Descriptions****Sensitive parameter values captured in build metadata files by Parameterized Trigger Plugin

SECURITY-2185 / CVE-2022-27195

Parameterized Trigger Plugin 2.43 and earlier captures environment variables passed to builds triggered using Parameterized Trigger Plugin, including password parameter values, in their build.xml files. These values are stored unencrypted and can be viewed by users with access to the Jenkins controller file system.

Parameterized Trigger Plugin 2.43.1 does not store captured environment variables in build.xml files.

Note

Existing build.xml files are not automatically updated to remove captured environment variables. They need to be manually cleaned up. To help with this, the plugin will report environment variables stored in build.xml as unloadable data in the Old Data Monitor, that allows discarding this data. Build records are only loaded from disk when needed however, so some builds stored in Jenkins may not immediately appear there.

Stored XSS vulnerability in Favorite Plugin

SECURITY-2557 / CVE-2022-27196

Favorite Plugin 2.4.0 and earlier does not escape the names of jobs in the favorite column.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Configure or Item/Create permissions.

Favorite Plugin 2.4.1 escapes the names of jobs in the favorite column.

Stored XSS vulnerability in Dashboard View Plugin

SECURITY-2559 / CVE-2022-27197

Dashboard View Plugin 2.18 and earlier does not perform URL validation for the Iframe Portlet’s Iframe source URL.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to configure views.

Dashboard View Plugin 2.18.1 performs URL validation for the Iframe Portlet’s Iframe source URL.

Additionally, Dashboard View Plugin 2.18.1 sets the sandbox attribute for the iframe to restrict the included page.

Note

In case of problems, the Java system property hudson.plugins.view.dashboard.core.IframePortlet.sandboxAttributeValue can be used to customize the sandbox attribute value. The Java system property hudson.plugins.view.dashboard.core.IframePortlet.doNotUseSandbox can be used to disable the sandbox completely.

CSRF vulnerability and missing permission checks in CloudBees AWS Credentials Plugin

SECURITY-2351 / CVE-2022-27198 (CSRF), CVE-2022-27199 (permission check)

CloudBees AWS Credentials Plugin 189.v3551d5642995 and earlier does not perform a permission check in a method implementing form validation.

This allows attackers with Overall/Read permission to connect to an AWS service using an attacker-specified token.

Additionally, this form validation method does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.

This form validation method requires POST requests and Overall/Administer permission in CloudBees AWS Credentials Plugin 191.vcb_f183ce58b_9.

Stored XSS vulnerability in Folder-based Authorization Strategy Plugin

SECURITY-2646 / CVE-2022-27200

Folder-based Authorization Strategy Plugin 1.3 and earlier does not escape the names of roles shown on the configuration form.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Overall/Administer permission.

Folder-based Authorization Strategy Plugin 1.4 escapes the names of roles shown on the configuration form.

Agent-to-controller security bypass in Semantic Versioning Plugin

SECURITY-2124 / CVE-2022-27201

Semantic Versioning Plugin defines a controller/agent message that processes a given file as XML and returns version information. The XML parser is not configured to prevent XML external entity (XXE) attacks, which is only a problem if XML documents are parsed on the Jenkins controller.

Semantic Versioning Plugin 1.13 and earlier does not restrict execution of the controller/agent message to agents, and implements no limitations about the file path that can be parsed. This allows attackers able to control agent processes to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

Note

This vulnerability is only exploitable in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier. See the LTS upgrade guide.

Semantic Versioning Plugin 1.14 does not allow the affected controller/agent message to be submitted by agents for execution on the controller.

Stored XSS vulnerability in Extended Choice Parameter Plugin

SECURITY-2232 / CVE-2022-27202

Extended Choice Parameter Plugin 346.vd87693c5a_86c and earlier does not escape the value and description of Extended Choice Parameters with parameter type ‘Radio Buttons’ or 'Check Boxes’.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Configure permission.

As of publication of this advisory, there is no fix.

Arbitrary JSON and property file read vulnerability in Extended Choice Parameter Plugin

SECURITY-1351 / CVE-2022-27203

Extended Choice Parameter Plugin 346.vd87693c5a_86c and earlier allows attackers with Item/Configure permission to read values from arbitrary JSON and Java properties files on the Jenkins controller.

CSRF vulnerability and missing permission checks in Extended Choice Parameter Plugin allow SSRF

SECURITY-1350 / CVE-2022-27204 (CSRF), CVE-2022-27205 (permission check)

Extended Choice Parameter Plugin 346.vd87693c5a_86c and earlier does not perform a permission check on form validation methods. This allows attackers with Overall/Read permission to connect to an attacker-specified URL.

Additionally, these form validation methods do not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.

As of publication of this advisory, there is no fix.

Client Secret stored in plain text by GitLab Authentication Plugin

SECURITY-1891 / CVE-2022-27206

GitLab Authentication Plugin 1.13 and earlier stores the GitLab client secret unencrypted in the global config.xml file on the Jenkins controller as part of its configuration.

This client secret can be viewed by users with access to the Jenkins controller file system.

As of publication of this advisory, there is no fix.

Stored XSS vulnerability in global-build-stats Plugin

SECURITY-1886 / CVE-2022-27207

global-build-stats Plugin 1.5 and earlier does not escape multiple fields in the chart configuration on the ‘Global Build Stats’ page.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Overall/Administer permission.

As of publication of this advisory, there is no fix.

Arbitrary file read vulnerability in Kubernetes Continuous Deploy Plugin

SECURITY-2096 / CVE-2022-27208

Kubernetes Continuous Deploy Plugin contributes the 'Kubernetes configuration (kubeconfig)' credential type.

Kubernetes Continuous Deploy Plugin 2.3.1 and earlier allows users with Credentials/Create or Credentials/Update permission to read arbitrary files on the Jenkins controller by defining a ‘From a file on the Jenkins master’ Kubeconfig source for such a credential.

As of publication of this advisory, there is no fix.

Missing permission checks in Kubernetes Continuous Deploy Plugin allow enumerating credentials IDs

SECURITY-2636 / CVE-2022-27209

Kubernetes Continuous Deploy Plugin 2.3.1 and earlier does not perform permission checks in several HTTP endpoints.

This allows attackers with Overall/Read permission to enumerate credentials IDs of credentials stored in Jenkins. Those can be used as part of an attack to capture the credentials using another vulnerability.

As of publication of this advisory, there is no fix.

CSRF vulnerability and missing permission checks in Kubernetes Continuous Deploy Plugin allow capturing credentials

SECURITY-2681 / CVE-2022-27210 (CSRF), CVE-2022-27211 (permission check)

Kubernetes Continuous Deploy Plugin 2.3.1 and earlier does not perform a permission check in an HTTP endpoint.

This allows attackers with Overall/Read permission to connect to an attacker-specified SSH server using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

Additionally, this endpoint does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.

As of publication of this advisory, there is no fix.

Stored XSS vulnerability in List Git Branches Parameter Plugin

SECURITY-2167 / CVE-2022-27212
