Title
Reflected Cross-Site Scripting in Dashboard Search
Summary
A reflected cross-site scripting (XSS) vulnerability in the dashboard search functionality of the VertiGIS FM solution allows attackers to craft a malicious URL, that if visited by an authenticated victim, will execute arbitrary JavaScript in the victim's context. Such a URL could be delivered through various means, for instance, by sending a link or by tricking victims to visit a page crafted by the attacker.
