CVE-2018-5431
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 · uneditedThe domain designer component of TIBCO Software Inc.'s TIBCO JasperReports Server, TIBCO JasperReports Server Community Edition, TIBCO JasperReports Server for ActiveMatrix BPM, TIBCO Jaspersoft for AWS with Multi-Tenancy, and TIBCO Jaspersoft Reporting and Analytics for AWS contains a vulnerability which may allow, in the context of a non-default permissions configuration, persisted cross-site scripting (XSS) attacks. Affected releases include TIBCO Software Inc.'s TIBCO JasperReports Server: versions up to and including 6.2.4; 6.3.0; 6.3.2; 6.3.3; 6.4.0; 6.4.2, TIBCO JasperReports Server Community Edition: versions up to and including 6.4.2, TIBCO JasperReports Server for ActiveMatrix BPM: versions up to and including 6.4.2, TIBCO Jaspersoft for AWS with Multi-Tenancy: versions up to and including 6.4.2, TIBCO Jaspersoft Reporting and Analytics for AWS: versions up to and including 6.4.2.
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 confidenceA stored cross-site scripting (XSS) vulnerability exists in the domain designer component of TIBCO JasperReports Server and related products. The vulnerability can be exploited in non-default permission configurations, allowing attackers to inject malicious scripts that persist within the system.

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 JasperReports Server versionAccess the server admin interface or check the product about page. Typically found in: Manage > Server Settings > About, or by inspecting the jasperreports-server-build.properties file in the installation directory.Affected if The installed version matches <= 6.2.4, 6.3.0, 6.3.2, 6.3.3, 6.4.0, 6.4.2, or any version <= 6.4.2.
-
Confirm Jaspersoft product variantIdentify whether the installation is JasperReports Server, Jaspersoft, or Jaspersoft Reporting And Analytics. Check the product name displayed in the admin UI or installation metadata.Affected if The product is any of the three listed affected products and the version is <= 6.4.2.
-
Verify domain designer component is accessibleCheck if the Domain Designer feature is enabled and accessible within the installation. This is typically found under: Create > Domain, or in the Ad Hoc Views section where users can design domains.Affected if The domain designer component is present and accessible to users.
-
Inspect domain designer permission configurationsReview the permission settings for domain designer. Navigate to: Manage > Roles and Permissions, or the domain security settings. Look for any non-default permission grants to standard or non-standard users.Affected if Non-default permissions have been configured for the domain designer, granting elevated or unusual access to users who would not have it by default.
-
Search for suspicious stored content in domainsReview any custom domains created via domain designer. Check the domain schema, calculated fields, and display names for any unexpected script tags, javascript: URIs, or HTML elements that may indicate injected XSS payloads.Affected if Any stored XSS payloads are found within domain definitions, particularly in field names, descriptions, or calculated expressions.
A user is affected if they are running any of the listed product versions (JasperReports Server <= 6.4.2, Jaspersoft <= 6.4.2, or Jaspersoft Reporting And Analytics <= 6.4.2) AND the domain designer component is accessible with non-default permissions configured.

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 dataApply vendor patches when available; until then, restrict domain designer permissions to minimize attack surface and implement strict input validation on all user-supplied content.
