An issue was discovered in Cloudera Manager before 5.13.4, 5.14.x before 5.14.4, and 5.15.x before 5.15.1. A read-only user can access sensitive cluster information.

An issue was discovered in Cloudera Data Science Workbench (CDSW) 1.4.0 through 1.4.2. Authenticated users can bypass project permission checks and gain read-write access to any project folder.

Cloudera CDH has Insecure Permissions because ALL cannot be revoked.This affects 5.x through 5.15.1 and 6.x through 6.0.1.

Open redirect vulnerability in Cloudera HUE before 3.10.0 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the next parameter.

An issue was discovered in Cloudera Data Science Workbench (CDSW) 1.x before 1.2.0. Several web application vulnerabilities allow malicious authenticated users of CDSW to escalate privileges in CDSW. CDSW users can exploit these vulnerabilities in combination to gain root access to CDSW nodes, gain access to the CDSW database which includes Kerberos keytabs of CDSW users and bcrypt hashed passwords, and gain access to other privileged information such as session tokens, invitation tokens, and environment variables.

Impala in CDH 5.2.0 through 5.7.2 and 5.8.0 allows remote attackers to bypass Setry authorization.

Apache Hadoop 0.23.x before 0.23.11 and 2.x before 2.4.1, as used in Cloudera CDH 5.0.x before 5.0.2, do not check authorization for the (1) refreshNamenodes, (2) deleteBlockPool, and (3) shutdownDatanode HDFS admin commands, which allows remote authenticated users to cause a denial of service (DataNodes shutdown) or perform unnecessary operations by issuing a command.

Cloudera Navigator 2.2.x before 2.2.4 and 2.3.x before 2.3.3 include support for SSLv3 when configured to use SSL/TLS, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, a variant of CVE-2014-3566 (aka POODLE).

Cloudera Key Trustee Server before 5.4.3 does not store keys synchronously, which might allow attackers to have unspecified impact via vectors related to loss of an encryption key.

Cloudera Manager 4.x, 5.0.x before 5.0.6, 5.1.x before 5.1.5, 5.2.x before 5.2.5, and 5.3.x before 5.3.3 uses global read permissions for files in its configuration directory when starting YARN NodeManager, which allows local users to obtain sensitive information by reading the files, as demonstrated by yarn.keytab or ssl-server.xml in /var/run/cloudera-scm-agent/process.
