|---|---|---|---|---|---|
| CVE-2021-3422 | The lack of validation of a key-value field in the Splunk-to-Splunk protocol results in a denial-of-service in Splunk Enterprise instances configured to index Universal Forwarder traffic. The vulnerability impacts Splunk Enterprise versions before 7.3.9, 8.0 versions before 8.0.9, and 8.1 versions before 8.1.3. It does not impact Universal Forwarders. When Splunk forwarding is secured using TLS or a Token, the attack requires compromising the certificate or token, or both. Implementation of eith | 7.5 | 0.40% | 2022-03-25 | 2024-11-21 |
| CVE-2021-26253 | A potential vulnerability in Splunk Enterprise's implementation of DUO MFA allows for bypassing the MFA verification in Splunk Enterprise versions before 8.1.6.

| CVE-2021-42743 | A misconfiguration in the node default path allows for local privilege escalation from a lower privileged user to the Splunk user in Splunk Enterprise versions before 8.1.1 on Windows. | 8.8 | 0.12% | 2022-05-06 | 2024-11-21 |
| CVE-2022-26070 | When handling a mismatched pre-authentication cookie, the application leaks the internal error message in the response, which contains the Splunk Enterprise local system path. The vulnerability impacts Splunk Enterprise versions before 8.1.0. | 4.3 | 0.26% | 2022-05-06 | 2024-11-21 |
| CVE-2022-26889 | In Splunk Enterprise versions before 8.1.2, the uri path to load a relative resource within a web page is vulnerable to path traversal. It allows an attacker to potentially inject arbitrary content into the web page (e.g., HTML Injection, XSS) or bypass SPL safeguards for risky commands. The attack is browser-based. An attacker cannot exploit the attack at will and requires the attacker to initiate a request within the victim's browser (e.g., phishing). | 8.8 | 0.12% | 2022-05-06 | 2024-11-21 |
| CVE-2022-27183 | The Monitoring Console app configured in Distributed mode allows for a Reflected XSS in a query parameter in Splunk Enterprise versions before 8.1.4. The Monitoring Console app is a bundled app included in Splunk Enterprise, not for download on SplunkBase, and not installed on Splunk Cloud Platform instances. Note that the Cloud Monitoring Console is not impacted. | 8.8 | 0.35% | 2022-05-06 | 2024-11-21 |
| CVE-2022-32151 | The httplib and urllib Python libraries that Splunk shipped with Splunk Enterprise did not validate certificates using the certificate authority (CA) certificate stores by default in Splunk Enterprise versions before 9.0 and Splunk Cloud Platform versions before 8.2.2203. Python 3 client libraries now verify server certificates by default and use the appropriate CA certificate stores for each library. Apps and add-ons that include their own HTTP libraries are not affected. For Splunk Enterprise, | 7.4 | 0.20% | 2022-06-15 | 2024-11-21 |
| CVE-2022-32152 | Splunk Enterprise peers in Splunk Enterprise versions before 9.0 and Splunk Cloud Platform versions before 8.2.2203 did not validate the TLS certificates during Splunk-to-Splunk communications by default. Splunk peer communications configured properly with valid certificates were not vulnerable. However, an attacker with administrator credentials could add a peer without a valid certificate and connections from misconfigured nodes without valid certificates did not fail by default. For Splunk En | 8.1 | 0.48% | 2022-06-15 | 2024-11-21 |
| CVE-2022-32153 | Splunk Enterprise peers in Splunk Enterprise versions before 9.0 and Splunk Cloud Platform versions before 8.2.2203 did not validate the TLS certificates during Splunk-to-Splunk communications by default. Splunk peer communications configured properly with valid certificates were not vulnerable. However, an attacker with administrator credentials could add a peer without a valid certificate and connections from misconfigured nodes without valid certificates did not fail by default. For Splunk En | 8.1 | 0.30% | 2022-06-15 | 2024-11-21 |
| CVE-2022-32154 | Dashboards in Splunk Enterprise versions before 9.0 might let an attacker inject risky search commands into a form token when the token is used in a query in a cross-origin request. The result bypasses SPL safeguards for risky commands. See New capabilities can limit access to some custom and potentially risky commands (https://docs.splunk.com/Documentation/Splunk/9.0.0/Security/SPLsafeguards#New_capabilities_can_limit_access_to_some_custom_and_potentially_risky_commands) for more information.

