Technical details
A reflected cross-site scripting (XSS) vulnerability exists in Sangoma Switchvox SMB Edition version 8.3 (104997). The vulnerability is located in the invalid_browser and invalid_browser_login handlers, which fail to properly sanitize the 'portal' parameter. User-supplied data from this parameter is reflected into JavaScript generated by the application. An unauthenticated remote attacker can exploit this by inducing a user to visit a malicious URL, leading to the execution of arbitrary script code in the context of the victim's browser session. This can result in session hijacking or unauthorized actions within the web portal. The issue is resolved in version 8.4.0.2.
