NI SystemLink Enterprise EUVD-2026-33411

Apply the fixed release identified in NI's security advisory at https://www.ni.com/en/support/security/available-critical-and-security-updates-for-ni-software/2026/authentication-bypass-vulnerability-in-ni-systemlink-enterprise.html; the input data does not include an exact patched version string, so treat this as patch available per vendor advisory and confirm the target version directly with NI before deployment. Until upgraded, restrict network reachability of the SystemLink Enterprise Dashboard to trusted management subnets via firewall or reverse-proxy ACLs and require VPN access, accepting that this removes broad engineer access from untrusted networks. Place the Dashboard behind an authenticating reverse proxy (for example an SSO-enforcing gateway) so that the vulnerable HTTP endpoints are not directly reachable, noting that this may break clients that bypass the proxy. Increase HTTP access logging and alert on anonymous requests reaching authenticated paths so any exploitation attempts before patching are visible.
