Splunk vulnerabilities

GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference vulnerability has been discovered in the gst_matroska_demux_parse_blockgroup_or_simpleblock function within matroska-demux.c. This function does not properly check the validity of the GstBuffer *sub pointer before performing dereferences. As a result, null pointer dereferences may occur. This vulnerability is fixed in 1.24.10.

In Splunk Enterprise versions below 9.3.2, 9.2.4, and 9.1.7 and Splunk Cloud Platform versions below 9.3.2408.101, 9.2.2406.106, 9.2.2403.111, and 9.1.2312.206, an SPL command can potentially disclose sensitive information. The vulnerability requires the exploitation of another vulnerability, such as a Risky Commands Bypass, for successful exploitation.

In Splunk Enterprise versions below 9.3.2, 9.2.4, and 9.1.7, and versions below 3.4.261 and 3.7.13 of the Splunk Secure Gateway app on Splunk Cloud Platform, a low-privileged user that does not hold the “admin“ or “power“ Splunk roles could perform a Remote Code Execution (RCE).

In Splunk Enterprise versions below 9.3.0, 9.2.4, and 9.1.7 and Splunk Cloud Platform versions below 9.1.2312.206, a low-privileged user that does not hold the “admin“ or “power“ Splunk roles, that has a username with the same name as a role with read access to dashboards, could see the dashboard name and the dashboard XML by cloning the dashboard.

In Splunk Enterprise versions below 9.3.2, 9.2.4, and 9.1.7 and Splunk Cloud Platform versions below 9.2.2406.107, 9.2.2403.109, and 9.1.2312.206, a low-privileged user that does not hold the “admin“ or “power“ Splunk roles could run a saved search with a risky command using the permissions of a higher-privileged user to bypass the SPL safeguards for risky commands on “/en-US/app/search/report“ endpoint through “s“ parameter.<br>The vulnerability requires the attacker 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.

Tornado is a Python web framework and asynchronous networking library. The algorithm used for parsing HTTP cookies in Tornado versions prior to 6.4.2 sometimes has quadratic complexity, leading to excessive CPU consumption when parsing maliciously-crafted cookie headers. This parsing occurs in the event loop thread and may block the processing of other requests. Version 6.4.2 fixes the issue.

Versions of the package cross-spawn before 6.0.6, from 7.0.0 and before 7.0.5 are vulnerable to Regular Expression Denial of Service (ReDoS) due to improper input sanitization. An attacker can increase the CPU usage and crash the program by crafting a very large and well crafted string.

Werkzeug is a Web Server Gateway Interface web application library. Applications using `werkzeug.formparser.MultiPartParser` corresponding to a version of Werkzeug prior to 3.0.6 to parse `multipart/form-data` requests (e.g. all flask applications) are vulnerable to a relatively simple but effective resource exhaustion (denial of service) attack. A specifically crafted form submission request can cause the parser to allocate and block 3 to 8 times the upload size in main memory. There is no upper limit; a single upload at 1 Gbit/s can exhaust 32 GB of RAM in less than 60 seconds. Werkzeug version 3.0.6 fixes this issue.

In Splunk Enterprise versions below 9.2.3 and 9.1.6 and Splunk Cloud Platform versions below 9.2.2403.108 and 9.1.2312.205, a low-privileged user that does not hold the "admin" or "power" Splunk roles could create a malicious payload through a custom configuration file that the "api.uri" parameter from the "/manager/search/apps/local" endpoint in Splunk Web calls. This could result in execution of unauthorized JavaScript code in the browser of a user.

In Splunk Enterprise versions below 9.2.3 and 9.1.6 and Splunk Cloud Platform versions below 9.2.2403, a low-privileged user that does not hold the "admin" or "power" Splunk roles could craft a malicious payload through Scheduled Views that could result in execution of unauthorized JavaScript code in the browser of a user.

In Splunk Enterprise versions below 9.3.1, 9.2.3, and 9.1.6, the software potentially exposes plaintext passwords for local native authentication Splunk users. This exposure could happen when you configure the Splunk Enterprise AdminManager log channel at the DEBUG logging level.

In Splunk Enterprise versions below 9.3.1, 9.2.3, and 9.1.6, the software potentially exposes sensitive HTTP parameters to the `_internal` index. This exposure could happen if you configure the Splunk Enterprise `REST_Calls` log channel at the DEBUG logging level.

In Splunk Enterprise versions below 9.3.1, 9.2.3, and 9.1.6 and Splunk Cloud Platform versions below 9.2.2403.108, and 9.1.2312.204, a low-privileged user that does not hold the "admin" or "power" Splunk roles could change the maintenance mode state of App Key Value Store (KVStore) through a Cross-Site Request Forgery (CSRF).

In Splunk Enterprise versions below 9.3.1, 9.2.3, and 9.1.6 and Splunk Cloud Platform versions below 9.2.2403.107, 9.1.2312.204, and 9.1.2312.111, a low-privileged user that does not hold the "admin" or "power" Splunk roles could craft a search query with an improperly formatted "INGEST_EVAL" parameter as part of a [Field Transformation](https://docs.splunk.com/Documentation/Splunk/latest/Knowledge/Managefieldtransforms) which could crash the Splunk daemon (splunkd).

