CVE-2018-1639
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.

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 confidenceThe Report Builder component in IBM Jazz Reporting Service versions 5.0 through 5.0.2 and 6.0 through 6.0.6 contains an information disclosure vulnerability allowing authenticated users to access sensitive data beyond their assigned privileges. This is an authorization bypass in the reporting functionality where proper access controls are not enforced on report data visibility.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm IBM Jazz Reporting Service installationCheck for Jazz Reporting Service installation directory, running process, or application server hosting the service. Typical paths include <install_dir>/jrs or check for the jrs.ear file in the application deployment directory.Affected if Jazz Reporting Service is not installed - then not affected
-
Identify installed Jazz Reporting Service versionLocate the version file or check the product information. Typically found in <install_dir>/jrs/_versionInfo or through the Jazz application server admin console. Compare the version number to the affected ranges: 5.0 through 5.0.2, 6.0 through 6.0.2, or 6.0.3 through 6.0.6.Affected if Installed version falls within any of these ranges: 5.0-5.0.2, 6.0-6.0.2, or 6.0.3-6.0.6
-
Verify Report Builder component is configuredCheck if the Report Builder feature is enabled in Jazz Reporting Service. This can be verified through the Jazz admin interface under the reporting services configuration, or by checking for Report Builder artifacts in the installation.Affected if Report Builder is not configured or not in use - then likely not affected by this specific vulnerability in that component
-
Inspect report access control configurationsReview the report visibility and data access permissions configured in Report Builder. Check whether users can potentially access report data beyond their assigned project/team permissions through the reporting interface.Affected if Users with limited permissions can access report data outside their assigned scope, indicating the authorization bypass is present
User is affected if Jazz Reporting Service version is 5.0-5.0.2, 6.0-6.0.2, or 6.0.3-6.0.6 AND the Report Builder component is enabled and in use.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade Jazz Reporting Service to version 5.0.3 or 6.0.7 or later per IBM's security bulletin to remediate the improper privilege enforcement in Report Builder.
