81b1c326fc Security: WS-Rollenprüfung, JWT-Cookie statt localStorage, XSS/SSRF-Fixes, RDP-Consent-Secret
Some checks failed
IT Nexus Deploy / Build Frontend (push) Has been cancelled
Details
IT Nexus Deploy / Deploy to Production (push) Has been cancelled
Details 
- WebSocket Shell/RDP: Rollenprüfung statt nur JWT-Gültigkeit (war: jeder eingeloggte User konnte fremde Agents per Shell/RDP übernehmen)
- JWT_SECRET: Server bricht ab statt mit unsicherem Default weiterzulaufen
- Auth: Token läuft jetzt über httpOnly-Cookie statt localStorage (XSS-Schutz gegen Session-Diebstahl)
- WS-Auth: Token nicht mehr als URL-Query-Param (landete in nginx-Logs), sondern als erste Message bzw. automatisch via Cookie
- Frontend: toter Rollen-Check (isSuperAdmin/isAdmin ohne Funktionsaufruf) in AgentDetailPage gefixt
- XSS: DOMPurify-Sanitizing für alle marked.parse()-Renderstellen (KI-Antworten, Kommentare, Knowledge Base)
- E-Mail: HTML-Escaping für alle ticket-gesteuerten Felder (auch über öffentliche Ticket-Route erreichbar)
- SSRF-Schutz beim Knowledge-Base-URL-Import (blockt private/Loopback-Adressen)
- TV-Dashboard: Shared-Key statt komplett offenem Endpoint
- Striktes Rate-Limit auf /login, must_change_password serverseitig erzwungen
- Agent (C#) v2.7.0: RDP-Consent/Disconnect/Capture verlangen jetzt ein Pro-Session-Secret (war: jeder lokale Prozess konnte Consent vortäuschen), DataDir-ACL für agent.log/status.json
- FIDO-PINs AES-256-GCM-verschlüsselt statt Klartext, Retention-Job für alte patch_commands/audit_log

99830e25f4 Fix: Remote Desktop — 60fps, Screen-Wechsel live, Consent-Dialog sichtbar (v2.3.0) 
- CaptureModeRunner: Thread.Sleep(150) → 16ms (~60fps) + Skip-if-unchanged via Pixel-Hash
- RtcService: rdp_switch_screen Handler — Screen wechseln ohne Consent-Dialog
- RtcService: Fallback bei Consent-Fehler → rdp_denied statt silent capture
- RdpConsentWindow: WindowStyle=ToolWindow + ShowInTaskbar=True (jetzt in Taskleiste sichtbar)
- RemoteDesktopPanel: Screen-Dropdown auch während aktiver Verbindung nutzbar
- Version: 2.2.0 → 2.3.0

058f968af1 Add Remote Desktop screen selector + new-tab button (v2.2.0) 
- CaptureModeRunner: screen index param (0=all, 1-N=specific monitor)
- RtcService: reads screen from rdp_start JSON, passes to capture helper
- Program.cs: parses optional screen index arg for --rdp-capture
- RemoteDesktopPanel: screen dropdown (Alle/1-4), new-tab button
- RdpPage: fullscreen standalone page at /rdp/:agentId
- AgentDetailPage: removed dead _RemoteDesktopOld_unused code

0b76ef3bfd Fix pipe ACL: switch from named pipe to TCP loopback 
Named pipe created by SYSTEM service denied connection from user process.
TCP loopback socket (127.0.0.1:random) has no cross-session ACL issues.

45f4c7846e Fix Session 0 issue: spawn screen capture helper in user session 
- CaptureModeRunner: captures desktop in user session via schtasks,
  sends JPEG frames over named pipe to service
- RtcService: creates named pipe server, spawns helper via schtasks
  (same pattern as NotificationService), reads frames and forwards to WS
- Program.cs: added --rdp-capture <pipeName> mode
- Multi-monitor: captures all screens combined
