Citrix Netscaler Security issue

What do I need to know? On Tuesday 18 July, Citrix published a security bulletin warning users of three new vulnerabilities affecting NetScaler ADC and NetScaler Gateway. See below for more details.  


Of the three vulnerabilities, CVE-2023-3519 is the most severe — successful exploitation allows unauthenticated attackers to execute code remotely on vulnerable target systems that are configured as a Gateway.

What do I need to do? Don’t panic! We patched all of our customers who have a Patching and Monitoring Service in place or who are a Private Cloud customer to protect them against this security vulnerability by the close of play on Wednesday 19 July.

The vulnerability was 9.8/10 on CVSS, so significant, probably the highest we’ve seen in a while.  This only affected customers with Citrix.

For more information on any of the above, please contact your Connect Systems Account Manager or get in touch with us here and we’ll be happy to help you.
