CVE-2012-5508 CVE-2012-6661 conga (Plone): Python random generator used instead of system random generator
Last modified: 2014-11-05 09:45:46 EST
It was reported that Plone, a user friendly and powerful content management system based on Zope, used Python language based pseudo-random number generator (PRNG) instead of a system one for generation of pseudo-random numbers. Also, previously, certain Plone error pages leaked random numbers, making it possible for a remote attacker to derive the state of the PRNG in the moment of password reset requests.

From OSS post: [4] http://www.openwall.com/lists/oss-security/2012/11/07/4 relevant HotFix patch is random_string.py change.
The CVE identifier of CVE-2012-5508 has been assigned to this issue: http://www.openwall.com/lists/oss-security/2012/11/10/1
Reference: https://bugs.launchpad.net/zope2/+bug/1071067
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.
A CVE split has occurred: Common Vulnerabilities and Exposures assigned an identifier CVE-2012-6661 to the following vulnerability: Name: CVE-2012-6661 URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-6661 Assigned: 20141103 Reference: http://www.openwall.com/lists/oss-security/2012/11/10/1 Reference: https://bugs.launchpad.net/zope2/+bug/1071067 Reference: https://github.com/plone/Products.CMFPlone/blob/4.2.3/docs/CHANGES.txt Reference: https://plone.org/products/plone-hotfix/releases/20121124 Reference: https://plone.org/products/plone/security/advisories/20121106/24 Zope before 2.13.19, as used in Plone before 4.2.3 and 4.3 before beta 1, does not reseed the pseudo-random number generator (PRNG), which makes it easier for remote attackers to guess the value via unspecified vectors. NOTE: this issue was SPLIT from CVE-2012-5508 due to different vulnerability types (ADT2).
