Overview
Cross-site scripting (XSS) vulnerability in admin.asp page.
Affected Products/Versions
Mutare Voice (EVM), 3.0.0-3.3.7
Vulnerability Details
On the admin portal of the Mutare Voice (EVM) web application, the admin.asp page has an XSS vulnerability. One can add a User on /admin.asp with Full Name “><video><source onerror=eval(alert(1))>. This can be used to steal any user’s session since session cookies are not set with the HTTP only flag.
Workarounds
Affected pages are admin-facing and could be removed from user-facing implementations until the system could be patched.
Solution
Upgrading Mutare Voice (EVM) to release 3.3.8 fixes the vulnerability by obfuscating the external password values via the web portal.
