The remote web server is a version of Zope which is older than version 2.3.3.

There is a security issue in all releases prior to version 2.3.3.

Any user can visit a ZClass declaration and change the ZClass permission 
mappings for methods and other objects defined within the ZClass, possibly 
allowing for unauthorized access within the Zope instance. 

*** Nessus solely relied on the version number of your server, so if 
*** the hotfix has already been applied, this might be a false positive

Solution : Upgrade to Zope 2.3.3 or apply the hotfix available 
at http://www.zope.org/Products/Zope/Hotfix_2001-05-01/security_alert

Risk factor : Serious";
