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).

Security readout for executives and security teams

Older Zope deployments, including affected Plone releases, used predictable random behavior because the PRNG was not reseeded. That can make security-sensitive random values easier to guess. Public sources do not specify the exact guessed value or business workflow affected. Exposure is most likely in legacy Zope 2 or Plone 4.2.x and pre-4.3-beta environments that missed the 2012 Plone/Zope updates or hotfix. Treat this as a legacy-platform hygiene issue unless inventory shows exposed, unpatched Plone/Zope systems. The priority rises for public sites or systems relying on unpredictable values for session, workflow, or authorization behavior. Mitigation focus: Upgrade Zope to 2.13.19 or later where applicable.; Upgrade Plone to 4.2.3 or a fixed 4.3 release path.; Apply the referenced Plone 20121124 hotfix if upgrade is delayed..
