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
IBM Controller 11.1.0 through 11.1.1 and IBM Cognos Controller 11.0.0 through 11.0.1 FP6 could allow an authenticated user to cause a denial of service due to improper validation of a specified quantity size input.

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

IBM Controller 11.1.0-11.1.1 and Cognos Controller 11.0.0-11.0.1 FP6 contain a DoS vulnerability where authenticated users can trigger a denial of service by providing improperly validated quantity size input, likely causing the application to crash or become unresponsive.

MitigationImplement robust server-side validation for quantity size inputs to ensure values are within acceptable bounds and of the correct data type before processing.

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 the installed product and version
    Check the IBM Controller or Cognos Controller installation. This is typically found in the program's 'About' section, in the installation directory's version file, or by querying the application through its administration interface. Common locations include the 'about' dialog in the software or registry entries under HKLM\Software\IBM\Cognos\Controller (Windows).
    Affected if The installed version is IBM Controller 11.1.0 through 11.1.1, or IBM Cognos Controller 11.0.0 through 11.0.1.6 (versions before 11.0.1.7).
  2. Confirm the product type
    Determine whether the installation is IBM Controller or IBM Cognos Controller. These are distinct products with different version numbering. Check the product name in the installation or program information.
    Affected if The product is either IBM Controller in the 11.1.0-11.1.1 range or IBM Cognos Controller in the 11.0.0-11.0.1.6 range.
  3. Verify user authentication is enabled
    Check that the application has user authentication configured and active. This vulnerability requires an authenticated user to trigger the improperly validated quantity size input. Verify through the application security settings or user management console.
    Affected if The application allows authenticated users to access features that process quantity size inputs.

You are affected if IBM Controller version is 11.1.0-11.1.1 or IBM Cognos Controller version is 11.0.0-11.0.1.6 and the application accepts authenticated user input for quantity size fields.

Interim mitigation

Implement robust server-side validation for quantity size inputs to ensure values are within acceptable bounds and of the correct data type before processing.

Recommended fix High confidence

IBM Cognos Controller 11.0.1.7 or IBM Controller 11.1.2

  1. 1. Back up the IBM Cognos Controller or Controller database and configuration files
  2. 2. Ensure you have valid IBM Cognos Controller maintenance coverage
  3. 3. Download the appropriate fixed version from IBM Fix Central (11.0.1.7 for Cognos Controller or 11.1.2 for Controller)
  4. 4. Stop all IBM Cognos Controller services
  5. 5. Install the upgrade following IBM's installation documentation
  6. 6. Verify the upgrade by checking the version in About IBM Cognos Controller
  7. 7. Restart the services and test that the application functions normally
