CVE-2015-6515: Cross-site scripting (XSS) vulnerability in Splunk Web in Splunk Enterprise 6.2.x before 6.2.4, 6.1.x befor...

Security readout for executives and security teams

This is a stored or reflected web scripting risk in Splunk Web. An attacker could inject script or HTML through a header against vulnerable Splunk Enterprise or Splunk Light versions. For executives, the main concern is exposure of a security operations tool that often contains sensitive logs and privileged workflows. Exposure is likely limited to organizations still running the listed legacy Splunk Web versions. Risk increases when Splunk Web is reachable by untrusted users or networks. Prioritize remediation if Splunk Web is internet-accessible or used by privileged security staff. Legacy internal-only instances still need upgrade planning, but the public sources do not support emergency active-exploitation claims. Mitigation focus: Upgrade Splunk Enterprise to 6.2.4, 6.1.8, 6.0.9, or 5.0.13 or later.; Upgrade Splunk Light 6.2.x to 6.2.4 or later.; Restrict Splunk Web access to trusted networks until remediation is complete..
