In Splunk Enterprise versions below 8.1.13, 8.2.10, and 9.0.4, a cross-site request forgery in the Splunk Secure Gateway (SSG) app in the ‘kvstore_client’ REST endpoint lets a potential attacker update SSG KV store collections using an HTTP GET request.

In Splunk Enterprise versions below 8.1.13, 8.2.10, and 9.0.4, a cross-site request forgery in the Splunk Secure Gateway (SSG) app in the ‘kvstore_client’ REST endpoint lets a potential attacker update SSG [App Key Value Store (KV store)](https://docs.splunk.com/Documentation/Splunk/latest/Admin/AboutKVstore) collections using an HTTP GET request. SSG is a Splunk-built app that comes with Splunk Enterprise. The vulnerability affects instances with SSG and Splunk Web enabled.

Ein Angreifer kann mehrere Schwachstellen in Splunk Splunk Enterprise ausnutzen, um vertrauliche Informationen offenzulegen, Sicherheitsmaßnahmen zu umgehen, einen Denial-of-Service-Zustand zu verursachen, Daten zu manipulieren und einen Cross-Site-Scripting-Angriff durchzuführen.
