I am getting this error when trying to submit a CA Service Catalog request via USS. It appears in the Console on the browser.
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://<SC CATALOG>:8080/usm/wpf?Node=icguinode.submitservicerequest&b2b=json&sh=8vfbPnJkPcu3L8ITJMoPcOeV%2BCs%3D&portal=true&locale=en_US. (Reason: CORS header 'Access-Control-Allow-Origin' missing).
Does this error appears when using other browsers such as Chrome or Firefox?
This is what I get the the IE that is part of Windows 10.
SEC7120: Origin http://causs01 not found in Access-Control-Allow-Origin header.

Do you have any specific patches on Catalog/USS for this? I believe this was addressed on Catalog as a fix/cumulative patch with some post install instructions to enable cross origin headers.
If 14.1.02 (CP2) has been applied you can enable the CORS filter as per the following:
Post Installation Steps for CA Service Catalog - CA Service Management - 14.1 - CA Technologies Documentation
Regardless of having CP2 installed or not you can enable the required CORS filter in Tomcat by following this guide: http://stackoverflow.com/questions/16296145/set-cors-header-in-tomcat/18850438#18850438 Of course with CP2 you might be better off with doing it with the post-install steps.
Be aware that Firefox will get a hiccup with wildcard domains so using the domain-specific configuration mentioned in the post-install steps instead of the wildcard is preferred. Also, if your Tomcat is older than 7.0.41 you need to download an additional JAR file to have the CORS filter class available for Tomcat. These are all mentioned on the link but I thought to emphasize the things I struggled with
