EPSS Score10.5%

EPSS (Exploit Prediction Scoring System) estimates a 10.5% chance this CVE is exploited in the wild within the next 30 days — higher than 96% of all CVEs. It complements CVSS: a high EPSS on a mid-severity CVE can still be urgent.

Adobe Flash Player contains an incorrect default permissions vulnerability in the Firefox sandbox that allows a remote attacker to execute arbitrary code via crafted SWF content.

Description

The Firefox sandbox in Adobe Flash Player before 10.3.183.67 and 11.x before 11.6.602.171 on Windows and Mac OS X, and before 10.3.183.67 and 11.x before 11.2.202.273 on Linux, does not properly restrict privileges, which makes it easier for remote attackers to execute arbitrary code via crafted SWF content, as exploited in the wild in February 2013.
