GFI HelpDesk before 4.99.9 contains a stored cross-site scripting vulnerability in the template group creation and editing functionality that allows authenticated administrators to inject arbitrary JavaScript by manipulating the companyname POST parameter without HTML sanitization. Attackers can inject malicious scripts through the companyname field that execute in the browsers of any administrator viewing the Templates > Groups page.

GFI HelpDesk before version 4.99.9 allows authenticated administrators to inject stored cross-site scripting (XSS) payloads via the companyname parameter in template group creation and editing, with malicious scripts executing in the browsers of other administrators viewing the Templates > Groups page. The attack requires administrative credentials and user interaction (victim viewing the affected page), but succeeds against all administrator accounts with access to that interface.
