Splunk: Security Vulnerabilities
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who does not hold the "admin" or "power" Splunk roles could bypass Search Processing Language (SPL) safeguards for risky commands through the Job Details dashboard. The injected SPL could run using the permissions of an authenticated user who opens a crafted Job Details dashboard link. This could allow access to all relevant data and affect system integrity within those permissions. The vulnerability is possible because the Job Details dashboard does not correctly neutralize a caller-supplied search identifier before placing it into SPL searches. The vulnerability requires the attacker to phish the user by tricking them into opening the crafted link. The user who does not hold the "admin" or "power" Splunk roles should not be able to exploit the vulnerability at will. For more information see About jobs and job management (https://help.splunk.com/en/splunk-enterprise/search/search-manual/10.4/manage-jobs/about-jobs-and-job-management) in the Splunk documentation.

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who holds the "power" Splunk role could create a malicious Splunk Web tour and cause arbitrary JavaScript to run in the browser of another user when that user opens a crafted tour link. The JavaScript runs in the browser of the affected user, allowing for access to all relevant data available to that user. The Cross-Site Scripting (XSS) vulnerability is possible because Splunk Web renders tour content and tour navigation links without sufficient output encoding and accepts a tour selector value that can be treated as markup. The vulnerability requires another user to open a crafted tour link. The user who holds the "power" Splunk role should not be able to trigger JavaScript execution in another user's browser without that user interaction.

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who holds the "power" Splunk role could store a malicious ui-tour knowledge object that matches an auto-tour page name and share the object at the app level. The object can execute arbitrary JavaScript in the browser of another authenticated user who visits a standard Splunk Web page. The JavaScript could expose all relevant data and affect system integrity within the second user permissions. The Cross-Site Scripting (XSS) vulnerability is possible because Splunk Web resolves auto-tour entries from the app namespace and uses untrusted tour content when building the tour image.

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who does not hold the "admin" or "power" Splunk roles could store a dashboard view that runs JavaScript in the browser of another user who opens it and hovers over a sparkline table cell, allowing for access to all relevant data and system integrity available to that user. The vulnerability is possible because the dashboard table renderer does not sufficiently restrict tooltip options or escape tooltip content before display.

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, and Splunk Secure Gateway versions below 3.10.9, 3.9.23, and 3.8.70, an unauthenticated user could trick a user who holds the "admin" or "sc_admin" Splunk roles into opening a crafted Splunk Web Uniform Resource Locator (URL). The resulting dashboard searches could run arbitrary Search Processing Language (SPL) commands with the permissions available to the affected user. The commands could expose all relevant data available to that user and affect search results or lookup data. The vulnerability is possible because Splunk Secure Gateway dashboards do not correctly neutralize caller-supplied values before using them in dashboard searches. The vulnerability requires the attacker to phish the affected user by tricking them into initiating a request within their browser. The unauthenticated user should not be able to exploit the vulnerability at will.

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who does not hold the "admin" or "power" Splunk roles could perform Remote Code Execution (RCE) by uploading a malicious knowledge bundle and causing it to be used by distributed search, which can allow for access to all relevant data and affect system integrity and availability. The vulnerability is possible because the Representational State Transfer (REST) API endpoint for knowledge bundle upload does not require the high-privilege capability edit_dist_peer, and distributed search accepts caller-supplied knowledge bundle selections from users who do not hold that capability. For more information see What search heads send to search peers (https://help.splunk.com/en/splunk-enterprise/administer/distributed-search/9.2/knowledge-bundle-replication/what-search-heads-send-to-search-peers), About configuring role-based user access (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/9.0/manage-splunk-platform-users-and-roles/about-configuring-role-based-user-access), Define roles on the Splunk platform with capabilities (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/9.1/manage-splunk-platform-users-and-roles/define-roles-on-the-splunk-platform-with-capabilities), and Using the REST API reference (https://help.splunk.com/en/splunk-enterprise/rest-api-reference/10.4/introduction/using-the-rest-api-reference) in the Splunk documentation.

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who does not hold the "admin" or "power" Splunk roles could perform Remote Code Execution (RCE) by submitting crafted Splunk Web Manager Configuration content. The user could then access all relevant data and affect system integrity and availability. The vulnerability is possible because Splunk Web evaluates manager Extensible Markup Language expressions without sufficient input restrictions, and the associated configuration route does not require the capability expected for manager configuration changes.

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who does not hold the "admin" or "power" Splunk roles could execute arbitrary code on the Splunk platform instance through Splunk Web Manager Configuration. The user could then access all relevant data and affect system integrity and availability on the Splunk platform instance. The vulnerability is possible because Splunk Web Manager Configuration evaluates manager configuration values, and the Representational State Transfer (REST) API path for manager configuration does not require the permission that normally controls manager configuration writes.

In Splunk Enterprise versions below 10.4.1, 10.2.5, 10.0.9, and 9.4.14, an unauthenticated user who can reach the Splunk management port could store a Search Processing Language (SPL) pipeline that runs when an administrator opens the Add Data forwarder workflow. The SPL pipeline could access all relevant data, affect system integrity, and affect availability of the Splunk platform instance. The SPL injection is possible because Deployment Server client identifiers are placed into dispatched searches without neutralizing special characters. Successful exploitation requires an administrator to open the affected Add Data forwarder workflow after the unauthenticated user registers a crafted Deployment Server client identity. For more information see Forward data (https://help.splunk.com/en/splunk-enterprise/get-started/get-data-in/10.2/how-to-get-data-into-your-splunk-deployment/forward-data) and About agent management (https://help.splunk.com/en/splunk-enterprise/administer/update-your-deployment/10.4/agent-management/about-agent-management) in the Splunk documentation.

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who does not hold the "admin" or "power" Splunk roles could move files that the user account running Splunk Enterprise can read into a lookup that the user controls. The user could then access all relevant data and affect system integrity and availability on the search head. The vulnerability is possible because the lookup configuration endpoint does not resolve lookup source paths before checking whether they stay inside the allowed lookup staging area. For more information see About lookups (https://help.splunk.com/en/splunk-enterprise/manage-knowledge-objects/knowledge-management-manual/10.4/use-lookups-in-splunk-web/about-lookups) and Define roles on the Splunk platform with capabilities (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.4/manage-splunk-platform-users-and-roles/define-roles-on-the-splunk-platform-with-capabilities) in the Splunk documentation.
