citrix Director Shadowing with it. Invites are created, downloaded… and instantly fail. There’s an unsupported workaround, but it reintroduces the security risk. bit.ly/4aCToBd #Windows #Citrix

Workaround für Remote Assistance Fehler
Nach der Installation der Microsoft-Sicherheitsupdates vom Januar 2026 funktioniert Windows Remote Assistance (msra.exe) auf mehreren Windows-Versionen nicht mehr. Dies betrifft direkt das Citrix Director Shadowing, da die generierten Einladungsdateien auf gepatchten Systemen nicht mehr geöffnet werden können. Ursache ist eine sicherheitsrelevante Härtung im Zusammenhang mit CVE-2026-20824 – Windows Remote Assistance Security Feature Bypass Vulnerability. Obwohl der Fix aus Sicherheitssicht nachvollziehbar ist, unterbricht er aktuell legitime Remote-Assistance-Workflows in Enterprise-Umgebungen.
