Plone 4.0.x < 4.3.20 / 5.0.x < 5.1.7 / 5.2.x < 5.2.2 Multiple Vulnerabilities (HF 20200121)

critical Nessus Plugin ID 329011

Synopsis

The remote host is affected by Multiple Vulnerabilities.

Description

The version of Plone installed on the remote host is 4.0.x prior to 4.3.20, 5.0.x prior to 5.1.7, or 5.2.x prior to 5.2.2. It is, therefore, affected by the following vulnerabilities:

 - An open redirect on the login form (and possibly other places) 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.
 (CVE-2020-7936)

 - plone.restapi allows users with a certain privilege level to escalate their privileges up to the highest level. (CVE-2020-7938)

 - SQL Injection in DTML or in connection objects allows users to perform unwanted SQL queries.
 (CVE-2020-7939)

 - 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. (CVE-2020-7940)

 - A privilege escalation issue in plone.app.contenttypes allows users to PUT (overwrite) some content without needing write permission (CVE-2020-7941)

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 (PloneHotfix20200121) may remediate this without a version upgrade, this plugin only reports when running in Paranoid mode.

Solution

Apply the vendor hotfix (Products.PloneHotfix20200121), or upgrade to Plone 4.3.20 / 5.1.7 / 5.2.2 or later.
