  - membership_tool.py in Plone allows remote attackers to enumerate user account names via a crafted URL.
    (CVE-2012-5497)

  - python_scripts.py in Plone allows remote attackers to cause a denial of service (memory consumption) via a     large value, related to formatColumns. (CVE-2012-5499)

  - The batch id change script (renameObjectsByPaths.py) in Plone allows remote attackers to change the titles     of content items by leveraging a valid CSRF token in a crafted request. (CVE-2012-5500)

  - at_download.py in Plone allows remote attackers to read arbitrary BLOBs (Files and Images) stored on custom     content types via a crafted URL. (CVE-2012-5501)

  - Cross-site scripting (XSS) vulnerability in safe_html.py in Plone allows remote authenticated users with     permissions to edit content to inject arbitrary web script or HTML via unspecified vectors.
    (CVE-2012-5502)

  - ftp.py in Plone allows remote attackers to read hidden folder contents via unspecified vectors.
    (CVE-2012-5503)

  - Cross-site scripting (XSS) vulnerability in widget_traversal.py in Plone allows remote attackers to inject     arbitrary web script or HTML via unspecified vectors. (CVE-2012-5504)

  - atat.py in Plone allows remote attackers to read private data structures via a request for a view without     a name. (CVE-2012-5505)

  - python_scripts.py in Plone allows remote attackers to cause a denial of service (infinite loop) via an RSS     feed request for a folder the user does not have permission to access. (CVE-2012-5506)

  - AccessControl/AuthEncoding.py in Zope, as used in Plone, allows remote attackers to obtain passwords via     vectors involving timing discrepancies in password validation. (CVE-2012-5507)

  - The error pages in Plone allow remote attackers to obtain random numbers and derive the PRNG state for     password resets via unspecified vectors. (CVE-2012-5508)

  - Zope, as used in Plone, does not reseed the pseudo-random number generator (PRNG), which makes it easier     for remote attackers to guess the value via unspecified vectors. (CVE-2012-6661)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number. Since a vendor hotfix (PloneHotfix20121106) may remediate this without a version upgrade, this plugin only reports when running in Paranoid mode.
