CVE-2014-9678
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedFlexPaperViewer.swf in Flexpaper before 2.3.1 allows remote attackers to conduct content-spoofing attacks via the Swfile parameter.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceFlexPaperViewer.swf in Flexpaper before 2.3.1 contains a content-spoofing vulnerability where the Swfile parameter can be manipulated by remote attackers to cause the viewer to display arbitrary content, tricking users into believing they are viewing legitimate documents.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate FlexPaperViewer.swf fileSearch web server document roots and application directories for files named 'FlexPaperViewer.swf' using file system searches (e.g., find /var/www -name 'FlexPaperViewer.swf' or Windows equivalent).Affected if The file exists in the environment and its version is 2.3.0 or earlier.
-
Determine FlexPaperViewer.swf versionCheck the file properties or metadata of FlexPaperViewer.swf. Alternatively, check the Flexpaper version reported in the application or any version.txt/readme files in the same directory. Compare against the affected version range (2.3.0 and below).Affected if The installed version is Flexpaper <= 2.3.0.
-
Verify Swfile parameter acceptanceIntercept or examine HTTP requests sent to the Flexpaper viewer endpoint. Observe whether the 'Swfile' parameter (or 'swfile') can be controlled via URL query string or POST data to point to external or arbitrary file locations.Affected if The application accepts and processes a user-controlled Swfile parameter without validation.
-
Confirm content rendering behaviorTest the endpoint by supplying a crafted Swfile parameter pointing to a non-document file or external URL. Observe whether the viewer attempts to render or display the provided content as if it were a valid document.Affected if The viewer displays arbitrary content supplied via the Swfile parameter, indicating the vulnerability is present.
A user is affected if Flexpaper version 2.3.0 or earlier is installed and the FlexPaperViewer.swf component processes the Swfile parameter without proper validation, allowing content-spoofing attacks.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade Flexpaper to version 2.3.1 or later to obtain the patched version of FlexPaperViewer.swf that properly validates the Swfile parameter.
