high Nessus Plugin ID 329000
Synopsis
The remote host is affected by multiple vulnerabilities.Description
The version of Plone installed on the remote host is prior to 5.2.3. It is, therefore, affected by the following vulnerabilities:- Plone allows XXE attacks via a feature that is explicitly only available to the Manager role.
(CVE-2020-28734)
- Plone allows SSRF attacks via the tracebacks feature (only available to the Manager role).
(CVE-2020-28735)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to Plone version 5.2.3 or later.See Also
