Check Point Flags Citrix NetScaler and Cisco SD-WAN Vulnerabilities in Weekly Threat Bulletin

Check Point Research · 5 Oct 2026

Key Takeaway If your business uses Citrix NetScaler or Cisco Catalyst SD-WAN Manager, check the vendor advisories for these CVEs and ask your IT provider to confirm patching and protections are in place.

Check Point Research has released its weekly Threat Intelligence Bulletin for the week of 5th October. The opening of the report points readers to a full download for the latest cyber research findings, and only a small part of the content is covered here.

The excerpt names two groups of vulnerabilities. The first affects multiple Citrix NetScaler products: a buffer overflow (CVE-2026-88772) and a command injection flaw (CVE-2026-88771). The second is an authentication bypass in Cisco Catalyst SD-WAN Manager (CVE-2026-76504). Check Point says its IPS (intrusion prevention system) provides protection against all three.

The excerpt does not say whether these flaws are being exploited, how severe they are, or whether patches are available. Businesses that use Citrix NetScaler or Cisco Catalyst SD-WAN Manager should read the full bulletin and check vendor advisories for details. Network gateways and management tools are often exposed to the internet, so they are worth confirming and reviewing promptly.
