Originally, Common Vulnerabilities and Exposures assigned an identifier CVE-2010-1104 to the following vulnerability:

If a remote attacker could trick a user, who was logged into Zope3, into examining error entries for particular Zope3 instance, it would lead to arbitrary web script execution in the context of user's Zope3 session.
