**Descriptions****Configuration as Code Plugin failed to mask secrets in system log messages**

**SECURITY-1497 / CVE-2019-10367**  
**Severity (CVSS):** Medium  
**Affected plugin: configuration-as-code**  
**Description:**

Configuration as Code Plugin logs the changes it applies to the Jenkins system log. Secrets such as passwords should be masked (i.e. replaced with asterisks) in that log to prevent accidental disclosure. Configuration as Code Plugin inspects the type and looks for a field, getter, or constructor argument corresponding to the property, making the secret detection much more robust for the purpose of log message masking. This was implemented in the fix for SECURITY-1279 in the 2019-07-31 security advisory.

That fix was incomplete and did not cover a log message written to the logger io.jenkins.plugins.casc.impl.configurators.DataBoundConfigurator.

Configuration as Code Plugin now uses the same secret detection for these log messages.

As a workaround, administrators can configure the logging level of the logger io.jenkins.plugins.casc.impl.configurators.DataBoundConfigurator to a level that does not include these messages. Configuration as Code Plugin 1.25 and earlier logs these messages at the INFO level, Configuration as Code Plugin 1.26 logs them at FINE. See the logging documentation for details.

**CSRF vulnerability and missing permission check in JClouds Plugin allowed capturing credentials**

**SECURITY-1482 / CVE-2019-10368 (CSRF), CVE-2019-10369 (permission check)**  
**Severity (CVSS):** Medium  
**Affected plugin: jclouds-jenkins**  
**Description:**

JClouds Plugin did not perform permission checks on a method implementing form validation. This allowed users with Overall/Read access to Jenkins 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 did not require POST requests, resulting in a cross-site request forgery vulnerability.

This form validation method now requires POST requests and Overall/Administer permission.

**Mask Passwords Plugin shows plain text passwords in global configuration form fields**

**SECURITY-157 / CVE-2019-10370**  
**Severity (CVSS):** Low  
**Affected plugin: mask-passwords**  
**Description:**

Mask Passwords Plugin allows specifying passwords to be provided to builds in the global Jenkins configuration.

While the passwords are stored encrypted on disk, they are transmitted in plain text as part of the configuration form. This can result in exposure of the password through browser extensions, cross-site scripting vulnerabilities, and similar situations.

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

**HTTP session fixation vulnerability in GitLab Authentication Plugin**

**SECURITY-795 / CVE-2019-10371**  
**Severity (CVSS):** Medium  
**Affected plugin: gitlab-oauth**  
**Description:**

GitLab Authentication Plugin does not invalidate the previous session and create a new one upon successful login. This allows attackers able to control or obtain another user’s pre-login session ID to impersonate them.

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

**Open redirect vulnerability in GitLab Authentication Plugin**

**SECURITY-796 / CVE-2019-10372**  
**Severity (CVSS):** Medium  
**Affected plugin: gitlab-oauth**  
**Description:**

GitLab Authentication Plugin records the HTTP Referer header when the authentication process starts and redirects users to that URL when the user has finished logging in.

This implements an open redirect, allowing malicious sites to implement a phishing attack, with users expecting they have just logged in to Jenkins.

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

**Stored XSS vulnerability in Build Pipeline Plugin**

**SECURITY-879 / CVE-2019-10373**  
**Severity (CVSS):** Medium  
**Affected plugin: build-pipeline-plugin**  
**Description:**

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

**Stored XSS vulnerability in PegDown Formatter Plugin**

**SECURITY-142 / CVE-2019-10374**  
**Severity (CVSS):** Medium  
**Affected plugin: pegdown-formatter**  
**Description:**

PegDown Formatter Plugin uses the PegDown library to implement support for rendering Markdown formatted descriptions in Jenkins. It advertises disabling of HTML to prevent cross-site scripting (XSS) as a feature.

PegDown Formatter Plugin does not prevent the use of javascript: scheme in URLs for links. This results in an XSS vulnerability exploitable by users able to configure entities with descriptions or similar properties that are rendered by the configured markup formatter.

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

**Arbitrary file read vulnerability in File System SCM Plugin**

**SECURITY-569 / CVE-2019-10375**  
**Severity (CVSS):** Medium  
**Affected plugin: filesystem_scm**  
**Description:**

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

**Reflected XSS vulnerability in Wall Display Master Project Plugin**

**SECURITY-751 / CVE-2019-10376**  
**Severity (CVSS):** Medium  
**Affected plugin: jenkinswalldisplay**  
**Description:**

Wall Display Master Project Plugin does not properly escape the customTheme query parameter, resulting in a reflected cross-site scripting vulnerability.

