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, an authenticated, low-privileged user who does not hold the admin or power Splunk roles could upload a file with an arbitrary extension using the indexing/preview REST endpoint.

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 attacker could trigger a null pointer reference on the cluster/config REST endpoint, which could result in a crash of the Splunk daemon.

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 9.1.2312.200, 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 Add-on Builder versions below 4.1.4, the app writes sensitive information to internal log files.

In Splunk Add-on Builder versions below 4.1.4, the application writes user session tokens to its internal log files when you visit the Splunk Add-on Builder or when you build or edit a custom app or add-on.

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

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 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 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 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 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 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.

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.

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.

In Splunk Add-on Builder (AoB) versions below 4.1.2 and the Splunk CloudConnect SDK versions below 3.1.3, requests to third-party APIs through the REST API Modular Input incorrectly revert to using HTTP to connect after a failure to connect over HTTPS occurs.

libpcre in PCRE before 8.44 allows an integer overflow via a large number after a (?C substring.

libpcre in PCRE before 8.43 allows a subject buffer over-read in JIT when UTF is disabled, and \X or \R has more than one fixed quantifier, a related issue to CVE-2019-20454.
