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
An arbitrary file upload vulnerability in the profile picture upload function of Exact Synergy Enterprise 267 before 267SP13 and Exact Synergy Enterprise 500 before 500SP6 allows attackers to execute arbitrary code via a crafted SVG 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

Exact Synergy Enterprise allows users to upload profile pictures through a web interface. The application fails to properly validate uploaded SVG files, which can contain embedded JavaScript or malicious XML content. When a crafted SVG file is uploaded, it can be executed in the context of the application, leading to arbitrary code execution on the server.

MitigationImplement strict validation of file uploads - reject SVG files or parse and sanitize SVG content to remove any embedded scripts, JavaScript, or external entity references. Additionally, serve uploaded files from a non-executable directory or use a content-disposition: attachment header.

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 Exact Synergy installation and version
    Locate the Exact Synergy application in your environment and determine the installed version number. Check installation directories, application metadata, or administrative console for version information.
    Affected if Version is 267 or 500 ( Exact Synergy )
  2. Confirm profile picture upload feature exists
    Access the Exact Synergy web interface and navigate to user profile settings to verify if a profile picture upload function is available.
    Affected if The profile picture upload feature is present and accessible to users
  3. Verify SVG upload acceptance
    Attempt to upload a test SVG file through the profile picture upload function, or examine the application's file type validation logic in the upload handler configuration.
    Affected if SVG files are accepted by the upload validation without sanitization or rejection
  4. Check uploaded file serving method
    Inspect how the application serves uploaded profile pictures - check if files are served with content-disposition: attachment header or from a non-executable directory.
    Affected if Uploaded files are served inline (without content-disposition: attachment) and are accessible via the web application

A user is affected if they are running Exact Synergy versions 267 or 500, the profile picture upload feature is enabled, and SVG files can be uploaded without proper validation or sanitization.

Mitigation

Implement strict validation of file uploads - reject SVG files or parse and sanitize SVG content to remove any embedded scripts, JavaScript, or external entity references. Additionally, serve uploaded files from a non-executable directory or use a content-disposition: attachment header.

Recommended fix High confidence

Exact Synergy Enterprise 267SP13 or Exact Synergy Enterprise 500SP6 (depending on your current version)

  1. Identify the current Exact Synergy Enterprise version (267 or 500) by checking the system information or help/about section
  2. For Exact Synergy Enterprise 267: Upgrade to version 267SP13 or later
  3. For Exact Synergy Enterprise 500: Upgrade to version 500SP6 or later
  4. After upgrading, verify that the profile picture upload function properly sanitizes SVG files and blocks malicious content
  5. Test the profile picture upload with a legitimate image to confirm functionality works correctly
