Vulnerability from cvelistv5

Severity ?
7.3 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
CWE
  • CWE-77 - The software constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
Summary
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, an unauthenticated user could inject arbitrary Search Processing Language (SPL) into requests that search for events near a selected event. This could allow for unauthorized search execution. The vulnerability is possible because Splunk Web does not consistently escape caller-supplied values when it builds SPL for nearby-event searches, and embedded report access accepts those requests without the expected authorization check. For more information see Use time to find nearby events (https://help.splunk.com/en/splunk-enterprise/search/search-manual/10.2/specify-time-ranges/use-time-to-find-nearby-events) in the Splunk documentation.
