Netgate · Pfsense · CVE-2020-11457
**Name of the Vulnerable Software and Affected Versions**
pfSense versions prior to 2.4.5
**Description**
The issue concerns stored XSS in the WebGUI, specifically in the system usermanager addprivs.php file, via the `descr` parameter, also known as the full name of a user.
**Recommendations**
For versions prior to 2.4.5, update to version 2.4.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the system usermanager addprivs.php file in the WebGUI to minimize the risk of exploitation. Avoid using the `descr` parameter in the affected WebGUI until the issue is resolved.
