CVE-2012-5504 conga (Plone): Persistent XSS
Last modified: 2016-03-04 06:29:19 EST
A persistent / stored cross-site scripting (XSS) flaw was found in the way Plone, a user friendly and powerful content management system based on Zope, performed sanitization of certain URL parameters. A remote attacker could provide a specially-crafted URL that, when processed, would store the unsanitized string content as a value of key in memory, resulting into situation where subsequent attempt to load that URL would lead to arbitrary HTML or web script execution.

The CVE identifier of CVE-2012-5504 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.
