A security flaw was found in the way Plone, a user friendly and powerful content management system, enforced permission checks for user access to subset of attributes of unpublished content items. A remote attacker could provide a specially-crafted URL that, when processed would allow the attacker to determine subset of content metadata about hidden objects by guessing partial values.

The CVE identifier of CVE-2012-5492 has been assigned to this issue: http://www.openwall.com/lists/oss-security/2012/11/10/1
This issue may affect the version of plone as shipped with EPEL5, however the latest version there is 3.1.6 (and the latest 3.x release is 3.3.5, which was released a year prior to this flaw being discovered). Given the age of the EPEL5 package and its lack of support, we do not recommend anyone use it. This issue does not affect plone as provided with the conga package on Red Hat Enterprise Linux 5. Statement: Not vulnerable. This issue did not affect the versions of luci (as provided by conga) as shipped with Red Hat Enterprise Linux 5.
