Description

According to its version number, the Splunk Enterprise hosted on the remote web server is 6.0.x prior to 6.0.7. It is, therefore, affected by the following vulnerabilities :

  • A man-in-the-middle (MitM) information disclosure vulnerability, known as POODLE, exists due to the way SSL 3.0 handles padding bytes when decrypting messages encrypted using block ciphers in cipher block chaining (CBC) mode. A MitM attacker can decrypt a selected byte of a cipher text in as few as 256 tries if they are able to force a victim application to repeatedly send the same data over newly created SSL 3.0 connections. (CVE-2014-3566)

  • A flaw exists in the included OpenSSL library due to handling session tickets that have not been properly verified for integrity. A remote attacker, by using a large number of invalid session tickets, can exploit this to cause a denial of service. (CVE-2014-3567)

  • A cross-site scripting flaw exists within the Dashboard due to improperly validating input. This allows a remote attacker, using a specially crafted request, to execute arbitrary script code in the user
