This vulnerability allows attackers to copy an item, which could potentially automatically approve unsandboxed scripts and allow the execution of unsafe scripts. An improvement added in Script Security Plugin 1265.va_fb_290b_4b_d34 and 1251.1253.v4e638b_e3b_221 prevents automatic approval of unsandboxed scripts when administrators copy jobs, significantly reducing the impact of this vulnerability. Folders Plugin 6.848.ve3b_fd7839a_81 requires POST requests for the affected HTTP endpoint. CSRF vulnerability in Folders Plugin SECURITY-3105 / CVE-2023-40337 Severity (CVSS): Medium Affected plugin: cloudbees-folder Description: Folders Plugin 6.846.v23698686f0f6 and earlier does not require POST requests for an HTTP endpoint, resulting in a cross-site request forgery (CSRF) vulnerability. This vulnerability allows attackers to copy a view inside a folder. Folders Plugin 6.848.ve3b_fd7839a_81 requires POST requests for the affected HTTP endpoint. Information disclosure in Folders Plugin SECURITY-3109 / CVE-2023-40338 Severity (CVSS): Medium Affected plugin: cloudbees-folder Description: Folders Plugin displays an error message when attempting to access the Scan Organization Folder Log if no logs are available. In Folders Plugin 6.846.v23698686f0f6 and earlier, this error message includes the absolute path of a log file, exposing information about the Jenkins controller file system. Folders Plugin 6.848.ve3b_fd7839a_81 does not display the absolute path of a log file in the error message. Improper masking of credentials in Config File Provider Plugin SECURITY-3090 / CVE-2023-40339 Severity (CVSS): Medium Affected plugin: config-file-provider Description: Config File Provider Plugin 952.va_544a_6234b_46 and earlier does not mask (i.e., replace with asterisks) credentials specified in configuration files when they’re written to the build log. Config File Provider Plugin 953.v0432a_802e4d2 masks credentials configured in configuration files if they appear in the build log. Improper masking of credentials in NodeJS Plugin SECURITY-3196 / CVE-2023-40340 Severity (CVSS): Medium Affected plugin: nodejs Description: NodeJS Plugin integrates with Config File Provider Plugin to specify custom NPM settings, including credentials for authentication, in a Npm config file. NodeJS Plugin 1.6.0 and earlier does not properly mask (i.e., replace with asterisks) credentials specified in the Npm config file in Pipeline build logs. NodeJS Plugin 1.6.0.1 masks credentials specified in the Npm config file in Pipeline build logs. CSRF vulnerability in Blue Ocean Plugin allows capturing credentials SECURITY-3116 / CVE-2023-40341 Severity (CVSS): Medium Affected plugin: blueocean Description: Blue Ocean Plugin 1.27.5 and earlier does not require POST requests for an HTTP endpoint, resulting in a cross-site request forgery (CSRF) vulnerability. This vulnerability allows attackers to connect to an attacker-specified URL, capturing GitHub credentials associated with an attacker-specified job. This issue is due to an incomplete fix of SECURITY-2502. Blue Ocean Plugin 1.27.5.1 uses the configured SCM URL, instead of a user-specified URL provided as a parameter to the HTTP endpoint. CSRF vulnerability and missing permission checks in Fortify Plugin allow capturing credentials SECURITY-3115 / CVE-2023-4301 (CSRF), CVE-2023-4302 (missing permission check) Severity (CVSS): Medium Affected plugin: fortify Description: Fortify Plugin 22.1.38 and earlier does not perform permission checks in several HTTP endpoints. This allows attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins. Additionally, these HTTP endpoints do not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability. Fortify Plugin 22.2.39 requires POST requests and the appropriate permissions for the affected HTTP endpoints. HTML injection vulnerability in Fortify Plugin SECURITY-3140 / CVE-2023-4303 Severity (CVSS): Medium Affected plugin: fortify Description: Fortify Plugin 22.1.38 and earlier does not escape the error message for a form validation method. This results in an HTML injection vulnerability. Since Jenkins 2.275 and LTS 2.263.2, a security hardening for form validation responses prevents JavaScript execution, so no scripts can be injected. Fortify Plugin 22.2.39 removes HTML tags from the error message. Stored XSS vulnerability in Flaky Test Handler Plugin SECURITY-3223 / CVE-2023-40342 Severity (CVSS): High Affected plugin: flaky-test-handler Description: Flaky Test Handler Plugin 1.2.2 and earlier does not escape JUnit test contents when showing them on the Jenkins UI. This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to control JUnit report file contents. Flaky Test Handler Plugin 1.2.3 escapes JUnit test contents when showing them on the Jenkins UI. Non-constant time token comparison in Tuleap Authentication Plugin SECURITY-3229 / CVE-2023-40343 Severity (CVSS): Low Affected plugin: tuleap-oauth Description: Tuleap Authentication Plugin 1.1.20 and earlier does not use a constant-time comparison when checking whether two authentication tokens are equal. This could potentially allow attackers to use statistical methods to obtain a valid authentication token. Tuleap Authentication Plugin 1.1.21 uses a constant-time comparison when validating authentication tokens. Missing permission check in Delphix Plugin allows enumerating credentials IDs SECURITY-3214 (1) / CVE-2023-40344 Severity (CVSS): Medium Affected plugin: delphix Description: Delphix Plugin 3.0.2 and earlier does not perform a permission check in an HTTP endpoint. 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. An enumeration of credentials IDs in Delphix Plugin 3.0.3 requires the appropriate permissions. Exposure of system-scoped credentials in Delphix Plugin SECURITY-3214 (2) / CVE-2023-40345 Severity (CVSS): Medium Affected plugin: delphix Description: Delphix Plugin 3.0.2 and earlier does not set the appropriate context for credentials lookup, allowing the use of System-scoped credentials otherwise reserved for the global configuration. This allows attackers with Overall/Read permission to access and capture credentials they are not entitled to. Delphix Plugin 3.0.3 defines the appropriate context for credentials lookup. Stored XSS vulnerability in Shortcut Job Plugin SECURITY-3071 / CVE-2023-40346 Severity (CVSS): High Affected plugin: shortcut-job Description: Shortcut Job Plugin 0.4 and earlier does not escape the shortcut redirection URL. This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to configure shortcut jobs. Shortcut Job Plugin 0.5 escapes the shortcut redirection URL.

