The object manager implementation (objectmanager.py) in Plone 2.1 through 4.1, 4.2.x through 4.2.5, and 4.3.x through 4.3.1 does not properly restrict access to internal methods, which allows remote attackers to obtain sensitive information via a crafted request.

typeswidget.py in Plone 2.1 through 4.1, 4.2.x through 4.2.5, and 4.3.x through 4.3.1 does not properly enforce the immutable setting on unspecified content edit forms, which allows remote attackers to hide fields on the forms via a crafted URL.

The WYSIWYG component (wysiwyg.py) in Plone 2.1 through 4.1, 4.2.x through 4.2.5, and 4.3.x through 4.3.1 allows remote attackers to obtain sensitive information via a crafted URL, which reveals the installation path in an error message.

sendto.py in Plone 2.1 through 4.1, 4.2.x through 4.2.5, and 4.3.x through 4.3.1 allows remote authenticated users to spoof emails via unspecified vectors.

zip.py in Plone 2.1 through 4.1, 4.2.x through 4.2.5, and 4.3.x through 4.3.1 does not properly enforce access restrictions when including content in a zip archive, which allows remote attackers to obtain sensitive information by reading a generated archive.

Multiple unspecified vulnerabilities in (1) dataitems.py, (2) get.py, and (3) traverseName.py in Plone 2.1 through 4.1, 4.2.x through 4.2.5, and 4.3.x through 4.3.1 allow remote authenticated users with administrator access to a subtree to access nodes above the subtree via unknown vectors.

Multiple cross-site scripting (XSS) vulnerabilities in (1) spamProtect.py, (2) pts.py, and (3) request.py in Plone 2.1 through 4.1, 4.2.x through 4.2.5, and 4.3.x through 4.3.1 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.

traverser.py in Plone 2.1 through 4.1, 4.2.x through 4.2.5, and 4.3.x through 4.3.1 allows remote attackers with administrator privileges to cause a denial of service (infinite loop and resource consumption) via unspecified vectors related to "retrieving information for certain resources."

The isURLInPortal method in the URLTool class in in_portal.py in Plone 2.1 through 4.1, 4.2.x through 4.2.5, and 4.3.x through 4.3.1 treats URLs starting with a space as a relative URL, which allows remote attackers to bypass the allow_external_login_sites filtering property, redirect users to arbitrary web sites, and conduct phishing attacks via a space before a URL in the "next" parameter to acl_users/credentials_cookie_auth/require_login.

Plone 4.1.3 and earlier computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters.

Unspecified vulnerability in (1) Zope 2.12.x before 2.12.19 and 2.13.x before 2.13.8, as used in Plone 4.x and other products, and (2) PloneHotfix20110720 for Plone 3.x allows attackers to gain privileges via unspecified vectors, related to a "highly serious vulnerability." NOTE: this vulnerability exists because of an incorrect fix for CVE-2011-0720.

Cross-site scripting (XSS) vulnerability in the safe_html filter in Products.PortalTransforms in Plone 2.1 through 4.1 allows remote authenticated users to inject arbitrary web script or HTML via unspecified vectors, a different vulnerability than CVE-2010-2422.

Cross-site scripting (XSS) vulnerability in Plone 4.1 and earlier allows remote attackers to inject arbitrary web script or HTML via a crafted URL.

Unspecified vulnerability in Plone 2.5 through 4.0, as used in Conga, luci, and possibly other products, allows remote attackers to obtain administrative access, read or create arbitrary content, and change the site skin via unknown vectors.

Cross-site scripting (XSS) vulnerability in PortalTransforms in Plone 2.1 through 3.3.4 before hotfix 20100612 allows remote attackers to inject arbitrary web script or HTML via the safe_html transform.

The PlonePAS product 3.x before 3.9 and 3.2.x before 3.2.2, a product for Plone, does not properly handle the login form, which allows remote authenticated users to acquire the identity of an arbitrary user via unspecified vectors.
