Advisory ID: SVD-2024-0102

CVSSv3.1 Score: 6.5, Medium


Bug ID: SOLNESS-35977


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.


Upgrade Splunk Enterprise Security (ES) to version 7.1.2, 7.2.0, 7.3.0 or higher.