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

**Avatar Plugin allows changing other users' avatars**

**SECURITY-1099 / CVE-2019-10377**  
**Severity (CVSS):** Medium  
**Affected plugin: avatar**  
**Description:**

Avatar Plugin does not implement a permission check for the HTTP URL used to replace user avatars. This allows any user with Overall/Read permission to change any other user’s avatar, in addition to their own.

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

**TestLink Plugin stores credentials in plain text**

**SECURITY-1428 / CVE-2019-10378**  
**Severity (CVSS):** Low  
**Affected plugin: testlink**  
**Description:**

TestLink Plugin stores credentials unencrypted in its global configuration file hudson.plugins.testlink.TestLinkBuilder.xml on the Jenkins controller. These credentials can be viewed by users with access to the Jenkins controller file system.

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

**Google Cloud Messaging Notification Plugin stores credentials in plain text**

**SECURITY-591 / CVE-2019-10379**  
**Severity (CVSS):** Low  
**Affected plugin: gcm-notification**  
**Description:**

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

**Script sandbox bypass vulnerability in Simple Travis Pipeline Runner Plugin**

**SECURITY-922 / CVE-2019-10380**  
**Severity (CVSS):** High  
**Affected plugin: simple-travis-runner**  
**Description:**

Simple Travis Pipeline Runner Plugin defines a custom list of pre-approved signatures for scripts protected by the Script Security sandbox.

This custom list of pre-approved signatures allows the use of methods that can be used to bypass Script Security sandbox protection. This results in arbitrary code execution on any Jenkins instance with this plugin installed.

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

**Codefresh Integration Plugin globally and unconditionally disables SSL/TLS certificate validation**

**SECURITY-931 / CVE-2019-10381**  
**Severity (CVSS):** Medium

**CSRF vulnerability and missing permission check in XL TestView Plugin allow capturing credentials**

**SECURITY-1008 / CVE-2019-10386 (CSRF), CVE-2019-10387 (permission check)**  
**Severity (CVSS):** Medium  
**Affected plugin: xltestview-plugin**  
**Description:**

XL TestView Plugin does not perform permission checks on a method implementing form validation. This allows users with Overall/Read access to Jenkins 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 vulnerability.

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

**CSRF vulnerability and missing permission check in Relution Enterprise Appstore Publisher Plugin allow SSRF**

**SECURITY-1053 / CVE-2019-10388 (CSRF), CVE-2019-10389 (permission check)**  
**Severity (CVSS):** Medium  
**Affected plugin: relution-publisher**  
**Description:**

A missing permission check in a form validation method in Relution Enterprise Appstore Publisher Plugin allows users with Overall/Read permission to initiate a connection test to an attacker-specified URL using attacker-specified credentials and attacker-specified HTTP proxy configuration.

While attempting to use Google Security Team's CVE-2017-14491 in dnsmasq versions <2.78, I found a new exploit present
in dnsmasq <2.76. In this case, an attacker controlled dns server to could send a response greater than 4096 bytes. 
Since this response is truncated at 4096 bytes, part of the packet is left off, a "tail." When examing the source code,
I found that dnsmasq in do\_doctor() in rfc1035.c iterates through each answer record. In this function, the pointer to
the packet read is incremented by 4 bytes to bypass the time to live section of the answer. Since a large packet is 
truncated at 4096 bytes, this pointer can read further beyond the memory allocated to it on the heap, potentially 
causing a bad read leading to a crash and denial of service. 

The proof-of-concept (poc) provided are heavily based off of the research done by Google's security team in 2017.

CVE-2019-14513: GitHub - Slovejoy/dnsmasq-pre2.76: vulnerability assessment for early versions of dnsmasq

Jenkins Configuration as Code Plugin 1.24 and earlier did not properly apply masking to values expected to be hidden when logging the configuration being applied.

This advisory announces vulnerabilities in the following Jenkins deliverables:

*   Amazon EC2 Plugin
*   Configuration as Code Plugin
*   Google Kubernetes Engine Plugin
*   Maven Integration Plugin
*   Maven Release Plug-in Plugin
*   Pipeline: Deprecated Groovy Libraries Plugin
*   Script Security Plugin
*   Skytap Cloud CI Plugin

**Descriptions****Sandbox bypass through type casts in Script Security Plugin**

**SECURITY-1465 (1) / CVE-2019-10355**  
**Severity (CVSS):** High  
**Affected plugin: script-security**  
**Description:**

Sandbox protection in Script Security Plugin could be circumvented by casting crafted objects to other types. This allowed attackers able to specify sandboxed scripts to invoke constructors that weren’t approved.

