CVE-2009-3956: The default configuration of Adobe Reader and Acrobat 9.x before 9.3, and 8.x before 8.2 on Windows and Mac...

The default configuration of Adobe Reader and Acrobat 9.x before 9.3, and 8.x before 8.2 on Windows and Mac OS X, does not enable the Enhanced Security feature, which has unspecified impact and attack vectors, related to a "script injection vulnerability," as demonstrated by Acrobat Forms Data Format (FDF) behavior that allows cross-site scripting (XSS) by user-assisted remote attackers.

Security readout for executives and security teams

This issue affects older Adobe Reader and Acrobat installations where Enhanced Security was not enabled by default. A user-assisted attack involving Acrobat Forms Data Format behavior could lead to script injection or XSS. The sources do not provide CVSS severity or detailed impact, so urgency depends on whether legacy Adobe clients remain in use. Exposure is most likely in legacy desktop fleets still running Adobe Reader or Acrobat 8.x or 9.x before the fixed releases. Modern, updated Adobe clients should not be assumed affected from this bundle alone. Prioritize this as a legacy software exposure review, not a confirmed active-crisis item. If affected Adobe clients remain, remove or update them quickly because user-assisted document attacks are common enterprise entry points. Mitigation focus: Upgrade Adobe Reader and Acrobat to 9.3, 8.2, or later fixed versions.; Enable Adobe Enhanced Security where legacy clients cannot be immediately removed.; Retire unsupported Adobe Reader and Acrobat versions from managed endpoints..