In Splunk Enterprise versions below 9.2.3 and 9.1.6, and Splunk Secure Gateway versions on Splunk Cloud Platform versions below 3.4.259, 3.6.17, and 3.7.0, a low-privileged user that does not hold the "admin" or "power" Splunk roles can see App Key Value Store (KV Store) deployment configuration and public/private keys in the Splunk Secure Gateway App.

In Splunk Enterprise versions 9.3.0, 9.2.3, and 9.1.6, a low-privileged user that does not hold the "admin" or "power" Splunk roles could view images on the machine that runs Splunk Enterprise by using the PDF export feature in Splunk classic dashboards. The images on the machine could be exposed by exporting the dashboard as a PDF, using the local image path in the img tag in the source extensible markup language (XML) code for the Splunk classic dashboard.

In Splunk Enterprise for Windows versions below 9.2.3 and 9.1.6, a low-privileged user that does not hold the "admin" or "power" Splunk roles could perform a Remote Code Execution (RCE) due to an insecure session storage configuration.

In Splunk Enterprise versions below 9.3.1, and 9.2.0 versions below 9.2.3, and Splunk Cloud Platform versions below 9.2.2403.103, 9.1.2312.200, 9.1.2312.110 and 9.1.2308.208, a low-privileged user that does not hold the "admin" or "power" Splunk roles could run a search as the "nobody" Splunk user in the SplunkDeploymentServerConfig app. This could let the low-privileged user access potentially restricted data.

In Splunk Enterprise for Windows versions below 9.3.1, 9.2.3, and 9.1.6, a low-privileged user that does not hold the "admin" or "power" Splunk roles could write a file to the Windows system root directory, which has a default location in the Windows System32 folder, when Splunk Enterprise for Windows is installed on a separate drive.

DOMPurify is a DOM-only, super-fast, uber-tolerant XSS sanitizer for HTML, MathML and SVG. DOMpurify was vulnerable to nesting-based mXSS. This vulnerability is fixed in 2.5.0 and 3.1.3.

The verify function in lib/elliptic/eddsa/index.js in the Elliptic package before 6.5.6 for Node.js omits "sig.S().gte(sig.eddsa.curve.n) || sig.S().isNeg()" validation.

An issue was discovered in Django 5.1 before 5.1.1, 5.0 before 5.0.9, and 4.2 before 4.2.16. The urlize() and urlizetrunc() template filters are subject to a potential denial-of-service attack via very large inputs with a specific sequence of characters.

DOMPurify is a DOM-only, super-fast, uber-tolerant XSS sanitizer for HTML, MathML and SVG. It has been discovered that malicious HTML using special nesting techniques can bypass the depth checking added to DOMPurify in recent releases. It was also possible to use Prototype Pollution to weaken the depth check. This renders dompurify unable to avoid cross site scripting (XSS) attacks. This issue has been addressed in versions 2.5.4 and 3.1.3 of DOMPurify. All users are advised to upgrade. There are no known workarounds for this vulnerability.

body-parser is Node.js body parsing middleware. body-parser <1.20.3 is vulnerable to denial of service when url encoding is enabled. A malicious actor using a specially crafted payload could flood the server with a large number of requests, resulting in denial of service. This issue is patched in 1.20.3.

axios 1.7.2 allows SSRF via unexpected behavior where requests for path relative URLs get processed as protocol relative URLs.

A vulnerability in the package_index module of pypa/setuptools versions up to 69.1.1 allows for remote code execution via its download functions. These functions, which are used to download packages from URLs provided by users or retrieved from package index servers, are susceptible to code injection. If these functions are exposed to user-controlled inputs, such as package URLs, they can execute arbitrary commands on the system. The issue is fixed in version 70.0.

In Splunk Enterprise versions below 9.2.2, 9.1.5, and 9.0.10 and Splunk Cloud Platform versions below 9.1.2312, an admin user could store and execute arbitrary JavaScript code in the browser context of another Splunk user through the conf-web/settings REST endpoint. This could potentially cause a persistent cross-site scripting (XSS) exploit.

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, an attacker could determine whether or not another user exists on the instance by deciphering the error response that they would likely receive from the instance when they attempt to log in. This disclosure could then lead to additional brute-force password-guessing attacks. This vulnerability would require that the Splunk platform instance uses the Security Assertion Markup Language (SAML) authentication scheme.

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, a low-privileged user that does not hold the admin or power Splunk roles could create experimental items.

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, a low-privileged user that does not hold the admin or power Splunk roles could craft a malicious payload through a View and Splunk Web Bulletin Messages that could result in execution of unauthorized JavaScript code in the browser of a user.

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, a low-privileged user that does not hold the admin or power Splunk roles could craft a malicious payload through a Splunk Web Bulletin Messages that could result in execution of unauthorized JavaScript code in the browser of a user.

