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
GE Gas Power ToolBoxST Version v04.07.05C suffers from an XML external entity (XXE) vulnerability using the DTD parameter entities technique that could result in disclosure and retrieval of arbitrary data on the affected node via an out-of-band (OOB) attack. The vulnerability is triggered when input passed to the XML parser is not sanitized while parsing the XML project/template file.

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 · high confidence

GE Gas Power ToolBoxST v04.07.05C contains an XML External Entity (XXE) vulnerability. The application fails to sanitize XML input when parsing project/template files, allowing attackers to inject malicious XML with external entity references using DTD parameter entities. This enables out-of-band data exfiltration from the affected system.

MitigationConfigure the XML parser to disable external entity resolution, DTD processing, and disable external DTDs. Validate and sanitize XML input before parsing.

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. Identify ToolBoxST installation and version
    Locate the GE Gas Power ToolBoxST installation directory and check the version information, typically found in the application properties, About dialog, or version file within the program folder.
    Affected if The installed version is ToolBoxST and is below version 07.09.7c
  2. Locate project and template files
    Search the system for .xml, .tpl, .gxml, or project file extensions used by ToolBoxST, typically stored in the application data folder or user-specified project directories.
    Affected if The application uses project or template files that contain XML data
  3. Verify XML parsing is active
    Monitor or inspect application logs and configuration to confirm that XML project/template file parsing is enabled and being used during normal operations.
    Affected if The application parses XML files from project/template functionality
  4. Check for untrusted XML input handling
    Review whether the application accepts or imports XML files from external sources, network locations, or untrusted user-provided files.
    Affected if The application processes XML input from external or untrusted sources without validation

You are affected if GE Gas Power ToolBoxST version is below 07.09.7c and the application parses XML project or template files, particularly from external or untrusted sources.

Upgrade available Upgrade to 07.09.07c or later
Fixed in 07.09.07c
Interim mitigation

Configure the XML parser to disable external entity resolution, DTD processing, and disable external DTDs. Validate and sanitize XML input before parsing.

Recommended fix High confidence

Upgrade to GE Gas Power ToolBoxST version 07.09.07c or later

  1. 1. Identify the current version of GE Gas Power ToolBoxST installed on the system
  2. 2. Compare the installed version against version 07.09.07c - versions prior to 07.09.07c are vulnerable
  3. 3. Obtain the fixed version (07.09.07c or later) from the official GE vendor channels or CISA advisory
  4. 4. Apply the upgrade following GE's standard upgrade procedures for ToolBoxST
  5. 5. Verify the upgraded version is 07.09.07c or later
  6. 6. Test that XML project/template file parsing functions correctly post-upgrade