| CVE-2022-32155 | In universal forwarder versions before 9.0, management services are available remotely by default. When not required, it introduces a potential exposure, but it is not a vulnerability. If exposed, we recommend each customer assess the potential severity specific to your environment. In 9.0, the universal forwarder now binds the management port to localhost preventing remote logins by default. If management services are not required in versions before 9.0, set disableDefaultPort = true in server. | 7.5 | 0.43% | 2022-06-15 | 2024-11-21 |
| CVE-2022-32156 | In Splunk Enterprise and Universal Forwarder versions before 9.0, the Splunk command-line interface (CLI) did not validate TLS certificates while connecting to a remote Splunk platform instance by default. After updating to version 9.0, see Configure TLS host name validation for the Splunk CLI https://docs.splunk.com/Documentation/Splunk/9.0.0/Security/EnableTLSCertHostnameValidation#Configure_TLS_host_name_validation_for_the_Splunk_CLI to enable the remediation.

| CVE-2022-32157 | Splunk Enterprise deployment servers in versions before 9.0 allow unauthenticated downloading of forwarder bundles. Remediation requires you to update the deployment server to version 9.0 and Configure authentication for deployment servers and clients (https://docs.splunk.com/Documentation/Splunk/9.0.0/Security/ConfigDSDCAuthEnhancements#Configure_authentication_for_deployment_servers_and_clients). Once enabled, deployment servers can manage only Universal Forwarder versions 9.0 and higher. Thou | 7.5 | 0.50% | 2022-06-15 | 2024-11-21 |
| CVE-2022-32158 | Splunk Enterprise deployment servers in versions before 8.1.10.1, 8.2.6.1, and 9.0 let clients deploy forwarder bundles to other deployment clients through the deployment server. An attacker that compromised a Universal Forwarder endpoint could use the vulnerability to execute arbitrary code on all other Universal Forwarder endpoints subscribed to the deployment server. | 9.0 | 1.22% | 2022-06-15 | 2024-11-21 |
| CVE-2022-37437 | When using Ingest Actions to configure a destination that resides on Amazon Simple Storage Service (S3) in Splunk Web, TLS certificate validation is not correctly performed and tested for the destination. The vulnerability only affects connections between Splunk Enterprise and an Ingest Actions Destination through Splunk Web and only applies to environments that have configured TLS certificate validation. It does not apply to Destinations configured directly in the outputs.conf configuration fil | 7.4 | 0.19% | 2022-08-16 | 2024-11-21 |
| CVE-2022-37438 | In Splunk Enterprise versions in the following table, an authenticated user can craft a dashboard that could potentially leak information (for example, username, email, and real name) about Splunk users, when visited by another user through the drilldown component. The vulnerability requires user access to create and share dashboards using Splunk Web. | 2.6 | 0.34% | 2022-08-16 | 2024-11-21 |
| CVE-2022-37439 | In Splunk Enterprise and Universal Forwarder versions in the following table, indexing a specially crafted ZIP file using the file monitoring input can result in a crash of the application. Attempts to restart the application would result in a crash and would require manually removing the malformed file. | 5.5 | 0.11% | 2022-08-16 | 2024-11-21 |
| CVE-2022-43561 | In Splunk Enterprise versions below 8.1.12, 8.2.9, and 9.0.2, a remote user that holds the “power” Splunk role can store arbitrary scripts that can lead to persistent cross-site scripting (XSS).
