2FA VPN Authorization email link is vulnerable to XSS injection
Options
Freshman Member
Hello,
We have recently enabled 2 Factor Authentication for VPN Access on a Zywall 110. We noticed that the Authentication link is vulnerable to XSS injection, as displayed below:
https://Address/2FA-access.cgi?key=%22;%20alert(1)//
We removed the Address, but this is the link that is sent via email. We have modified the key to show a proof of concept.
Will there be a fix for this in future firmware updates?
We look forward to your reply.
