Описание
A flaw was found in pfSense Plus and CE. An authenticated user with the 'Firewall: Schedules: Edit' privilege can inject malicious JavaScript code into the schedule description. This code is stored without proper sanitization and executes in the browser of any user with the 'Firewall: Rules' privilege when they view the firewall rules list. This vulnerability, known as stored Cross-Site Scripting (XSS), allows for arbitrary code execution, potentially leading to information disclosure or other client-side attacks.

pfSense Plus before 26.07 and CE before 2.9.0 allow authenticated users with the Firewall: Schedules: Edit privilege to inject arbitrary JavaScript via the descr parameter in /firewall_schedule_edit.php. The schedule description is stored without HTML sanitization and subsequently inserted into an HTML attribute value in /firewall_rules.php with only single-quote escaping applied, permitting double-quote breakout. The payload executes in the browser of any user with the Firewall: Rules privilege who views the rules list with the affected schedule attached.
