Adobe Acrobat Pro XI must be configured to block Flash Content.


Overview

Finding ID Version Rule ID IA Controls Severity
V-75273 ADBP-XI-000290 SV-89953r1_rule Medium
Description
Flash has a long history of vulnerabilities. Although Flash is no longer provided with Acrobat, if the system has Flash installed, a malicious PDF could execute code on the system. Configuring Flash to run from a privileged location limits the execution capability of untrusted Flash content that may be embedded in the PDF.
