GFI HelpDesk < 4.99.9 Stored XSS via charset Parameter
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
GFI HelpDesk before 4.99.9 contains a stored cross-site scripting vulnerability in the language management functionality where the charset POST parameter is passed directly to SWIFT_Language::Create() without HTML sanitization and subsequently rendered unsanitized by View_Language.RenderGrid(). An authenticated administrator can inject arbitrary JavaScript through the charset field when creating or editing a language, and the payload executes in the browser of any administrator viewing the Languages page.
