Title
Improper Input Validation in "label" column field in Splunk Secure Gateway App
Summary
In Splunk Enterprise versions below 10.0.2, 9.4.6, 9.3.8, and 9.2.10, and versions below 3.9.10, 3.8.58 and 3.7.28 of the Splunk Secure Gateway app on Splunk Cloud Platform, a low-privileged user that does not hold the "admin" or "power" Splunk roles could craft a malicious payload through the `label` column field after adding a new device in the Splunk Secure Gateway app. This could potentially lead to a client-side denial of service (DoS).
Severity ?
4.3 (Medium)
CWE
- CWE-20 - The product does not validate or incorrectly validates input that can affect the control flow or data flow of a program.

Title
URL validation bypass through Views Dashboard in Splunk Enterprise
Summary
In Splunk Enterprise versions below 10.0.2, 9.4.6, 9.3.8, and 9.2.10, and Splunk Cloud Platform versions below 10.1.2507.10, 10.0.2503.8, and 9.3.2411.120, a low-privileged user that does not hold the "admin" or "power" Splunk roles could create a views dashboard with a custom background using the `data:image/png;base64` protocol that could potentially lead to an unvalidated redirect. This behavior circumvents the Splunk external URL warning mechanism by using a specially crafted URL, allowing for a redirection to an external malicious site. The vulnerability requires the attacker to phish the victim by tricking them into initiating a request within their browser. The authenticated user should not be able to exploit the vulnerability at will.
Severity ?
CWE
- CWE-601 - A web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a Redirect. This simplifies phishing attacks.

Title
Incorrect permission assignment on Splunk Enterprise for Windows during new installation or upgrade
Summary
In Splunk Enterprise for Windows versions below 10.0.2, 9.4.6, 9.3.8, and 9.2.10, a new installation of or an upgrade to an affected version can result in incorrect permissions assignment in the Splunk Enterprise for Windows Installation directory. This lets non-administrator users on the machine access the directory and all its contents.
Severity ?
CWE
- CWE-732 - The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.

Unauthenticated Log Injection in Splunk Enterprise
Summary
In Splunk Enterprise versions below 10.0.1, 9.4.6, 9.3.8, and 9.2.10, and Splunk Cloud Platform versions below 10.1.2507.4, 10.0.2503.6, and 9.3.2411.117.125, an unauthenticated attacker can inject American National Standards Institute (ANSI) escape codes into Splunk log files due to improper validation at the /en-US/static/ web endpoint. This may allow them to poison, forge, or obfuscate sensitive log data through specially crafted HTTP requests, potentially impacting log integrity and detection capabilities.
Severity ?

Summary
In Splunk Enterprise versions below 10.0.2, 9.4.6, 9.3.8, and 9.2.10, and Splunk Cloud Platform versions below 10.1.2507.6, 10.0.2503.7, and 9.3.2411.117, a user who holds a role with a high privilege capability `admin_all_objects` could craft a malicious payload through the href attribute of an anchor tag within a collection in the navigation bar, which could result in execution of unauthorized JavaScript code in the browser of a user.
Severity ?
CWE
- CWE-79 - The software does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
