It has also has been reported that the cv, jsonRequest, r and ctk parameter could be vulnerable in some instances.

An attacker with access to the Pluck SiteLife software can conduct a cross site scripting attack, which could be used to result in information leakage, privilege escalation, and/or denial of service.

Apply an Update

Pluck has stated that all affected customers have already been notified via email in regards to the new release and changelog documentation is available for customers who login to the Pluck Connect portal. Users are advised to upgrade to release 5.0.13 or later.

Restrict access

As a general good security practice, only allow connections from trusted hosts and networks. Note that restricting access does not prevent XSS or CSRF attacks since the attack comes as an HTTP request from a legitimate user's host. Restricting access would prevent an attacker from accessing a Pluck SiteLife software using stolen credentials from a blocked network location.
