CVE’s

Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on top of Nokogiri. Loofah >= 2.2.0, < 2.19.1 uses recursion for sanitizing CDATA sections, making it susceptible to stack exhaustion and raising a SystemStackError exception. This may lead to a denial of service through CPU resource consumption. This issue is patched in version 2.19.1. Users who are unable to upgrade may be able to mitigate this vulnerability by limiting the length of the strings that are sanitized.

Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on top of Nokogiri. Loofah >= 2.1.0, < 2.19.1 is vulnerable to cross-site scripting via the image/svg+xml media type in data URIs. This issue is patched in version 2.19.1.

Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on top of Nokogiri. Loofah < 2.19.1 contains an inefficient regular expression that is susceptible to excessive backtracking when attempting to sanitize certain SVG attributes. This may lead to a denial of service through CPU resource consumption. This issue is patched in version 2.19.1.

Pi-Hole is a network-wide ad blocking via your own Linux hardware, AdminLTE is a Pi-hole Dashboard for stats and more. In case of an attack, the threat actor will obtain the ability to perform an unauthorized query for blocked domains on `queryads` endpoint. In the case of application, this vulnerability exists because of a lack of validation in code on a root server path: `/admin/scripts/pi-hole/phpqueryads.php.` Potential threat actor(s) are able to perform an unauthorized query search in blocked domain lists. This could lead to the disclosure for any victims' personal blacklists.

MeterSphere is a one-stop open source continuous testing platform. Versions prior to 2.4.1 are vulnerable to Path Injection in ApiTestCaseService::deleteBodyFiles which takes a user-controlled string id and passes it to ApiTestCaseService, which uses the user-provided value (testId) in new File(BODY_FILE_DIR + "/" + testId), being deleted later by file.delete(). By adding some camouflage parameters to the url, an attacker can target files on the server. The vulnerability has been fixed in v2.4.1.

A privilege escalation issue exists within the Amazon CloudWatch Agent for Windows, software for collecting metrics and logs from Amazon EC2 instances and on-premises servers, in versions up to and including v1.247354. When users trigger a repair of the Agent, a pop-up window opens with SYSTEM permissions. Users with administrative access to affected hosts may use this to create a new command prompt as NT AUTHORITYSYSTEM. To trigger this issue, the third party must be able to access the affected host and elevate their privileges such that they're able to trigger the agent repair process. They must also be able to install the tools required to trigger the issue. This issue does not affect the CloudWatch Agent for macOS or Linux. Agent users should upgrade to version 1.247355 of the CloudWatch Agent to address this issue. There is no recommended work around. Affected users must update the installed version of the CloudWatch Agent to address this issue.

cube-js is a headless business intelligence platform. In version 0.31.23 all authenticated Cube clients could bypass SQL row-level security and run arbitrary SQL via the newly introduced /v1/sql-runner endpoint. This issue has been resolved in version 0.31.24. Users are advised to either upgrade to 0.31.24 or to downgrade to 0.31.22. There are no known workarounds for this vulnerability.

The Post SMTP Mailer/Email Log WordPress plugin before 2.1.4 does not escape some of its settings before outputting them in the admins dashboard, allowing high privilege users to perform Cross-Site Scripting attacks against other users even when the unfiltered_html capability is disallowed.

Weave GitOps is a simple open source developer platform for people who want cloud native applications, without needing Kubernetes expertise. GitOps run has a local S3 bucket which it uses for synchronizing files that are later applied against a Kubernetes cluster. The communication between GitOps Run and the local S3 bucket is not encrypted. This allows privileged users or process to tap the local traffic to gain information permitting access to the s3 bucket. From that point, it would be possible to alter the bucket content, resulting in changes in the Kubernetes cluster's resources. There are no known workaround(s) for this vulnerability. This vulnerability has been fixed by commits ce2bbff and babd915. Users should upgrade to Weave GitOps version >= v0.12.0 released on 08/12/2022.

Weave GitOps is a simple open source developer platform for people who want cloud native applications, without needing Kubernetes expertise. A vulnerability in GitOps run could allow a local user or process to alter a Kubernetes cluster's resources. GitOps run has a local S3 bucket which it uses for synchronizing files that are later applied against a Kubernetes cluster. Its endpoint had no security controls to block unauthorized access, therefore allowing local users (and processes) on the same machine to see and alter the bucket content. By leveraging this vulnerability, an attacker could pick a workload of their choosing and inject it into the S3 bucket, which resulted in the successful deployment in the target cluster, without the need to provide any credentials to either the S3 bucket nor the target Kubernetes cluster. There are no known workarounds for this issue, please upgrade. This vulnerability has been fixed by commits 75268c4 and 966823b. Users should upgrade to Weave GitOps version >= v0.12.0 released on 08/12/2022. ### Workarounds There is no workaround for this vulnerability. ### References Disclosed by Paulo Gomes, Senior Software Engineer, Weaveworks. ### For more information If you have any questions or comments about this advisory: - Open an issue in [Weave GitOps repository](https://github.com/weaveworks/weave-gitops) - Email us at [support@weave.works](mailto:support@weave.works)
