In Splunk Enterprise versions below 9.2.3 and 9.1.6 and Splunk Cloud Platform versions below 9.2.2403.108 and 9.1.2312.205, a low-privileged user that does not hold the "admin" or "power" Splunk roles could create a malicious payload through a custom configuration file that the "api.uri" parameter from the "/manager/search/apps/local" endpoint in Splunk Web calls. This could result in execution of unauthorized JavaScript code in the browser of a user.

In Splunk Enterprise versions 9.3.0, 9.2.3, and 9.1.6, a low-privileged user that does not hold the "admin" or "power" Splunk roles could view images on the machine that runs Splunk Enterprise by using the PDF export feature in Splunk classic dashboards. The images on the machine could be exposed by exporting the dashboard as a PDF, using the local image path in the img tag in the source extensible markup language (XML) code for the Splunk classic dashboard.

In Splunk Enterprise versions below 9.2.3 and 9.1.6 and Splunk Cloud Platform versions below 9.2.2403, a low-privileged user that does not hold the "admin" or "power" Splunk roles could craft a malicious payload through Scheduled Views that could result in execution of unauthorized JavaScript code in the browser of a user.

In Splunk Enterprise for Windows versions below 9.3.1, 9.2.3, and 9.1.6, a low-privileged user that does not hold the "admin" or "power" Splunk roles could write a file to the Windows system root directory, which has a default location in the Windows System32 folder, when Splunk Enterprise for Windows is installed on a separate drive.

In Splunk Enterprise versions below 9.2.3 and 9.1.6, and Splunk Secure Gateway versions on Splunk Cloud Platform versions below 3.4.259, 3.6.17, and 3.7.0, a low-privileged user that does not hold the "admin" or "power" Splunk roles can see App Key Value Store (KV Store) deployment configuration and public/private keys in the Splunk Secure Gateway App.

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 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 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.

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 versions below 9.2.2, 9.1.5, and 9.0.10, a low-privileged user that does not hold the admin or power Splunk roles could cause a Remote Code Execution through an external lookup that references the “splunk_archiver“ application.

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 on Windows, an authenticated user could execute a specially crafted query that they could then use to serialize untrusted data. The attacker could use the query to execute arbitrary code.

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, an authenticated user could run risky commands using the permissions of a higher-privileged user to bypass SPL safeguards for risky commands in the Analytics Workspace. The vulnerability requires the authenticated user 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.

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 and 9.1.2308.207, an authenticated user could create an external lookup that calls a legacy internal function. The authenticated user could use this internal function to insert code into the Splunk platform installation directory. From there, the user could execute arbitrary code on the Splunk platform Instance.

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 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, 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 9.2.1, 9.1.4, and 9.0.9, the software potentially exposes authentication tokens during the token validation process. This exposure happens when either Splunk Enterprise runs in debug mode or the JsonWebToken component has been configured to log its activity at the DEBUG logging level.

In Splunk Enterprise versions below 9.2.1, 9.1.4, and 9.0.9, the Dashboard Examples Hub lacks protections for risky SPL commands. This could let attackers bypass SPL safeguards for risky commands in the Hub. The vulnerability would require the attacker to phish the victim by tricking them into initiating a request within their browser.

In Splunk Enterprise for Windows versions below 9.0.8 and 9.1.3, Splunk Enterprise does not correctly sanitize path input data. This results in the unsafe deserialization of untrusted data from a separate disk partition on the machine. This vulnerability only affects Splunk Enterprise for Windows.

In Splunk versions below 9.0.8 and 9.1.3, the “mrollup” SPL command lets a low-privileged user view metrics on an index that they do not have permission to view. This vulnerability requires user interaction from a high-privileged user to exploit.

In Splunk Enterprise versions below 9.0.8, the Splunk RapidDiag utility discloses server responses from external applications in a log file.

In Splunk Enterprise versions below 9.0.8 and 9.1.3, Splunk app key value store (KV Store) improperly handles permissions for users that use the REST application programming interface (API). This can potentially result in the deletion of KV Store collections.

In Splunk Enterprise Security (ES) versions below 7.1.2, an attacker can use investigation attachments to perform a denial of service (DoS) to the Investigation. The attachment endpoint does not properly limit the size of the request which lets an attacker cause the Investigation to become inaccessible.

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.<br>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.

In Splunk Enterprise versions below 9.0.7 and 9.1.2, ineffective escaping in the “Show syntax Highlighted” feature can result in the execution of unauthorized code in a user’s web browser.

In Splunk Enterprise versions below 9.0.7 and 9.1.2, Splunk Enterprise does not safely sanitize extensible stylesheet language transformations (XSLT) that users supply. This means that an attacker can upload malicious XSLT which can result in remote code execution on the Splunk Enterprise instance.

In Splunk Enterprise versions lower than 8.2.12, 9.0.6, and 9.1.1, an attacker can exploit an absolute path traversal to execute arbitrary code that is located on a separate disk.

In Splunk Enterprise versions earlier than 8.2.12, 9.0.6, and 9.1.1, a dynamic link library (DLL) that ships with Splunk Enterprise references an insecure path for the OPENSSLDIR build definition. An attacker can abuse this reference and subsequently install malicious code to achieve privilege escalation on the Windows machine.

In Splunk Enterprise versions lower than 9.0.6 and 8.2.12, a malicious actor can send a malformed security assertion markup language (SAML) request to the `/saml/acs` REST endpoint which can cause a denial of service through a crash or hang of the Splunk daemon.

In Splunk Enterprise versions lower than 8.2.12, 9.0.6, and 9.1.1, an attacker can use the `printf` SPL function to perform a denial of service (DoS) against the Splunk Enterprise instance.

In Splunk IT Service Intelligence (ITSI) versions below below 4.13.3, 4.15.3, or 4.17.1, a malicious actor can inject American National Standards Institute (ANSI) escape codes into Splunk ITSI log files that, when a vulnerable terminal application reads them, can run malicious code in the vulnerable application. This attack requires a user to use a terminal application that translates ANSI escape codes to read the malicious log file locally in the vulnerable terminal. The vulnerability also requires additional user interaction to succeed. The vulnerability does not directly affect Splunk ITSI. The indirect impact on Splunk ITSI can vary significantly depending on the permissions in the vulnerable terminal application, as well as where and how the user reads the malicious log file. For example, users can copy the malicious file from Splunk ITSI and read it on their local machine.

In Splunk Enterprise versions below 9.1.1, 9.0.6, and 8.2.12, an attacker can craft a special web request that can result in reflected cross-site scripting (XSS) on the “/app/search/table” web endpoint. Exploitation of this vulnerability can lead to the execution of arbitrary commands on the Splunk platform instance.

In Splunk Enterprise versions lower than 8.2.12, 9.0.6, and 9.1.1, an attacker can execute a specially crafted query that they can then use to serialize untrusted data. The attacker can use the query to execute arbitrary code.

In Splunk Enterprise versions below 8.2.12, 9.0.6, and 9.1.1, an attacker can create an external lookup that calls a legacy internal function. The attacker can use this internal function to insert code into the Splunk platform installation directory. From there, a user can execute arbitrary code on the Splunk platform Instance.
