Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The Process Optimization application suite leverages connection channels/protocols that by-default are not encrypted and could become subject to hijacking or data leakage in certain man-in-the-middle or passive inspection scenarios.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The Process Optimization application suite uses unencrypted connection channels/protocols by default, making communications vulnerable to man-in-the-middle attacks and passive inspection leading to potential data leakage or session hijacking.

MitigationImplement TLS/SSL encryption or equivalent cryptographic controls on all network communication channels used by the Process Optimization suite to protect data in transit.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check the installed version of Aveva Process Optimization
    Locate the Aveva Process Optimization installation and retrieve its version number (typically found in the application properties, about dialog, or installed programs list)
    Affected if The installed version is any version prior to 2025 (e.g., 2024, 2023, etc.)
  2. Verify if encryption is enabled for network communications
    Access the application configuration settings or network settings panel and examine whether TLS/SSL or equivalent encryption is configured for outbound and inbound communications
    Affected if Encryption is disabled or set to 'none' for any communication channel
  3. Identify communication protocols in use
    Review the application's protocol configuration (often found in network settings, connection settings, or communication profile settings) to determine which protocols are enabled for client-server or distributed communications
    Affected if Unencrypted protocols (such as plain HTTP, unencrypted TCP, or legacy protocols) are listed as enabled or preferred
  4. Inspect the configuration file for encryption settings
    Locate and examine the main configuration file(s) for Aveva Process Optimization (commonly found in the installation directory or config folder) and look for parameters related to transport security, SSL/TLS settings, or encryption flags
    Affected if Parameters indicating encryption is disabled, optional, or not configured are present
  5. Check system or service configuration for default connection settings
    Examine the service configuration, registry entries (if applicable), or administration console for default connection behavior to determine if the application defaults to unencrypted channels
    Affected if The application defaults to unencrypted connections or has no encryption enforced by default

The environment is affected if Aveva Process Optimization version is prior to 2025 AND unencrypted communication channels are in use or encryption is not explicitly configured/enabled.

Fixed in 2025
Interim mitigation

Implement TLS/SSL encryption or equivalent cryptographic controls on all network communication channels used by the Process Optimization suite to protect data in transit.

Recommended fix Moderate confidence

AVEVA Process Optimization 2025 or later

  1. 1. Back up the current Process Optimization configuration and database according to AVEVA backup procedures.
  2. 2. Review AVEVA Process Optimization 2025 release notes for any prerequisite updates or compatibility requirements.
  3. 3. Download AVEVA Process Optimization version 2025 or later from the AVEVA Customer Portal (software.aveva.com).
  4. 4. Stop all Process Optimization services and ensure no active sessions are running.
  5. 5. Install the Process Optimization 2025 update using the standard AVEVA installation wizard.
  6. 6. After installation, verify that encryption is enabled for all connection channels as per the 2025 release documentation.
  7. 7. Restart Process Optimization services and perform functional testing to confirm normal operation.
  8. 8. Validate that the cleartext transmission vulnerability is remediated by verifying encrypted communication channels.
Caveat Review upgrade compatibility with connected systems and any configuration changes required for encrypted channels in version 2025
