CVE-2026-65313 Use of hard-coded VNC credentials in the engineering-workstation provisioning

A provisioning script used when installing HIPASE-250 formerly 250 SCALA engineering workstations sets a fixed, hard-coded x11vnc password. Because the same credential is applied to every workstation provisioned this way, an attacker with adjacent-network access who knows the password can gain VN...
