In Splunk Enterprise versions below 9.2.2, 9.1.5, and 9.0.10 and Splunk Cloud Platform versions below 9.1.2312, an admin user could store and execute arbitrary JavaScript code in the browser context of another Splunk user through the conf-web/settings REST endpoint. This could potentially cause a persistent cross-site scripting (XSS) exploit.
In Splunk Enterprise versions below 9.2.2, 9.1.5, and 9.0.10 and Splunk Cloud Platform versions below 9.1.2312.200 and 9.1.2308.207, a low-privileged user that does not hold the admin or power Splunk roles could craft a malicious payload through a View that could result in execution of unauthorized JavaScript code in the browser of a user. The “url” parameter of the Dashboard element does not have proper input validation to reject invalid URLs, which could lead to a Persistent Cross-site Scripting (XSS) exploit.
In Splunk Enterprise versions below 9.2.2, 9.1.5, and 9.0.10 and Splunk Cloud Platform versions below 9.1.2312.200 and 9.1.2308.207, a low-privileged user that does not hold the admin or power Splunk roles could craft a malicious payload through a Splunk Web Bulletin Messages that could result in execution of unauthorized JavaScript code in the browser of a user.
In Splunk Enterprise versions below 9.2.2, 9.1.5, and 9.0.10 and Splunk Cloud Platform versions below 9.1.2312.200 and 9.1.2308.207, a low-privileged user that does not hold the admin or power Splunk roles could craft a malicious payload through a View and Splunk Web Bulletin Messages that could result in execution of unauthorized JavaScript code in the browser of a user.
In Splunk Enterprise versions below 9.2.2, 9.1.5, and 9.0.10 and Splunk Cloud Platform versions below 9.1.2312.200 and 9.1.2308.207, a low-privileged user that does not hold the admin or power Splunk roles could create experimental items.
In Splunk Enterprise versions below 9.2.2, 9.1.5, and 9.0.10 and Splunk Cloud Platform versions below 9.1.2312.109, an attacker could determine whether or not another user exists on the instance by deciphering the error response that they would likely receive from the instance when they attempt to log in. This disclosure could then lead to additional brute-force password-guessing attacks. This vulnerability would require that the Splunk platform instance uses the Security Assertion Markup Language (SAML) authentication scheme.
In Splunk Enterprise versions below 9.2.2, 9.1.5, and 9.0.10 and Splunk Cloud Platform versions below 9.1.2312.200, an authenticated, low-privileged user who does not hold the admin or power Splunk roles could upload a file with an arbitrary extension using the indexing/preview REST endpoint.
In Splunk Enterprise versions below 9.2.2, 9.1.5, and 9.0.10 and Splunk Cloud Platform versions below 9.1.2312.200, a low-privileged user that does not hold the admin or power Splunk roles could create notifications in Splunk Web Bulletin Messages that all users on the instance receive.
In Splunk Enterprise versions below 9.2.2, 9.1.5, and 9.0.10 and Splunk Cloud Platform versions below 9.2.2403.100, an authenticated, low-privileged user that does not hold the admin or power Splunk roles could send a specially crafted HTTP POST request to the datamodel/web REST endpoint in Splunk Enterprise, potentially causing a denial of service.
In Splunk Enterprise on Windows versions below 9.2.2, 9.1.5, and 9.0.10, an attacker could perform a path traversal on the /modules/messaging/ endpoint in Splunk Enterprise on Windows. This vulnerability should only affect Splunk Enterprise on Windows.
