Detailed Explanation for this Vulnerability Assessment

Summary :

The remote web server contains an application server that fails to
protect stored content from modification by remote users.

Description :

According to its banner, the remote web server is Zope < 2.2.5. Such
versions suffer from a security issue involving incorrect protection
of a data updating method on Image and File objects. Because the
method is not correctly protected, it is possible for users with DTML
editing rights to update the raw data of a File or Image object
via DTML though they do not have editing rights on the objects
themselves.

*** Since Nessus solely relied on the version number of your server,
*** consider this a false positive if you applied the hotfix already.

advisory above.
