The JobHistory Server in Cloudera CDH 4.x before 4.6.0 and 5.x before 5.0.0 Beta 2, when using MRv2/YARN with HTTP authentication, allows remote authenticated users to obtain sensitive job information by leveraging failure to enforce job ACLs.

Cloudera Manager 5.5 and earlier allows remote attackers to obtain sensitive information via a (1) stderr.log or (2) stdout.log value in the filename parameter to /cmf/process/<process_id>/logs.

Multiple cross-site scripting (XSS) vulnerabilities in Cloudera HUE 3.9.0 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) First name or (2) Last name field in the HUE Users page.

Cloudera HUE 3.9.0 and earlier allows remote attackers to enumerate user accounts via a request to desktop/api/users/autocomplete.

Multiple cross-site scripting (XSS) vulnerabilities in Cloudera Manager 5.5 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) Template Name field when renaming a template; (2) KDC Server host, (3) Kerberos Security Realm, (4) Kerberos Encryption Types, (5) Advanced Configuration Snippet (Safety Valve) for [libdefaults] section of krb5.conf, (6) Advanced Configuration Snippet (Safety Valve) for the Default Realm in krb5.conf, (7) Advanced Configuration Snippet (Safety Valve) for remaining krb5.conf, or (8) Active Directory Account Prefix fields in the Kerberos wizard; or (9) classicWizard parameter to cmf/cloudera-director/redirect.

Cloudera Manager 5.2.0, 5.2.1, and 5.3.0 stores the LDAP bind password in plaintext in unspecified world-readable files under /etc/hadoop, which allows local users to obtain this password.

Cloudera Manager before 4.8.3 and 5.x before 5.0.1 allows remote authenticated users to obtain sensitive configuration information via the API.

Cloudera Manager 3.7.x before 3.7.5 and Service and Configuration Manager 3.5, when Kerberos is not enabled, does not properly install taskcontroller.cfg, which allows remote authenticated users to impersonate arbitrary user accounts via unspecified vectors, a different vulnerability than CVE-2012-1574.

The Kerberos/MapReduce security functionality in Apache Hadoop 0.20.203.0 through 0.20.205.0, 0.23.x before 0.23.2, and 1.0.x before 1.0.2, as used in Cloudera CDH CDH3u0 through CDH3u2, Cloudera hadoop-0.20-sbin before 0.20.2+923.197, and other products, allows remote authenticated users to impersonate arbitrary cluster user accounts via unspecified vectors.
