z3c.form in Plone CMS 5.x through 5.0.6 and 4.x through 4.3.11 allows remote attackers to conduct cross-site scripting (XSS) attacks via a crafted GET request.
Multiple open redirect vulnerabilities in Plone CMS 5.x through 5.0.6, 4.x through 4.3.11, and 3.3.x through 3.3.6 allow remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the referer parameter to (1) %2b%2bgroupdashboard%2b%2bplone.dashboard1%2bgroup/%2b/portlets.Actions or (2) folder/%2b%2bcontextportlets%2b%2bplone.footerportlets/%2b /portlets.Actions or the (3) came_from parameter to /login_form.
Cross-site scripting (XSS) vulnerability in the manage_findResult 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 obj_ids:tokens parameter. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-7140.
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.