Unsafe default behavior and information disclosure in Gogs Plugin webhook SECURITY-2894 / CVE-2023-40348 (information disclosure), CVE-2023-40349 (insecure default) Severity (CVSS): Medium Affected plugin: gogs-webhook Description: Gogs Plugin provides a webhook endpoint at /gogs-webhook that can be used to trigger builds of jobs. In Gogs Plugin 1.0.15 and earlier, an option to specify a Gogs secret for this webhook is provided, but not enabled by default. This allows unauthenticated attackers to trigger builds of jobs corresponding to the attacker-specified job name. Additionally, the output of the webhook endpoint includes whether a job corresponding to the attacker-specified job name exists, even if the attacker has no permission to access it. As of publication of this advisory, there is no fix. Learn why we announce this. Stored XSS vulnerability in Docker Swarm Plugin SECURITY-2811 / CVE-2023-40350 Severity (CVSS): High Affected plugin: docker-swarm Description: Docker Swarm Plugin processes Docker responses to generate the Docker Swarm Dashboard view. Docker Swarm Plugin 1.11 and earlier does not escape values returned from Docker before inserting them into the Docker Swarm Dashboard view.

Jenkins 2.415 and earlier, LTS 2.401.2 and earlier does not sanitize or properly encode URLs of these hyperlinks in build logs. This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to control build log contents. Jenkins 2.416, LTS 2.401.3 encodes URLs of affected hyperlink annotations in build logs. Incorrect control flow in Gradle Plugin breaks credentials masking in the build log SECURITY-3208 / CVE-2023-39152 Severity (CVSS): Medium Affected plugin: gradle Description: Gradle Plugin 2.8 improperly invokes APIs available only on the controller from an agent when setting up build log annotations, causing an exception. As a result, credentials may not be masked (i.e., replaced with asterisks) in the build log in some circumstances. Gradle Plugin 2.8.1 improves the control flow and handles the exception, so that credentials masking is not affected. An improvement in Pipeline: API 1232.v1679fa_2f0f76 prevents issues like this from affecting credentials masking in the future. As of the publication of this advisory, the Jenkins security team is not aware of other plugins with a similar issue. CSRF vulnerability in GitLab Authentication Plugin SECURITY-2696 / CVE-2023-39153 Severity (CVSS): Medium Affected plugin: gitlab-oauth Description: GitLab Authentication Plugin 1.17.1 and earlier does not implement a state parameter in its OAuth flow, a unique and non-guessable value associated with each authentication request. This vulnerability allows attackers to trick users into logging in to the attacker’s account. GitLab Authentication Plugin 1.18 implements a state parameter in its OAuth flow. CSRF vulnerability and missing permission check in ServiceNow DevOps Plugin allow capturing credentials SECURITY-3129 / CVE-2023-3414 (CSRF), CVE-2023-3442 (missing permission check) Severity (CVSS): Medium Affected plugin: servicenow-devops Description: ServiceNow DevOps Plugin 1.38.0 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 attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins. Additionally, this form validation method does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability. ServiceNow DevOps Plugin 1.38.1 requires POST requests and Overall/Administer permission for the affected form validation method. Incorrect permission checks in Qualys Web App Scanning Connector Plugin allow capturing credentials SECURITY-3012 / CVE-2023-39154 Severity (CVSS): Medium Affected plugin: qualys-was Description: Qualys Web App Scanning Connector Plugin 2.0.10 and earlier does not correctly perform permission checks in several HTTP endpoints. This allows attackers with global Item/Configure permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins. Qualys Web App Scanning Connector Plugin 2.0.11 requires the appropriate permissions for the affected HTTP endpoints. Secret displayed without masking by Chef Identity Plugin SECURITY-3192 / CVE-2023-39155 Severity (CVSS): Low Affected plugin: chef-identity Description: Chef Identity Plugin stores the user.pem key in its global configuration file io.chef.jenkins.ChefIdentityBuildWrapper.xml on the Jenkins controller as part of its configuration. While this key is stored encrypted on disk, in Chef Identity Plugin 2.0.3 and earlier the global configuration form does not mask the user.pem key form field, increasing the potential for attackers to observe and capture it.