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, a low-privileged user that does not hold the admin or power Splunk roles could craft a malicious payload through a View that could result in execution of unauthorized JavaScript code in the browser of a user. The “url” parameter of the Dashboard element does not have proper input validation to reject invalid URLs, which could lead to a Persistent Cross-site Scripting (XSS) exploit.

In Splunk Enterprise on Windows versions below 9.2.2, 9.1.5, and 9.0.10, an attacker could perform a path traversal on the /modules/messaging/ endpoint in Splunk Enterprise on Windows. This vulnerability should only affect Splunk Enterprise on Windows.

In Splunk Enterprise versions below 9.2.2, 9.1.5, and 9.0.10 and Splunk Cloud Platform versions below 9.2.2403.100, an authenticated, low-privileged user that does not hold the admin or power Splunk roles could send a specially crafted HTTP POST request to the datamodel/web REST endpoint in Splunk Enterprise, potentially causing a denial of service.

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 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 9.1.2312.200 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, a low-privileged user that does not hold the admin or power Splunk roles could cause a Remote Code Execution through an external lookup that references the “splunk_archiver“ application.

In Splunk Enterprise versions below 9.2.2, 9.1.5, and 9.0.10 on Windows, an authenticated user could execute a specially crafted query that they could then use to serialize untrusted data. The attacker could use the query to execute arbitrary code.

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 authenticated user could create an external lookup that calls a legacy internal function. The authenticated user could use this internal function to insert code into the Splunk platform installation directory. From there, the user could execute arbitrary code on the Splunk platform Instance.

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.

The various Is methods (IsPrivate, IsLoopback, etc) did not work as expected for IPv4-mapped IPv6 addresses, returning false for addresses which would return true in their traditional IPv4 forms.

Git is a revision control system. Prior to versions 2.45.1, 2.44.1, 2.43.4, 2.42.2, 2.41.1, 2.40.2, and 2.39.4, repositories with submodules can be crafted in a way that exploits a bug in Git whereby it can be fooled into writing files not into the submodule's worktree but into a `.git/` directory. This allows writing a hook that will be executed while the clone operation is still running, giving the user no opportunity to inspect the code that is being executed. The problem has been patched in versions 2.45.1, 2.44.1, 2.43.4, 2.42.2, 2.41.1, 2.40.2, and 2.39.4. If symbolic link support is disabled in Git (e.g. via `git config --global core.symlinks false`), the described attack won't work. As always, it is best to avoid cloning repositories from untrusted sources.

An issue was discovered in ECCurve.java and ECCurve.cs in Bouncy Castle Java (BC Java) before 1.78, BC Java LTS before 2.73.6, BC-FJA before 1.0.2.5, and BC C# .Net before 2.3.1. Importing an EC certificate with crafted F2m parameters can lead to excessive CPU consumption during the evaluation of the curve parameters.

In Splunk Enterprise versions below 9.2.1, 9.1.4, and 9.0.9, the Dashboard Examples Hub lacks protections for risky SPL commands. This could let attackers bypass SPL safeguards for risky commands in the Hub. The vulnerability would require the attacker to phish the victim by tricking them into initiating a request within their browser.

In Splunk Enterprise versions below 9.2.1, 9.1.4, and 9.0.9, the software potentially exposes authentication tokens during the token validation process. This exposure happens when either Splunk Enterprise runs in debug mode or the JsonWebToken component has been configured to log its activity at the DEBUG logging level.

Package jose aims to provide an implementation of the Javascript Object Signing and Encryption set of standards. An attacker could send a JWE containing compressed data that used large amounts of memory and CPU when decompressed by Decrypt or DecryptMulti. Those functions now return an error if the decompressed data would exceed 250kB or 10x the compressed size (whichever is larger). This vulnerability has been patched in versions 4.0.1, 3.0.3 and 2.6.3.

The protojson.Unmarshal function can enter an infinite loop when unmarshaling certain forms of invalid JSON. This condition can occur when unmarshaling into a message which contains a google.protobuf.Any value, or when the UnmarshalOptions.DiscardUnknown option is set.

The jose2go component before 1.6.0 for Go allows attackers to cause a denial of service (CPU consumption) via a large p2c (aka PBES2 Count) value.

Moby is an open-source project created by Docker to enable software containerization. The classic builder cache system is prone to cache poisoning if the image is built FROM scratch. Also, changes to some instructions (most important being HEALTHCHECK and ONBUILD) would not cause a cache miss. An attacker with the knowledge of the Dockerfile someone is using could poison their cache by making them pull a specially crafted image that would be considered as a valid cache candidate for some build steps. 23.0+ users are only affected if they explicitly opted out of Buildkit (DOCKER_BUILDKIT=0 environment variable) or are using the /build API endpoint. All users on versions older than 23.0 could be impacted. Image build API endpoint (/build) and ImageBuild function from github.com/docker/docker/client is also affected as it the uses classic builder by default. Patches are included in 24.0.9 and 25.0.2 releases.
