Denial of Service in Splunk Enterprise Security of the Investigations manager
through Investigation creation
Advisory ID: SVD-2024-0102
CVE ID: CVE-2024-22165
Published: 2024-01-09
Last Update: 2024-01-09
CVSSv3.1 Score: 6.5, Medium
CVSSv3.1 Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
CWE: CWE-20
Bug ID: SOLNESS-35977
Description
In Splunk Enterprise Security (ES) versions lower than 7.1.2, an attacker can
create a malformed Investigation to perform a denial of service (DoS). The
malformed investigation prevents the generation and rendering of the
Investigations manager until it is deleted.
The vulnerability requires an authenticated session and access to create an
Investigation. It only affects the availability of the Investigations manager,
but without the manager, the Investigations functionality becomes unusable for
most users.
Solution
Upgrade Splunk Enterprise Security (ES) to version 7.1.2, 7.2.0, 7.3.0 or
higher.
