Plone 2.5 through 2.5.4 and 3.0 through 3.0.2 allows remote attackers to execute arbitrary Python code via network data containing pickled objects for the (1) statusmessages or (2) linkintegrity module, which the module unpickles and executes.

A privilege escalation issue in plone.app.contenttypes in Plone 4.3 through 5.2.1 allows users to PUT (overwrite) some content without needing write permission.

Unspecified vulnerability in the Password Reset Tool before 0.4.1 on Plone 2.5 and 2.5.1 Release Candidate allows attackers to reset the passwords of other users, related to "an erroneous security declaration."

plone.restapi in Plone 5.2.0 through 5.2.1 allows users with a certain privilege level to escalate their privileges up to the highest level.

SQL Injection in DTML or in connection objects in Plone 4.0 through 5.2.1 allows users to perform unwanted SQL queries. (This is a problem in Zope.)

A security flaw (privilege defined with unsafe actions) was found in the way portrait handling component of Plone, a user friendly and powerful content management system, performed portraits management. Remote attacker, authenticated Plone user could use this flaw to modify or delete portraits of other users.

The HTTP PUT and DELETE methods are enabled in the Plone official Docker version 5.2.13 (5221), allowing unauthenticated attackers to execute dangerous actions such as uploading files to the server or deleting them.

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).

Plone 4.0 through 5.1a1 does not have security declarations for Dexterity content-related WebDAV requests, which allows remote attackers to gain webdav access via unspecified vectors.

Missing password strength checks on some forms in Plone 4.3 through 5.2.0 allow users to set weak passwords, leading to easier cracking.

A security flaw was found in the way Plone, a user friendly and powerful content management system, performed certain provided data validation when sending emails. A remote attacker, valid Plone user, could use this flaw to conduct email spoofing attacks.

Cross-site scripting (XSS) vulnerability in the managefindResult component in the search feature in Zope ZMI in Plone before 4.3.12 and 5.x before 5.0.7 allows remote attackers to inject arbitrary web script or HTML via vectors involving double quotes, as demonstrated by the objids:tokens parameter. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-7140.

Plone CMS until version 5.2.4 has a stored Cross-Site Scripting (XSS) vulnerability in the user fullname property and the file upload functionality. The user's input data is not properly encoded when being echoed back to the user. This data can be interpreted as executable code by the browser and allows an attacker to execute JavaScript in the context of the victim's browser if the victim opens a vulnerable page containing an XSS payload.

An open redirect on the login form (and possibly other places) in Plone 4.0 through 5.2.1 allows an attacker to craft a link to a Plone Site that, when followed, and possibly after login, will redirect to an attacker's site.

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.

Unspecified vulnerability in PlonePAS in Plone 2.5 and 2.5.1, when anonymous member registration is enabled, allows an attacker to "masquerade as a group."

A security flaw was found in the way Plone, a user friendly and powerful content management system, enforced immutable setting on certain content edit forms. A remote attacker could use this flaw to provide a specially-crafted URL that would (in a non-persistent way) hide certain fields from these content edit forms, possibly leading to scenario such altered forms to be erroneously accepted by authenticated Plone user as valid.

An XSS issue in the title field in Plone 5.0 through 5.2.1 allows users with a certain privilege level to insert JavaScript that will be executed when other users access the site.

Plone 3.3 through 5.1a1 allows remote attackers to obtain information about the ID of sensitive content via unspecified vectors.

Multiple information exposure flaws were found in the way object manager implementation of Plone, a user friendly and powerful content management system, protected access to its internal methods. A remote attacker could issue a specially-crafted (URL) request that, when processed would lead to information exposure.

Products/CMFPlone/FactoryTool.py in Plone 3.3 through 4.3.2 allows remote attackers to obtain the installation path via vectors related to a file object for unspecified documentation which is initialized in class scope.

Plone 2.0.5, 2.1.2, and 2.5-beta1 does not restrict access to the (1) changeMemberPortrait, (2) deletePersonalPortrait, and (3) testCurrentPassword methods, which allows remote attackers to modify portraits.

A privilege escalation flaw was found in the way Plone, a user friendly and powerful content management system, enforced authorization for users having administrator privilege access for a subtree of a particular node (access to node above that subtree was granted even when the user in question has had administrator privilege only for a subtree of that node). A remote attacker, with administrator user privilege to certain subtree of Plone actions / functionality, could use this flaw to access / alter also higher nodes.

Products/CMFPlone/CatalogTool.py in Plone 3.3 through 4.3.2 allows remote administrators to bypass restrictions and obtain sensitive information via an unspecified search API.

Chameleon (five.pt) in Plone 5.0rc1 through 5.1a1 allows remote authenticated users to bypass Restricted Python by leveraging permissions to create or edit templates.

An information exposure flaw was found in the way zip archives generation functionality of Plone, a user friendly and powerful content management system, enforced user access control privileges on the content to be included into the archive. A remote attacker could use this flaw to obtain sensitive information (by generating a zip archive from content they would not be otherwise able to access).

Multiple cross-site scripting (XSS) flaws were found in the way Plone, a user friendly and powerful content management system, performed sanitization of user provided input in web forms. A remote attacker could provide a specially-crafted URL that, when visited by authenticated Plone user could lead to arbitrary HTML or web script execution in the context of Plone user's session.

An open redirect flaw was found in multiple components of Plone, a user friendly and powerful content management system. Remote attacker could provide a specially-crafted URL that when visited by valid Plone user could lead the Plone user's session to be redirected to external site.

A denial of service flaw was found in the way Plone, a user friendly and powerful content management system, performed particular resource related information retrieval in certain cases (request interaction with internal traversal machinery). A remote attacker, having administrator privilege to certain subset of Plone action screens / functionality, could use this flaw to cause uncontrolled resource consumption (infinite loop) by issuing a specially-crafted request.

Plone 4.x through 4.3.11 and 5.x through 5.0.6 allow remote attackers to bypass a sandbox protection mechanism and obtain sensitive information by leveraging the Python string format method.
