An unauthenticated reflected cross-site scripting (XSS) vulnerability exists in Sangoma Switchvox SMB Edition version 8.3 (104997). The application fails to properly sanitize the portal parameter supplied to the invalid_browser and invalid_browser_login handlers. User-supplied data is reflected into JavaScript generated by the application, allowing attacker-controlled script execution within a victim's browser.
