The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.
CWE-20: Improper Input Validation
flash-player-widget * carries this weakness at mp3, and reaching it takes a caller who can reach the endpoint. Improper input validation means the application accepts input without confirming it has the form, type or range the code downstream assumes.
The concrete impact depends on where the unvalidated value lands, which is why records in this class range from cosmetic bugs to full compromise. No fixed build of this plugin is recorded for flash-player-widget yet, so installs running * stay exposed until the vendor ships one.
