SECURITY-1754 / CVE-2020-2134 (constructors) & CVE-2020-2135 (GroovyInterceptable)
Sandbox protection in Script Security Plugin 1.70 and earlier can be
circumvented through:
* Crafted constructor calls and bodies
* Crafted method calls on objects that implement `GroovyInterceptable`
This allows attackers able to specify and run sandboxed scripts to execute
arbitrary code in the context of the Jenkins master JVM.
SECURITY-1723 / CVE-2020-2136
Git Plugin 4.2.0 and earlier does not escape the error message for the
repository URL for Microsoft TFS field form validation.
This results in a stored cross-site scripting vulnerability that can be
exploited by users with Job/Configure permission.
SECURITY-1784 / CVE-2020-2137
Timestamper Plugin 1.11.1 and earlier does not escape or sanitize the HTML
formatting used to display the timestamps in console output for builds.
This results in a stored cross-site scripting vulnerability that can be
exploited by users with Overall/Administer permission.
SECURITY-1700 / CVE-2020-2138
Cobertura Plugin 1.15 and earlier does not configure its XML parser to
prevent XML external entity (XXE) attacks.
This allows a user able to control the input files for the 'Publish
Cobertura Coverage Report' post-build step to have Jenkins parse a crafted
file that uses external entities for extraction of secrets from the Jenkins
master or server-side request forgery.
SECURITY-1668 / CVE-2020-2139
Cobertura Plugin 1.15 and earlier does not validate file paths from the XML
file it parses.
This allows attackers able to control the coverage report content to
overwrite any file on the Jenkins master file system.
SECURITY-1722 / CVE-2020-2140
Audit Trail Plugin 3.2 and earlier does not escape the error message for
the URL Patterns field form validation.
This results in a reflected cross-site scripting vulnerability that can
also be exploited similar to a stored cross-site scripting vulnerability by
users with Overall/Administer permission.
SECURITY-1765 / CVE-2020-2141 (CSRF) & CVE-2020-2142 (missing permission check)
P4 Plugin 1.10.10 and earlier does not perform permission checks in several
HTTP endpoints. This allows users with Overall/Read access to trigger
builds or add labels in the Perforce repository.
Additionally, these endpoints do not require POST requests, resulting in a
cross-site request forgery (CSRF) vulnerability.
SECURITY-1516 / CVE-2020-2143
Logstash Plugin stores credentials in its global configuration file
`jenkins.plugins.logstash.LogstashConfiguration.xml` on the Jenkins master
as part of its configuration.
While the credentials are stored encrypted on disk, they are transmitted in
plain text as part of the configuration form by Logstash Plugin 2.3.1 and
earlier. This can result in exposure of the credential through browser
extensions, cross-site scripting vulnerabilities, and similar situations.
SECURITY-1702 / CVE-2020-2144
Rundeck Plugin 3.6.6 and earlier does not configure its XML parser to
prevent XML external entity (XXE) attacks.
This allows a user with Overall/Read access to have Jenkins parse a crafted
HTTP request with XML data that uses external entities for extraction of
secrets from the Jenkins master or server-side request forgery.
SECURITY-1596 / CVE-2020-2145
Zephyr Enterprise Test Management Plugin 1.9.1 and earlier stores its
Zephyr password in plain text in the global configuration file
`com.thed.zephyr.jenkins.reporter.ZeeReporter.xml`. This password can be
viewed by users with access to the Jenkins master file system.
SECURITY-1692 / CVE-2020-2146
Mac Plugin 1.1.0 and earlier does not use SSH host key validation when
connecting to Mac Cloud host launched by the plugin. This lack of
validation could be abused using a man-in-the-middle attack to intercept
these connections to build agents.
SECURITY-1761 / CVE-2020-2147 (CSRF) & CVE-2020-2148 (missing permission check)
Mac Plugin 1.1.0 and earlier 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 SSH host 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.
SECURITY-1520 / CVE-2020-2149
Repository Connector Plugin stores credentials in its global configuration
file
`org.jvnet.hudson.plugins.repositoryconnector.RepositoryConfiguration.xml`
on the Jenkins master as part of its configuration.
While the credentials are stored encrypted on disk, they are transmitted in
plain text as part of the configuration form by Repository Connector Plugin
1.2.6 and earlier. This can result in exposure of the credential through
browser extensions, cross-site scripting vulnerabilities, and similar
situations.
As of publication of this advisory, there is no fix.
SECURITY-1523 / CVE-2020-2150
Sonar Quality Gates Plugin stores credentials in its global configuration
file `org.quality.gates.jenkins.plugin.GlobalConfig.xml` on the Jenkins
master as part of its configuration.
While the credentials are stored encrypted on disk, they are transmitted in
plain text as part of the configuration form by Sonar Quality Gates Plugin
1.3.1 and earlier. This can result in exposure of the credential through
