Splunk

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.Show less

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.Show less

On Splunk Enterprise versions below 9.0.5, 8.2.11, and 8.1.14, and in Splunk Cloud Platform versions below 9.0.2303.100, an unauthorized user can access the {{/services/indexing/preview}} REST endpoint to overwrite search results if they know the search ID (SID) of an existing search job.Show less

In Splunk Enterprise versions below 9.0.5, 8.2.11, and 8.1.14, and Splunk Cloud Platform versions below 9.0.2303.100, an attacker can exploit a vulnerability in the {{dump}} SPL command to cause a denial of service by crashing the Splunk daemon.Show less

In the Splunk App for Lookup File Editing versions below 4.0.1, a low-privileged user can, with a specially crafted web request, trigger a path traversal exploit that can then be used to read and write to restricted areas of the Splunk installation directory.Show less

In Splunk Enterprise versions below 9.1.0.2, 9.0.5.1, and 8.2.11.2, an attacker can inject American National Standards Institute (ANSI) escape codes into Splunk log files that, when a vulnerable terminal application reads them, can potentially, at worst, result in possible code execution in the vulnerable application. This attack requires a user to use a terminal application that supports the translation of ANSI escape codes to read the malicious log file locally in the vulnerable terminal, and to perform additional user interaction to exploit. Universal Forwarder versions 9.1.0.1, 9.0.5, 8.2.11, and lower can be vulnerable in situations where they have management services active and accessible over the network. Universal Forwarder versions 9.0.x and 9.1.x bind management services to the local machine and are not vulnerable in this specific configuration. See SVD-2022-0605 for more information. Universal Forwarder versions 9.1 use Unix Domain Sockets (UDS) for communication, which further reduces the potential attack surface. The vulnerability does not directly affect Splunk Enterprise or Universal Forwarder. The indirect impact on Splunk Enterprise and Universal Forwarder can vary significantly depending on the permissions in the vulnerable terminal application and where and how the user reads the malicious log file. For example, users can copy the malicious file from the Splunk Enterprise instance and read it on their local machine.Show less

In Splunk Enterprise versions below 9.0.5, 8.2.11, and 8.1.14, a Splunk dashboard view lets a low-privileged user exploit a vulnerability in the Bootstrap web framework (CVE-2019-8331) and build a stored cross-site scripting (XSS) payload.Show less

In Splunk Enterprise versions below 9.0.5, 8.2.11, and 8.1.14, and in Splunk Cloud Platform versions below 9.0.2303.100, a low-privileged user can perform an unauthorized transfer of data from a search using the ‘copyresults’ command if they know the search ID (SID) of a search job that has recently run.Show less

In Splunk Enterprise versions below 9.0.5, 8.2.11. and 8.1.14, and Splunk Cloud Platform versions below 9.0.2303.100, a low-privileged user who holds the ‘user’ role can see the hashed version of the initial user name and password for the Splunk instance by using the ‘rest’ SPL command against the ‘conf-user-seed’ REST endpoint.Show less

In Splunk Enterprise versions below 9.0.5, 8.2.11, and 8.1.14, and Splunk Cloud Platform versions below 9.0.2303.100, a low-privileged user can trigger an HTTP response splitting vulnerability with the ‘rest’ SPL command that lets them potentially access other REST endpoints in the system arbitrarily.Show less

In versions of Splunk Enterprise below 9.0.5, 8.2.11, and 8.1.14, and Splunk Cloud Platform below version 9.0.2303.100, a low-privileged user who holds a role that has the ‘edit_user’ capability assigned to it can escalate their privileges to that of the admin user by providing specially crafted web requests.Show less

On Splunk Enterprise versions below 9.0.5, 8.2.11, and 8.1.14, an unauthenticated attacker can send specially-crafted messages to the XML parser within SAML authentication to cause a denial of service in the Splunk daemon.Show less

In Splunk Enterprise versions below 8.1.13, 8.2.10, and 9.0.4, a cross-site request forgery in the Splunk Secure Gateway (SSG) app in the ‘kvstore_client’ REST endpoint lets a potential attacker update SSG KV store collections using an HTTP GET request.Show less

In Splunk Enterprise versions below 8.1.13, 8.2.10, and 9.0.4, aliases of the ‘collect’ search processing language (SPL) command, including ‘summaryindex’, ‘sumindex’, ‘stash’,’ mcollect’, and ‘meventcollect’, were not designated as safeguarded commands. The commands could potentially allow for the exposing of data to a summary index that unprivileged users could access. The vulnerability requires a higher privileged user to initiate a request within their browser, and only affects instances with Splunk Web enabled.Show less

In Splunk Enterprise versions below 8.1.13, 8.2.10, and 9.0.4, the ‘map’ search processing language (SPL) command lets a search bypass SPL safeguards for risky commands. The vulnerability requires a higher privileged user to initiate a request within their browser and only affects instances with Splunk Web enabled.Show less

In Splunk Enterprise versions below 8.1.13, 8.2.10, and 9.0.4, the ‘sendemail’ REST API endpoint lets any authenticated user send an email as the Splunk instance. The endpoint is now restricted to the ‘splunk-system-user’ account on the local instance.Show less

In Splunk Enterprise versions below 8.1.13, 8.2.10, and 9.0.4, the lookup table upload feature let a user upload lookup tables with unnecessary filename extensions. Lookup table file extensions may now be one of the following only: .csv, .csv.gz, .kmz, .kml, .mmdb, or .mmdb.gzl.Show less

In Splunk Enterprise versions below 8.1.13, 8.2.10, and 9.0.4, the ‘search_listener’ parameter in a search allows for a blind server-side request forgery (SSRF) by an authenticated user. The initiator of the request cannot see the response without the presence of an additional vulnerability within the environment.Show less
