Miggo AIRoot Cause Analysis

The vulnerability stems from three key functions:

  1. BaseUrlHelper.getBaseURL() failed to remove matrix parameters from request URLs, allowing them to persist in the base URL.
  2. FormattedServiceListWriter used this contaminated base URL to build absolute endpoint addresses without sanitization, directly embedding user-controlled input in HTML.
  3. ServiceListGeneratorServlet constructed stylesheet links from unsanitized request URIs. The commit diffs show explicit fixes in these areas: matrix parameter stripping in BaseUrlHelper, URL concatenation fixes in FormattedServiceListWriter, and URI sanitization in ServiceListGeneratorServlet - all directly addressing the XSS vector described in CVE-2016-6812.
