Citrix NetScaler and Cisco SD-WAN zero-days under active exploitation
Original: OT Security Weekly DACH – KW 40/2026: Edge Zero-Days in Remote Access Citrix NetScaler and Cisco SD-WAN Manager zero-day
Security teams in the DACH region are being warned about newly disclosed zero-day vulnerabilities in Citrix NetScaler remote access products and Cisco SD-WAN Manager. Both flaws are reported to be actively exploited in the wild, putting operational technology environments at particular risk through exposed remote access points. Practitioners are urged to patch immediately, hunt for signs of compromise and review edge device exposure this week.
Why now: Actively exploited zero-days in widely used edge and remote access products create urgent patching pressure for critical infrastructure operators.
