CyberRota Analysis
AI-GeneratedAuthenticated users with the Firewall: Rules: Edit privilege in pfSense Plus versions prior to 26.07 and CE versions before 2.9.0 can inject arbitrary JavaScript through the descr parameter in the firewall rules editing interface. This vulnerability allows the injected script to execute in the browsers of users with the Status: Logs: Firewall privilege who access the affected log entries, potentially leading to cross-site scripting (XSS) attacks. Organizations using these pfSense versions should prioritize remediation to protect against potential exploitation by malicious actors.
Original NVD Description
pfSense Plus before 26.07 and CE before 2.9.0 allow authenticated users with the Firewall: Rules: Edit privilege to inject arbitrary JavaScript via the descr parameter in /firewall_rules_edit.php. The firewall rule description is stored in the pfSense XML configuration with only backslash-escaping applied and no HTML sanitization, then rendered without encoding in the firewall log table in /status_logs_filter.php. The payload executes in the browser of any user with the Status: Logs: Firewall privilege who views the affected log entries.
