Authenticated browser script execution via unescaped report dates
Published Oct 30, 2025 · Updated Oct 30, 2025
Cross-site scripting in Nagios XI before 5.2.4 allows remote authenticated users to execute script in a victim's browser through Reports fields. The Reports interface inserts attacker-controlled startdate and enddate values into generated page content without sufficient validation or context-appropriate escaping. A victim must open the affected report view; the injected script runs with that user's browser privileges and can read or alter data exposed to the page.
