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 Cloud App Management 2019.3.0 and 2019.4.0 reveals a stack trace on certain API requests which can allow an attacker further information about the implementation of the offering. IBM X-Force ID: 173311.

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 Cloud App Management versions 2019.3.0 and 2019.4.0 contains an information disclosure vulnerability where certain API requests return stack traces in error responses, exposing implementation details about the application to attackers.

MitigationUpgrade to a patched version of IBM Cloud App Management and ensure custom error handling is implemented to prevent stack traces from being returned in API responses.

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 IBM Cloud App Management version
    Locate the version information through the product administration interface, configuration files, or installation metadata. Common methods include checking the About section in the product UI or examining version files in the installation directory.
    Affected if The installed version is exactly 2019.3.0 or exactly 2019.4.0
  2. Trigger an API error condition
    Send a malformed or invalid request to any API endpoint of IBM Cloud App Management. This can include requests with missing required parameters, invalid authentication tokens, or requests to non-existent resources.
    Affected if The API returns an error response containing Java stack traces, exception class names, or detailed implementation paths in the response body

A user is affected if their IBM Cloud App Management installation is version 2019.3.0 or 2019.4.0 AND API error responses expose stack traces or implementation details.

Generated from the published advisory. Verify against your own configuration.