Additionally, this could be used to read arbitrary files on the Jenkins controller.

Casting collections to other types as an alternative syntax for constructor invocation is now only allowed when the collection type is defined in java.util, and prohibited otherwise. Casting files and enums to arrays is now intercepted by the sandbox and treated as the invocation of an equivalent method.

**Sandbox bypass through method pointer expressions in Script Security Plugin**

**SECURITY-1465 (2) / CVE-2019-10356**  
**Severity (CVSS):** High  
**Affected plugin: script-security**  
**Description:**

Sandbox protection in Script Security Plugin could be circumvented through crafted subexpressions used as arguments to method pointer expressions. This allowed attackers able to specify sandboxed scripts to execute arbitrary code in the context of the Jenkins controller JVM.

Method pointer subexpressions are now subject to sandbox protection.

**Missing permission check in Pipeline: Deprecated Groovy Libraries Plugin**

**SECURITY-1422 / CVE-2019-10357**  
**Severity (CVSS):** Medium  
**Affected plugin: workflow-cps-global-lib**  
**Description:**

Pipeline: Deprecated Groovy Libraries Plugin provides form validation to determine whether the revision (e.g. commit, tag, or branch name) specified for a global library exists in the repository. This form validation method lacked a permission check, allowing attackers with Overall/Read access to determine whether an attacker-specified revision exists in an SCM repository configured for use in an existing shared library.

Pipeline: Deprecated Groovy Libraries Plugin now performs the appropriate permission check.

**Maven Integration Plugin did not mask sensitive values in module build logs**

**SECURITY-713 / CVE-2019-10358**  
**Severity (CVSS):** Medium  
**Affected plugin: maven-plugin**  
**Description:**

Maven Integration Plugin did not apply build log decorators from the Build Environment configuration to module builds. This could prevent sensitive content in module build logs from being masked.

Maven Integration Plugin now applies build log decorators from the Build Environment configuration to module builds.

**CSRF vulnerability in Maven Release Plug-in Plugin**

**SECURITY-1098 / CVE-2019-10359**  
**Severity (CVSS):** Medium  
**Affected plugin: m2release**  
**Description:**

Maven Release Plug-in Plugin did not require that requests sent to the endpoint used to initiate the release process use POST. This resulted in a cross-site request forgery vulnerability that allows attackers to perform releases.

Maven Release Plug-in Plugin now requires that these requests be sent via POST.

**Stored XSS vulnerability in Maven Release Plug-in Plugin**

**SECURITY-1184 / CVE-2019-10360**  
**Severity (CVSS):** Medium  
**Affected plugin: m2release**  
**Description:**

Maven Release Plug-in Plugin did not properly escape variables in multiple views, resulting in a stored cross-site scripting vulnerability.

Variables on affected views are now escaped.

**Maven Release Plug-in Plugin stored credentials in plain text**

**SECURITY-1435 / CVE-2019-10361**  
**Severity (CVSS):** Low  
**Affected plugin: m2release**  
**Description:**

Maven Release Plug-in Plugin stored credentials unencrypted in its global configuration file org.jvnet.hudson.plugins.m2release.M2ReleaseBuildWrapper.xml on the Jenkins controller. These credentials could be viewed by users with access to the Jenkins controller file system.

Maven Release Plug-in Plugin now stores credentials encrypted.

**Configuration as Code Plugin failed to mask secrets in system log messages**

**SECURITY-1279 / CVE-2019-10343**  
**Severity (CVSS):** Medium  
**Affected plugin: configuration-as-code**  
**Description:**

Configuration as Code Plugin logs the changes it applies to the Jenkins system log. Secrets such as passwords should be masked (i.e. replaced with asterisks) in that log to prevent accidental disclosure.

Between Configuration as Code Plugin 0.8-alpha and 1.0, log messages contained values if the values were specified using properties in the YAML file (SECURITY-929).

Since Configuration as Code Plugin 1.1, log messages in Configuration as Code Plugin instead mask values of type Secret, which is used in Jenkins to store the values encrypted on disk. This did not work in many instances, as plugins could use the Secret type to store credentials encrypted on disk while not having the Secret type appear in their Java API.

Configuration as Code Plugin now inspects the type and looks for a field, getter, or constructor argument corresponding to the property, making the secret detection much more robust for the purpose of log message masking.

