CVE-2023-6548
Authenticated (low privileged) remote code execution on Management Interface
Access to NSIP, CLIP or SNIP with management interface access
CVE- 2023- 6548 only impacts the management interface. Cloud Software Group strongly recommends that network traffic to the appliance’s management interface is separated, either physically or logically, from normal network traffic. In addition, we recommend that you do not expose the management interface to the internet, as explained in the secure deployment guide. Removing such exposure to the internet greatly reduces the risk of exploitation of this issue. See NetScaler secure deployment guide ( https://docs.citrix.com/en-us/citrix-adc/citrix-adc-secure-deployment/secure-deployment-guide.html) for more information.
