CVE-2026-3314

Executive Summary

CVE-2026-3314 is a Missing Password Field Masking vulnerability affecting multiple Hitachi products: Ops Center Analyzer, Ops Center Analyzer viewpoint, and Infrastructure Analytics Advisor. The vulnerability allows an attacker with local access or the ability to observe a user's screen to visually capture plaintext passwords displayed in unmasked input fields. This is a local information disclosure issue with a CVSS score of 4.6 (Medium). No public proof-of-concept or exploit code is available, and the EPSS score is 0.0%, indicating very low exploitation activity in the wild. The vendor has released a patch (version 11.0.8-00) to address the issue.

Supply Chain & Package Security

This vulnerability is not related to any open-source package manager (NPM, PyPI, Go, Ruby). It affects proprietary Hitachi enterprise software. No supply chain implications are present.

CVSS Breakdown & Threat Level

• CVSS Score: 4.6 (Medium)
• Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N
• Attack Vector: Local (AV:L) – The attacker must have physical or remote desktop access to the system.
• Attack Complexity: Low (AC:L) – No special conditions required.
• Privileges Required: None (PR:N) – The attacker does not need prior authentication.
• User Interaction: Required (UI:R) – The victim must be using the application and the attacker must observe the screen.
• Scope: Unchanged (S:U) – The vulnerability does not affect other components.
• Confidentiality Impact: High (C:H) – Plaintext passwords are exposed.
• Integrity Impact: None (I:N)
• Availability Impact: None (A:N)

Threat Level: Low to Medium. The vulnerability requires local access and user interaction, making it less likely to be exploited remotely. However, in shared workstation environments or during screen-sharing sessions, the risk increases.

Deep Dive & Mechanics

The vulnerability exists in the user interface components of Hitachi Ops Center Analyzer, Ops Center Analyzer viewpoint, and Infrastructure Analytics Advisor. When users enter passwords in certain forms (e.g., detail views, probe module configuration, analytics probe modules), the password field does not mask the input. Instead of displaying asterisks or dots, the characters are shown in plaintext.

Root Cause: The application fails to set the type="password" attribute on HTML input fields or equivalent UI controls. This is a classic CWE-549 (Missing Password Field Masking) issue.

Attack Scenario:

1. An attacker gains local access to a system running the vulnerable software (e.g., via shoulder surfing, screen recording, or remote desktop monitoring).
2. The victim logs into the Hitachi application and enters a password in an unmasked field.
3. The attacker visually captures the password.
4. The attacker can then use the stolen credentials to gain unauthorized access to the system.

Affected Components:

• Hitachi Ops Center Analyzer: detail view, probe modules
• Hitachi Ops Center Analyzer viewpoint
• Hitachi Infrastructure Analytics Advisor: Data Center Analytics, Analytics probe modules

Affected Versions:

• Ops Center Analyzer: 10.0.0-00 to 11.0.7-xx
• Ops Center Analyzer viewpoint: 10.8.1-00 to 11.0.7-xx
• Infrastructure Analytics Advisor: 3.2.0-00 to 11.0.7-xx

Vulnerable vs. Patched Code

Since this is a proprietary software, exact code snippets are not available. However, the fix involves changing the input field type from text to password in the UI.

Vulnerable (Conceptual):

<input type="text" id="password" name="password">

Patched (Conceptual):

<input type="password" id="password" name="password">

The patched version (11.0.8-00) ensures all password fields are masked by default.

Exploitation & Lab Setup

Red Team (Attacker)

Prerequisites:

• Local access to a system running a vulnerable version of the software.
• Ability to observe the screen (physical or via screen-sharing software).

Steps:

1. Identify the target system running Hitachi Ops Center Analyzer (e.g., via Shodan dork: Hitachi Ops Center Analyzer).
2. Gain local access via social engineering, physical access, or compromised remote desktop.
3. Wait for a user to log in and enter a password in an unmasked field.
4. Visually capture the password (e.g., take a screenshot or record the screen).
5. Use the stolen credentials for lateral movement or privilege escalation.

No exploit code is available. This is a UI design flaw, not a code injection vulnerability.

Blue Team (Defender)

Detection:

• Monitor for unauthorized local access attempts.
• Use screen recording detection tools (e.g., detect scrot, gnome-screenshot, or xwd usage).
• Implement session recording alerts for sensitive applications.

Prevention:

• Apply the vendor patch (upgrade to version 11.0.8-00).
• Enforce the use of password managers that auto-fill masked fields.
• Implement screen privacy filters on monitors.
• Restrict local access to authorized personnel only.

Indicators of Compromise (IOCs)

• Network: No specific network IOCs (local vulnerability).
• Host:
  • Presence of screen capture tools (e.g., scrot, import, gnome-screenshot).
  • Unauthorized remote desktop sessions (e.g., VNC, RDP).
  • Logs showing repeated failed login attempts after password exposure.
• File: No specific file-based IOCs.

Remediation & Mitigation

Immediate Actions:

1. Upgrade all affected products to version 11.0.8-00 or later.
   • Hitachi Ops Center Analyzer: Upgrade from any 10.x or 11.0.x before 11.0.8-00.
   • Hitachi Ops Center Analyzer viewpoint: Upgrade from any 10.8.x or 11.0.x before 11.0.8-00.
   • Hitachi Infrastructure Analytics Advisor: Upgrade from any 3.2.x or 11.0.x before 11.0.8-00.
2. Verify the patch by checking the version number in the application's About dialog.

Compensating Controls:

• Enable screen privacy filters on all monitors.
• Restrict physical and remote desktop access to authorized personnel.
• Use password managers to auto-fill credentials, reducing manual entry.
• Implement session recording and monitoring for sensitive applications.
• Conduct security awareness training on shoulder surfing risks.

Long-Term:

• Ensure all future UI components use type="password" for password fields.
• Perform regular security audits of UI code.