As a workaround, administrators can configure the logging level of the logger io.jenkins.plugins.casc.Attribute to a level that does not include INFO messages. See the logging documentation for details.

**Configuration as Code Plugin allowed users without Overall/Administer permission to access documentation**

**SECURITY-1290 / CVE-2019-10344**  
**Severity (CVSS):** Medium  
**Affected plugin: configuration-as-code**  
**Description:**

Configuration as Code Plugin provides a generated schema and reference documentation for the configuration options supported on the current Jenkins instance. These URLs did not perform additional permission checks, resulting in their content being available to users with Overall/Read access. This included detailed information about installed plugins that may not be available otherwise.

Access to these URLs is now restricted to users with Overall/Administer permission.

**Configuration as Code Plugin did not mask proxy credentials**

**SECURITY-1303 / CVE-2019-10345**  
**Severity (CVSS):** Low  
**Affected plugin: configuration-as-code**  
**Description:**

Configuration as Code Plugin provides a custom configurator for the Jenkins proxy configuration.

This feature did not mask the password for logging or encrypt it in the export.

Configuration as Code Plugin 1.20 and newer mask the Jenkins proxy password when logged and only store it encrypted in the export.

**Configuration as Code Plugin evaluated variable references when importing a previously exported configuration**

**SECURITY-1446 / CVE-2019-10362**  
**Severity (CVSS):** Medium  
**Affected plugin: configuration-as-code**  
**Description:**

Configuration as Code Plugin allows exporting the live Jenkins configuration, as well as importing and applying a configuration provided in the same format. One of the features of the import is that it allows specifying variable references (e.g. ${VARIABLE_NAME}) in the configuration YAML file. These will be replaced by the value of the corresponding environment variable (or other source of secrets) during import (interpolation). If such a value should not be interpolated, the escape character ^ can be used before (e.g. ^${VARIABLE_NAME}).

Exporting did not add ^ escape characters to exported strings, such as various entity descriptions. This allowed attackers with permission to configure certain entities, such as credentials or agents, to specify crafted descriptions containing variable references. These would be replaced by the corresponding environment variable’s value during a subsequent import.

The export now adds ^ escape characters to exported strings as needed to prevent them from being interpolated during import. Previously exported configurations may require manual cleanup by Jenkins admins before being imported.

**Configuration as Code Plugin exported secret values in plain text**

**SECURITY-1458 / CVE-2019-10363**  
**Severity (CVSS):** Medium  
**Affected plugin: configuration-as-code**  
**Description:**

Configuration as Code Plugin allows to export the current Jenkins configuration as a YAML file. Secrets such as passwords should be exported in their encrypted form to prevent accidental disclosure.

Configuration as Code Plugin did not reliably detect which values in the exported YAML file need to be considered sensitive (e.g. credentials and other secrets), as plugins could use the Secret type to store credentials encrypted on disk while not having the Secret type appear in their Java API. This resulted in credentials being exported in plain text in some cases.

Configuration as Code Plugin now inspects the type and looks for a field, getter, or constructor argument corresponding to the property, making the secret detection much more robust for the purpose of exporting encrypted secrets.

**Amazon EC2 Plugin leaked beginning of private key in system log**

**SECURITY-673 / CVE-2019-10364**  
**Severity (CVSS):** Medium  
**Affected plugin: ec2**  
**Description:**

Amazon EC2 Plugin printed a log message that contained the beginning of the private key to the Jenkins system log.

The log message no longer includes the beginning of the private key.

**Google Kubernetes Engine Plugin stored temporary secret in a user accessible location**

**SECURITY-1345 / CVE-2019-10365**  
**Severity (CVSS):** Medium  
**Affected plugin: google-kubernetes-engine**  
**Description:**

Google Kubernetes Engine Plugin created a temporary file named .kube…config containing a temporary access token in the project workspace. This allowed the file to be accessed via workspace browsers, or accidentally archived, disclosing the token.

This temporary file is now created outside the regular project workspace.

**Skytap Cloud CI Plugin stored credentials in plain text**

**SECURITY-1429 / CVE-2019-10366**  
**Severity (CVSS):** Medium  
**Affected plugin: skytap**  
**Description:**

Skytap Cloud CI Plugin stored credentials unencrypted in job config.xml files on the Jenkins controller. These credentials could be viewed by users with Extended Read permission, or access to the Jenkins controller file system.

Skytap Cloud CI Plugin now stores credentials encrypted.
