Impact

An unauthenticated attacker could entice a user to browse a specially crafted URL, allowing for the execution of script code in the context of the user's browser and for the theft of browser credentials. This may permit the attacker to login to Webmin or Usermin with the user's permissions.

Workaround

There is no known workaround at this time.

Resolution

All Webmin users should update to the latest stable version:

# emerge --sync
# emerge --ask --verbose --oneshot ">=app-admin/webmin-1.350"
