CVE-2020-5026
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 Financial Transaction Manager for Digital Payments for Multi-Platform 3.2.0 through 3.2.7 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: 193662.
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 Financial Transaction Manager for Digital Payments for Multi-Platform versions 3.2.0 through 3.2.7 contains an information disclosure vulnerability where detailed technical error messages (likely stack traces, database details, or system paths) are returned to the browser. A remote attacker can trigger errors and obtain sensitive system information through these verbose error messages, which could aid in further exploitation.

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 version of IBM Financial Transaction ManagerLocate the product version by checking the installation directory or using the IBM version identification utility. Common paths include installation logs or the /opt/ibm/FTM directory. Run 'grep -i version' in installation directories or check the 'version.txt' file if present.Affected if The installed version is 3.2.0.0, 3.2.1, 3.2.2, 3.2.3, 3.2.4, 3.2.5, 3.2.6, or 3.2.7 (any version from 3.2.0.0 through 3.2.7 inclusive).
-
Verify custom error page configurationCheck the IBM WebSphere Application Server or underlying application server configuration files for custom error page mappings. Look for 'error-page' elements in web.xml or the IBM-specific error handling configuration. Verify that detailed errors are mapped to generic pages rather than exposed directly.Affected if No custom error pages are configured, or the configuration explicitly allows stack traces and technical details to be returned to the browser.
-
Test for verbose error message disclosureSend deliberately malformed requests to the application endpoint to trigger error conditions. Examples include invalid input in forms, manipulating request parameters, or accessing non-existent resources. Inspect the HTTP response for stack traces, database connection strings, file paths, or system-specific information.Affected if The application returns detailed technical error messages including stack traces, SQL errors, Java exceptions, or system file paths in the response body.
-
Review error handler logging configurationExamine the application's error handling configuration files and Java code for custom exception handlers. Check if error responses are sanitized before being returned to the client. Look for catch blocks that output exception details directly to the response.Affected if Error handlers or exception handlers are configured to write raw exception details directly to HTTP responses without sanitization.
A user is affected if their IBM Financial Transaction Manager version falls within 3.2.0.0 through 3.2.7 AND the application returns unredacted technical error details (stack traces, database info, or system paths) to browser clients.

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.
dbcve · scopedConfigure custom error pages that return generic, user-friendly messages to the browser while logging detailed technical information server-side only. Review and sanitize all error handlers and exception handlers across the application.
IBM Financial Transaction Manager 3.2.8 or later (or the latest 3.2.x fix pack)
- 1. Identify the current installed version of IBM Financial Transaction Manager for Digital Payments for Multi-Platform by checking the About or version information in the product console.
- 2. If the installed version is between 3.2.0.0 and 3.2.7 (inclusive), plan for an upgrade to a version beyond 3.2.7.
- 3. Contact IBM Support or access the IBM Fix Central portal to obtain the appropriate fix/patch for this vulnerability.
- 4. Review IBM's official security bulletin for CVE-2020-5026 to confirm the specific fixed version or patch number.
- 5. Schedule a maintenance window and perform a full backup of the current FTM system and database.
- 6. Apply the upgrade or install the security patch according to IBM's documentation.
- 7. After upgrading, verify that detailed technical error messages are no longer exposed in the browser by triggering test error conditions.
- 8. Validate that all FTM functionality continues to work correctly after the patch application.
