CVE-2015-1715: Microsoft Silverlight 5 before 5.1.40416.00 allows remote attackers to bypass intended integrity-level rest...

Security readout for executives and security teams

This is a legacy Microsoft Silverlight issue where a malicious Silverlight application could bypass intended integrity-level restrictions. The main business concern is old endpoints or applications that still depend on Silverlight 5 earlier than 5.1.40416.00. Exposure is most likely on legacy Windows or browser environments where Silverlight 5 remains installed, especially versions earlier than 5.1.40416.00. Modern environments without Silverlight are unlikely to be affected. Treat this as a legacy-technology cleanup and patching item. It is not KEV-listed in the provided bundle, but any remaining Silverlight dependency should be reduced because the platform is obsolete and browser plugin exposure is difficult to defend. Mitigation focus: Identify systems with Microsoft Silverlight installed.; Update Silverlight 5 to version 5.1.40416.00 or later where still required.; Remove Silverlight where no business dependency remains..
