NVD · unedited
Authorization Bypass Through User-Controlled Key, Improper Authorization vulnerability in Bimser Solution Software Trade Inc. EBA Document and Workflow Management System allows Forceful Browsing. This issue affects eBA Document and Workflow Management System: from 6.7.164 before 6.7.166.

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 vulnerability is an authorization bypass (CWE-639) in Bimser EBA Document and Workflow Management System where an attacker can perform forceful browsing to access restricted documents or workflow resources by manipulating user-controlled keys. This allows unauthorized access to functionality or data that should require proper authentication and authorization. The issue exists in versions from 6.7.164 before 6.7.166.

MitigationUpgrade to version 6.7.166 or later which contains the security fix. If immediate patching is not possible, implement additional access control validation at the application layer to ensure all resource access requests properly validate user permissions against the requested object.

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 Bimser EBA version
    Locate the installed version of Bimser EBA Document and Workflow Management System by checking the application metadata, about page, or system information panel within the software itself
    Affected if The installed version is 6.7.164 or 6.7.165 (any version from 6.7.164 up to but not including 6.7.166)
  2. Confirm document management module is active
    Verify that the Document Management System module is enabled and accessible within the Bimser EBA environment
    Affected if The document management module is in use and accessible to users
  3. Verify workflow resources are accessible
    Attempt to access workflow resources and documents within the system to confirm the workflow management functionality is operational
    Affected if Workflow resources can be accessed through the application interface
  4. Check for authorization controls on document access
    Inspect the application access control configuration or logs to determine if resource access requests properly validate user permissions against requested objects
    Affected if Authorization bypass is possible by manipulating user-controlled keys to access restricted documents or workflows without proper authentication validation

The environment is affected if Bimser EBA version is between 6.7.164 and 6.7.165 inclusive, and the document/workflow management modules are accessible and can be reached via unauthorized access through key manipulation.

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

Upgrade to version 6.7.166 or later which contains the security fix. If immediate patching is not possible, implement additional access control validation at the application layer to ensure all resource access requests properly validate user permissions against the requested object.

Recommended fix Moderate confidence

Upgrade to version 6.7.166 or later

  1. 1. Identify all deployments of Bimser EBA Document and Workflow Management System in the environment
  2. 2. Check current version of each deployment to confirm if running a version between 6.7.164 and 6.7.165 (inclusive)
  3. 3. Review upgrade documentation provided by Bimser Solution Software Trade Inc.
  4. 4. Create a backup of the current system configuration and database
  5. 5. Schedule a maintenance window for the upgrade
  6. 6. Upgrade Bimser EBA Document and Workflow Management System to version 6.7.166 or later
  7. 7. Verify the upgrade was successful by checking the new version number
  8. 8. Test that the authorization bypass vulnerability is no longer exploitable
Caveat Review Bimser release notes for version 6.7.166 to check for any breaking changes or new features that may affect existing workflows
