Hard-coded x11vnc Password in HIPASE-250 Workstations

Executive Summary

This vulnerability involves a provisioning script for HIPASE-250 engineering workstations that sets a hard-coded, fixed x11vnc password. The same password is used across all workstations provisioned this way, allowing attackers with adjacent-network access to gain VNC control if they know the password.

Detection Guidance

Check for x11vnc service running on HIPASE-250 workstations with a hard-coded password. Use commands like 'netstat -tulnp | grep x11vnc' or 'ss -tulnp | grep x11vnc' to detect active VNC sessions. Inspect provisioning scripts for hard-coded credentials in x11vnc configurations.

Impact Analysis

An attacker with adjacent-network access could exploit this to gain unauthorized VNC access to your workstation, potentially allowing them to view or control your system remotely. This could lead to data theft, system manipulation, or further network compromise.

Compliance Impact

This vulnerability could violate compliance requirements that mandate secure access controls, such as GDPR's data protection principles or HIPAA's safeguards for protected health information. Unauthorized remote access risks exposing sensitive data, leading to potential legal and regulatory penalties.

Mitigation Strategies

Disable x11vnc service on affected workstations if not required. Replace the hard-coded password with a unique, strong password for each system. Restrict network access to VNC ports using firewalls. Update provisioning scripts to avoid hard-coded credentials.
