CVE [?]: CVE-2017-5607
CPE [?]: cpe:/a:splunk:splunk

Synopsis

An application running on the remote web server is affected by multiple vulnerabilities.

Description

According to its self-reported version number, the version of Splunk running on the remote web server is Splunk Light 6.5.x prior to 6.5.3 or Splunk Enterprise 5.0.x prior to 5.0.18, 6.0.x prior to 6.0.14, 6.1.x prior to 6.1.13, 6.2.x prior to 6.2.13.1, 6.3.x prior to 6.3.10, 6.4.x prior to 6.4.6, or 6.5.x prior to 6.5.3. It is, therefore, affected by multiple vulnerabilities :

- An information disclosure vulnerability exists due to various system information being assigned to the global window property '$C' when a request is made to '/en-US/config?autoload=1'. An unauthenticated, remote attacker attacker can exploit this, by convincing user to visit a specially crafted web page, to disclose sensitive information. (CVE-2017-5607)

- A stored cross-site scripting (XSS) vulnerability exists in the web interface due to improper validation of unspecified input before returning to users. An authenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session.

- Multiple cross-site scripting (XSS) vulnerabilities exist due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit these vulnerabilities, via a specially crafted request, to execute arbitrary script code in a user's browser session. Note that these vulnerabilities only affect Splunk Enterprise 6.4.x prior to 6.4.7 and Splunk Light 6.5.x prior to 6.5.3. - An error message spoofing vulnerability exists that allows an unauthenticated, remote attacker to spoof the contents of error messages by convincing a user to visit a specially crafted website.

Solution

Upgrade to Splunk Enterprise version 5.0.18 / 6.0.14 / 6.1.13 / 6.2.13.1 / 6.3.10 / 6.4.6 / 6.5.3 or later.
