CVE-2018-1430
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 API Connect 5.0.0.0 through 5.0.8.2 is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM X-Force ID: 139226.
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 confidenceIBM API Connect 5.0.0.0 through 5.0.8.2 contains a stored cross-site scripting (XSS) vulnerability in its Web UI. Attackers can embed malicious JavaScript code into the interface that executes in the browsers of other users viewing the same content, potentially allowing session hijacking and credentials disclosure within trusted sessions.

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 API Connect versionRun 'apic --version' or check the product information in the API Connect Admin UI under Settings > Version. Alternatively, check the installation directory for version manifest files.Affected if The displayed version falls within the range 5.0.0.0 through 5.0.8.2 (inclusive).
-
Verify Web UI component is enabledCheck the API Connect configuration for the portal or Web UI component status. Look for the 'apim-ui' or 'portal' service configuration in the deployment topology or by accessing the management API endpoint /platform-api.Affected if The Web UI service is active and accessible to users.
-
Confirm network exposure of Web UIDetermine if the Web UI is reachable from the network by reviewing firewall rules, load balancer configurations, or API Connect ingress definitions. Verify the listening ports (typically 9443 or 443 for HTTPS).Affected if The Web UI is externally accessible or accessible to users beyond the administrative localhost scope.
You are affected if your IBM API Connect installation runs version 5.0.0.0 through 5.0.8.2 and the Web UI component is enabled and accessible to users.
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 IBM API Connect to a version beyond 5.0.8.2 that contains the security fix. Additionally, implement robust input validation and output encoding across all user-supplied content in the Web UI, and consider deploying Content Security Policy headers to mitigate XSS risks.
