In Apache Ambari versions 2.6.2.2 and earlier, malicious users can construct file names for directory traversal and traverse to other directories to download files.

A cross-site scripting issue was found in Apache Ambari Views. This was addressed in Apache Ambari 2.7.4.

Apache Ambari, versions 1.4.0 to 2.6.1, is susceptible to a directory traversal attack allowing an unauthenticated user to craft an HTTP request which provides read-only access to any file on the filesystem of the host the Ambari Server runs on that is accessible by the user the Ambari Server is running as. Direct network access to the Ambari Server is required to issue this request, and those Ambari Servers that are protected behind a firewall, or in a restricted network zone are at less risk of being affected by this issue.

In Ambari 1.2.0 through 2.2.2, it may be possible to execute arbitrary system commands on the Ambari Server host while generating SSL certificates for hosts in an Ambari cluster.

The File Browser View in Apache Ambari before 2.2.1 allows remote authenticated administrators to read arbitrary files via a file: URL in the WebHDFS URL configuration.

The agent in Apache Ambari before 2.1.2 uses weak permissions for the (1) /var/lib/ambari-agent/data and (2) /var/lib/ambari-agent/keys directories, which allows local users to obtain sensitive information by reading files in the directories.

Apache Ambari before 2.1, as used in IBM Infosphere BigInsights 4.x before 4.1, stores a cleartext BigSheets password in a configuration file, which allows local users to obtain sensitive information by reading this file.

Apache Ambari before 2.1, as used in IBM Infosphere BigInsights 4.x before 4.1, includes cleartext passwords on a Configs screen, which allows physically proximate attackers to obtain sensitive information by reading password fields.

Open redirect vulnerability in Apache Ambari before 2.1.2 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the targetURI parameter.

Cross-site scripting (XSS) vulnerability in Apache Ambari before 2.1.0 allows remote authenticated cluster operator users to inject arbitrary web script or HTML via the note field in a configuration change.

Server-side request forgery (SSRF) vulnerability in the proxy endpoint (api/v1/proxy) in Apache Ambari before 2.1.0 allows remote authenticated users to conduct port scans and access unsecured services via a crafted REST call.
