Jenkins Security Advisory 2022-03-29

Bitbucket Server Integration Plugin 2.0.0 through 3.1.0 (inclusive) does not limit URL schemes for callback URLs on OAuth consumers.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to create BitBucket Server consumers.

Bitbucket Server Integration Plugin 3.2.0 limits allowed URL schemes to prevent creation of consumers with javascript: URL scheme.

Bitbucket Server Integration Plugin 3.1.0 and earlier does not perform permission checks in several HTTP endpoints.

This allows attackers with Overall/Read permission to create, view, and delete BitBucket Server consumers.

Bitbucket Server Integration Plugin 3.2.0 requires Overall/System Read permission to view BitBucket Server consumers, and Overall/Administer permission to modify them.

instant-messaging Plugin provides a framework for plugins integrating Jenkins with instant messaging services.

instant-messaging Plugin 1.41 and earlier stores passwords for group chats unencrypted in the global configuration file of plugins based on instant-messaging Plugin on the Jenkins controller.

These passwords can be viewed by users with access to the Jenkins controller file system.

instant-messaging Plugin 1.42 stores passwords for group chats encrypted once the integrating plugin’s configuration is saved again.

JiraTestResultReporter Plugin 165.v817928553942 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.

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 JiraTestResultReporter Plugin 166.v0cc6208295b5.

RocketChat Notifier Plugin 1.4.10 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 username and password.

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

RocketChat Notifier Plugin 1.5.0 requires POST requests and Overall/Administer permission for the affected form validation method.

Flaky Test Handler Plugin 1.2.1 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

This allows attackers with Item/Configure permission to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

Flaky Test Handler Plugin 1.2.2 disables external entity resolution for its XML parser.

Proxmox Plugin 0.5.0 and earlier stores the Proxmox Datacenter password unencrypted in the global config.xml file on the Jenkins controller as part of its configuration.

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

Proxmox Plugin 0.6.0 stores the Proxmox Datacenter password encrypted once its configuration is saved again.

Proxmox Plugin 0.6.0 and earlier disables SSL/TLS certificate validation for the entire Jenkins controller JVM when configured to ignore SSL/TLS issues.

Proxmox Plugin 0.7.0 no longer disables SSL/TLS certificate validation for the entire Jenkins controller JVM.

Proxmox Plugin 0.7.0 and earlier does not perform permission checks in several HTTP endpoints.

This allows attackers with Overall/Read permission to:

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

Proxmox Plugin 0.7.1 requires POST requests and Overall/Administer permission for the affected HTTP endpoints.

Continuous Integration with Toad Edge Plugin 2.3 and earlier uses a patched fork of an old version of the file browser for workspaces, archived artifacts, and userContent/ from Jenkins core (DirectoryBrowserSupport) to serve reports.

This fork removes the Content-Security-Policy header functionality introduced for SECURITY-95.

This results in a stored cross-site scripting (XSS) exploitable by attackers with Item/Configure permission or otherwise able to control report contents.

Continuous Integration with Toad Edge Plugin 2.4 uses the built-in Jenkins file browser to serve reports.

Continuous Integration with Toad Edge Plugin 2.3 and earlier allows attackers with Item/Configure permission to read arbitrary files on the Jenkins controller by specifying an input folder on the Jenkins controller as a parameter to its build steps.

Continuous Integration with Toad Edge Plugin 2.4 only allows copying files from the node the build is executing on.

Continuous Integration with Toad Edge Plugin 2.3 and earlier does not perform a permission check in a method implementing form validation.

This allows attackers with Overall/Read permission to check for the existence of an attacker-specified file path on the Jenkins controller file system.

Continuous Integration with Toad Edge Plugin 2.4 requires Overall/Administer permission for the affected form validation method.

Continuous Integration with Toad Edge Plugin 2.3 and earlier uses a patched fork of an old version of the file browser for workspaces, archived artifacts, and userContent/ from Jenkins core (DirectoryBrowserSupport) to serve reports.

The fork did not receive the fix for SECURITY-2481 in Jenkins 2.315 and LTS 2.303.2.

This results in a path traversal vulnerability allowing attackers with Item/Read permission to obtain the contents of arbitrary files on Windows controllers.

Continuous Integration with Toad Edge Plugin 2.4 uses the built-in Jenkins file browser to serve reports, inheriting the fix in Jenkins core if running on a recent enough version.

Job and Node ownership Plugin 0.13.0 and earlier does not escape the names of secondary owners.

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. Learn why we announce this.

Job and Node ownership Plugin 0.13.0 and earlier does not perform a permission check in several HTTP endpoints.

This allows attackers with Item/Read permission to change the owners and item-specific permissions of a job.

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. Learn why we announce this.

Job and Node ownership Plugin 0.13.0 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 restore the default ownership of a job.

As of publication of this advisory, there is no fix. Learn why we announce this.

SiteMonitor Plugin 0.6 and earlier does not escape URLs of sites to monitor in tooltips.

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. Learn why we announce this.

Coverage/Complexity Scatter Plot Plugin 1.1.1 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

This allows attackers able to control the input files for the 'Public Coverage / Complexity Scatter Plot' post-build step to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

As of publication of this advisory, there is no fix. Learn why we announce this.

Pipeline: Phoenix AutoTest Plugin 1.3 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

This allows attackers able to control the input files for the readXml or writeXml build step to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

As of publication of this advisory, there is no fix. Learn why we announce this.

Pipeline: Phoenix AutoTest Plugin 1.3 and earlier implements a Pipeline step (copy) to copy files from the running build’s directory on the Jenkins controller to an agent without sanitizing the path specified.

This allows attackers with Item/Configure permission to copy arbitrary files and directories from the Jenkins controller to the agent workspace.

As of publication of this advisory, there is no fix. Learn why we announce this.

Pipeline: Phoenix AutoTest Plugin 1.3 and earlier implements a Pipeline step (ftp) to upload files to an FTP server without limiting the source directory.

This allows attackers with Item/Configure permission to upload arbitrary files from the Jenkins controller via FTP to an attacker-specified FTP server.

As of publication of this advisory, there is no fix. Learn why we announce this.

Pipeline: Phoenix AutoTest Plugin 1.3 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. Learn why we announce this.

Tests Selector Plugin 1.3.3 and earlier does not escape the Properties File Path option for Choosing Tests parameters.

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. Learn why we announce this.

Tests Selector Plugin 1.3.3 and earlier allows users with Item/Configure permission to read arbitrary files on the Jenkins controller using the Choosing Tests parameter.
