CVE-2012-5499

python_scripts.py en Plone anterior a 4.2.3 y 4.3 anterior a beta 1 permite a atacantes remotos causar una denegación de servicio (consumo de memoria) a través de un valor grande, relacionado con formatColumns.

It was discovered that Plone, included as a part of luci, did not properly handle the processing of very large values passed to an internal utility function. A remote attacker could use a specially crafted URL that, when processed, would lead to excessive memory consumption.

The Conga project is a management system for remote workstations. It consists of luci, which is a secure web-based front end, and ricci, which is a secure daemon that dispatches incoming messages to underlying management modules. It was discovered that Plone, included as a part of luci, did not properly protect the administrator interface. A remote attacker could use this flaw to inject a specially crafted Python statement or script into Plone's restricted Python sandbox that, when the administrator interface was accessed, would be executed with the privileges of that administrator user.
