Description

SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. There is a Cross Site Scripting (XSS) vulnerability in the email viewer in versions 7.14.0 through 7.14.6. An external attacker could send a prepared message to the inbox of the SuiteCRM-instance. By simply viewing emails as the logged-in user, the payload can be triggered. With that, an attacker is able to run arbitrary actions as the logged-in user - like extracting data, or if it is an admin executing the payload, takeover the instance. This is fixed in versions 7.14.7.

Affected products

salesagility SuiteCRM: from 7.14.0 before 7.14.7; from 8.6.0 before 8.8.1 — fixed in 7.14.7, 8.8.1
