CF CLI version prior to v6.45.0 (bosh release version 1.16.0) writes the client id and secret to its config file when the user authenticates with --client-credentials flag. A local authenticated malicious user with access to the CF CLI config file can act as that client, who is the owner of the leaked credentials.

Splunk-SDK-Python before 1.6.6 does not properly verify untrusted TLS server certificates, which could result in man-in-the-middle attacks.

Splunkd in Splunk Enterprise 6.2.x before 6.2.14 6.3.x before 6.3.11, and 6.4.x before 6.4.8; and Splunk Light before 6.5.0 allow remote attackers to cause a denial of service via a malformed HTTP request.

Directory traversal vulnerability in the Splunk Django App in Splunk Enterprise 6.0.x before 6.0.14, 6.1.x before 6.1.13, 6.2.x before 6.2.14, 6.3.x before 6.3.10, 6.4.x before 6.4.6, and 6.5.x before 6.5.3; and Splunk Light before 6.6.0 allows remote authenticated users to read arbitrary files via unspecified vectors.

Splunk Enterprise 6.2.x before 6.2.14, 6.3.x before 6.3.10, 6.4.x before 6.4.7, and 6.5.x before 6.5.3; and Splunk Light before 6.6.0 allow remote attackers to cause a denial of service via a crafted HTTP request.

Cross-site scripting (XSS) vulnerability in Splunk Web in Splunk Enterprise 6.0.x before 6.0.14, 6.1.x before 6.1.13, 6.2.x before 6.2.14, 6.3.x before 6.3.10, 6.4.x before 6.4.7, and 6.5.x before 6.5.3; and Splunk Light before 6.6.0 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Splunk Enterprise 6.6.x, when configured to run as root but drop privileges to a specific non-root account, allows local users to gain privileges by leveraging access to that non-root account to modify $SPLUNK_HOME/etc/splunk-launch.conf and insert Trojan horse programs into $SPLUNK_HOME/bin, because the non-root setup instructions state that chown should be run across all of $SPLUNK_HOME to give non-root access.

Splunk through 7.0.1 allows information disclosure by appending __raw/services/server/info/server-info?output_mode=json to a query, as demonstrated by discovering a license key.
