Anchor CVE-2017-5642 CVE-2017-5642
CVE-2017-5642: Ambari Server artifacts do not have proper ACLs
Severity: Important
Vendor: The Apache Software Foundation
Versions Affected: 2.4.0 to 2.4.2
Versions Fixed: 2.4.3, 2.5.0
Description: During installation, Ambari Server artifacts are not created with proper ACLs
Mitigation: Ambari users should upgrade to version 2.5.0 or above. For users of Version 2.4.0 through Version 2.4.2, either upgrade to version 2.4.3 or execute the script provided with Version 2.5.0 to correct the ACLs on Ambari server artifacts.
The proper ACL's are set for installed Ambari artifacts in Ambari versions 2.4.3, 2.5.0 and later. However, users of Version 2.4.0 through 2.4.2 may execute the script found at https://github.com/apache/ambari/blob/release-2.5.0/ambari-server/src/main/resources/scripts/check_ambari_permissions.py to fix the permissions on Ambari server artifacts on the Ambari server host.

...
Anchor CVE-2017-5655 CVE-2017-5655
...
Mitigation: Ambari users should upgrade to version 2.4.0 or above.
Version 2.4.0 onwards properly enforces that agent-supplied host names are valid hostnames before attempting to execute OpenSSL commands to create SSL certificates. However, this feature may be disabled by setting security.agent.hostname.validate to "false" in the ambari.properties file. It is strongly recommended that the default value of security.agent.hostname.validate is not changed since it may enable this vulnerability.

Anchor CVE-2015-3186 CVE-2015-3186
CVE-2015-3186: Apache Ambari XSS vulnerability
Severity: Important
Vendor: The Apache Software Foundation
Versions Affected: 1.7.0 to 2.0.2
Versions Fixed: 2.1.0
Description: Ambari allows authenticated cluster operator users to specify arbitrary text as a note when saving configuration changes. This note field is rendered as is (unescaped HTML). This exposes opportunities for XSS.
Mitigation: Ambari users should upgrade to version 2.1.0 or above.
Version 2.1.0 onwards properly HTML-escapes the note field associated with configuration changes.
