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 HTTP API in ABBYY FlexiCapture before 12 Release 1 Update 7 allows an attacker to conduct Access Control attacks via the /FlexiCapture12/Login/Server/SevaUserProfile FlexiCaptureTmsSts2 parameter.

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

ABBYY FlexiCapture before version 12 Release 1 Update 7 contains an access control vulnerability in its HTTP API. The issue is located in the /FlexiCapture12/Login/Server/SevaUserProfile endpoint with the FlexiCaptureTmsSts2 parameter, which allows attackers to bypass authorization checks and potentially access sensitive functionality or data.

MitigationApply ABBYY FlexiCapture 12 Release 1 Update 7 or later to patch the access control vulnerability. Restrict network access to the HTTP API endpoints until the patch can be applied.

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. Determine installed FlexiCapture version
    Check the application's About or Help section, or inspect the installed binaries (FlexiCapture.exe or FlexiCapture12.Web.exe) by right-clicking and viewing Properties > Details to see the File Version. Alternatively, check the Windows Programs and Features list for the installed version number.
    Affected if The installed version matches one of the affected builds: 12.0.1.263, 12.0.1.267, 12.0.1.282, 12.0.1.292, 12.0.1.367, 12.0.1.428, or 12.0.1.475, or is any version earlier than 12 Release 1 Update 7.
  2. Verify HTTP API is enabled
    Confirm that the FlexiCapture Web server component (FlexiCapture12 Web Server) is installed and running. Check IIS Manager for the FlexiCapture12 website/application pool, or look for the FlexiCapture12 Web site binding in IIS.
    Affected if The FlexiCapture12 web interface or HTTP API is enabled and accessible.
  3. Check network exposure of the API
    Review firewall rules, IIS bindings, and network configuration to determine if the FlexiCapture12 web endpoints are reachable from untrusted networks. Use netstat or Test-NetConnection to identify listening ports (typically 80 or 443 for the web API).
    Affected if The /FlexiCapture12/ Login/Server/SevaUserProfile endpoint is exposed to the internet or untrusted internal networks.
  4. Inspect the specific vulnerable endpoint
    Attempt a GET or POST request to http(s)://<server>/FlexiCapture12/Login/Server/SevaUserProfile and observe whether the application responds (even with an error) versus rejecting the request outright. Check IIS logs for access attempts to this endpoint.
    Affected if The endpoint responds to requests, indicating the API is active and potentially vulnerable to the authorization bypass.

You are affected if FlexiCapture 12 is installed with any version earlier than Release 1 Update 7 AND the HTTP API/web interface is enabled and accessible to untrusted users.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply ABBYY FlexiCapture 12 Release 1 Update 7 or later to patch the access control vulnerability. Restrict network access to the HTTP API endpoints until the patch can be applied.

Recommended fix Moderate confidence

ABBYY FlexiCapture 12 Release 1 Update 7 or later

  1. 1. Verify current FlexiCapture installation version by checking the application or control panel
  2. 2. Download ABBYY FlexiCapture 12 Release 1 Update 7 or later from the official ABBYY downloads portal (abbyydownloads.com)
  3. 3. Create a complete backup of the current FlexiCapture database and configuration files
  4. 4. Stop all FlexiCapture services before beginning the upgrade process
  5. 5. Run the installer for the new version, following the on-screen prompts
  6. 6. After installation completes, verify that all services start correctly
  7. 7. Test the /FlexiCapture12/Login/Server/SevaUserProfile endpoint to confirm the access control vulnerability is resolved
  8. 8. Verify that existing workflows and integrations function properly
