python_scripts.py in Plone before 4.2.3 and 4.3 before beta 1 allows remote attackers to execute Python code via a crafted URL, related to createObject.

atat.py in Plone before 4.2.3 and 4.3 before beta 1 allows remote attackers to read private data structures via a request for a view without a name.

z3c.form, as used in Plone before 4.2.3 and 4.3 before beta 1, allows remote attackers to obtain the default form field values by leveraging knowledge of the form location and the element id.

queryCatalog.py in Plone before 4.2.3 and 4.3 before beta 1 allows remote attackers to bypass caching and cause a denial of service via a crafted request to a collection.

uid_catalog.py in Plone before 4.2.3 and 4.3 before beta 1 allows remote attackers to obtain metadata about hidden objects via a crafted URL.

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."

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.

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.

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.

Multiple open redirect vulnerabilities in (1) marmoset_patch.py, (2) publish.py, and (3) principiaredirect.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 redirect users to arbitrary web sites and conduct phishing attacks via unspecified vectors.
