CVE-2020-4277
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 TRIRIGA Application Platform 3.5.3 and 3.6.1 discloses sensitive information in error messages that could aid an attacker formulate future attacks. IBM X-Force ID: 175993.
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 TRIRIGA Application Platform versions 3.5.3 and 3.6.1 expose sensitive information in error messages. This information disclosure vulnerability could reveal system details, stack traces, or configuration specifics that assist attackers in reconnaissance and formulating targeted follow-on attacks.

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.
-
Verify the installed IBM TRIRIGA versionAccess the IBM TRIRIGA administration console or check the application metadata (typically found in the About section, version.properties file, or system information page within the platform).Affected if The installed version is exactly 3.5.3 or exactly 3.6.1.0.
-
Identify error handling configurationLocate the IBM TRIRIGA error handling and logging configuration files (commonly in the WEB-INF directory or configuration folder). Check the custom error page settings and error message templates.Affected if Default error handlers are in use and no custom error pages have been configured to sanitize output.
-
Trigger a test error conditionSubmit invalid input to common IBM TRIRIGA forms or endpoints (such as login, search, or data submission pages) to generate an error response. Alternatively, access a non-existent page or resource within the application.Affected if The returned error page displays system details, Java stack traces, file paths, database connection strings, or configuration values.
-
Inspect HTTP response headersUse browser developer tools or a command-line tool (curl -i) to capture HTTP response headers from error-generating requests.Affected if Headers reveal server version numbers, internal IP addresses, or technology stack details (such as Java version or application server information).
You are affected if your installed IBM TRIRIGA version is 3.5.3 or 3.6.1.0 and error responses expose stack traces, system paths, configuration details, or other sensitive reconnaissance information.

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 dataImplement custom error handlers that return generic error messages to users while logging detailed error information server-side for debugging. Review and sanitize all error output across the platform.
