Vulnerability Title
Kiteworks Core Stored Cross-site Scripting (XSS)
Source: CVE Program / CVE List V5
Vulnerability Description
A stored cross-site scripting (XSS) weakness in Kiteworks Core could allow an administrator holding only a single, narrowly scoped delegated permission to store crafted content that later executes arbitrary JavaScript in the authenticated session of a System Administrator who views the affected page. This could have permitted the lower-privileged administrator to escalate to full administrative control of the tenant, including the creation of a new administrative account.
