New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 3


The remote web server hosts one or multiple .swf files affected by a cross-site scripting vulnerability.


The remote host is hosting one or multiple Flash applets (.swf files) that are using the Flex SDK. Flex is a SDK developed by Adobe that is used to create rich web applications.

The .swf files stored on the remote host have been compiled with an older version of the Flex compiler and may therefore be affected to a cross-site scripting vulnerability.


Either recompile the remote applications with a newer version of the Flex SDK or use the SWF-patching tool Adobe provides.
