Details

PostfixAdmin through 4.0.5 contains a stored cross-site scripting vulnerability that allows authenticated mailbox users to inject script by creating a TOTP exception with an unescaped description. When a global administrator views totp-exceptions.php, the script runs in the admin session and can issue authenticated admin requests using the page's CSRF token.
