CVE-2023-42013
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 · uneditedIBM UrbanCode Deploy (UCD) 7.1 through 7.1.2.14, 7.2 through 7.2.3.7, and 7.3 through 7.3.2.2 could allow a remote attacker to obtain sensitive information when a detailed technical error message is returned in the browser. This information could be used in further attacks against the system. IBM X-Force ID: 265510.
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 · high confidenceIBM UrbanCode Deploy versions 7.1 through 7.1.2.14, 7.2 through 7.2.3.7, and 7.3 through 7.3.2.2 return detailed technical error messages in browser responses that can expose sensitive system configuration, stack traces, or internal path information to remote attackers.

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.
-
Identify installed IBM UrbanCode Deploy versionLocate the version file or check the management console. The version is typically displayed in the IBM UrbanCode Deploy web UI header or in installation logs under the install directory.Affected if The installed version falls within any of these ranges: 7.0.0.0-7.0.5.18, 7.1.0.0-7.1.2.14, 7.2.0.0-7.2.3.7, or 7.3.0.0-7.3.2.2
-
Trigger a test error conditionSend a malformed request to the IBM UrbanCode Deploy web application, such as an invalid URL parameter or request to a non-existent resource, and capture the HTTP response.Affected if The response contains detailed stack traces, Java exception messages, file system paths, or internal configuration values rather than a generic error message
-
Inspect HTTP response headers and body for information disclosureUse a browser developer tool or command-line tool (curl) to examine the full response from an error-generating request. Look for headers like 'X-Stack-Trace' or bodies containing 'java.lang.', 'at com.ibm.', or local file paths.Affected if The response includes Java exception stack traces, class names, or absolute file system paths that reveal internal system details
You are affected if your IBM UrbanCode Deploy version is within 7.0.0.0-7.0.5.18, 7.1.0.0-7.1.2.14, 7.2.0.0-7.2.3.7, or 7.3.0.0-7.3.2.2 AND error responses expose stack traces, internal paths, or system configuration details.
Generated from the published advisory. Verify against your own configuration.
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 to a patched version beyond 7.1.2.14, 7.2.3.7, or 7.3.2.2 as specified by IBM, or configure custom error pages to display generic messages instead of detailed technical information.
