CVE intelligence and bounded remediation

CVE-2017-1500 — Ibm Mobilefirst Platform Foundation security vulnerability

Medium CVSS 6.1

A Reflected Cross Site Scripting (XSS) vulnerability exists in the authorization function exposed by RESTful Web Api of IBM Worklight Framework 6.1, 6.2, 6.3, 7.0, 7.1, and 8.0. The vulnerable parameter is "scope"; if you set as its value a "realm" not defined in authenticationConfig.xml, you get an HTTP 403 Forbidden response and the value will be reflected in the body of the HTTP response. By setting it to arbitrary JavaScript code it is possible to modify the flow of the authorization function, potentially leading to credential disclosure within a trusted session.

Matched remediation archetype

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
