Splunk

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

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

Splunk SOAR versions lower than 6.1.0 are indirectly affected by a potential vulnerability accessed through the user’s terminal. A third party can send Splunk SOAR a maliciously crafted web request containing special ANSI characters to cause log file poisoning. When a terminal user attempts to view the poisoned logs, this can tamper with the terminal and cause possible malicious code execution from the terminal user’s action.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 user can insert potentially malicious JavaScript code into the app, which causes that code to run on the user’s machine. The app itself does not contain the potentially malicious JavaScript code. The vulnerability requires the attacker to phish the victim by tricking them into initiating a request within their browser, and requires additional user interaction to trigger. The attacker cannot exploit the vulnerability at will.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 App for Stream versions below 8.1.1, a low-privileged user could use a vulnerability in the streamfwd process within the Splunk App for Stream to escalate their privileges on the machine that runs the Splunk Enterprise instance, up to and including the root user.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
