This vulnerability has a CVSS 3.0 base score of 4.4, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
Sails is an MVC style framework for building realtime web applications. Version 0.12.7 and lower have an issue with the CORS configuration where the value of the origin header is reflected as the value for the Access-Control-Allow-Origin header. This would allow an attacker to make AJAX requests to vulnerable hosts through cross site scripting or a malicious HTML Document, effectively bypassing the Same Origin Policy. Note that this is only an issue when `allRoutes` is set to `true` and `origin` is set to `*` or left commented out in the sails CORS config file. The problem can be compounded when the cors `credentials` setting is not provided. At that point authenticated cross domain requests are possible.
Remediation
Check the references section for vendor advisories and patches from sailsjs. Update sails to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
