**Descriptions****Missing hostname validation in Mailer Plugin**

**SECURITY-1813 / CVE-2020-2252**  
**Severity (CVSS):** Medium  
**Affected plugin: mailer**  
**Description:**

Mailer Plugin 1.32 and earlier does not perform hostname validation when connecting to the configured SMTP server. This lack of validation could be abused using a man-in-the-middle attack to intercept these connections.

Mailer Plugin 1.32.1 validates the SMTP hostname when connecting via TLS by default. In Mailer Plugin 1.32 and earlier, administrators can set the Java system property mail.smtp.ssl.checkserveridentity to true on startup to enable this protection.

In case of problems, this protection can be disabled again by setting the Java system property mail.smtp.ssl.checkserveridentity to false on startup.

**Missing hostname validation in Email Extension Plugin**

**SECURITY-1851 / CVE-2020-2253**  
**Severity (CVSS):** Medium  
**Affected plugin: email-ext**  
**Description:**

Email Extension Plugin 2.75 and earlier does not perform hostname validation when connecting to the configured SMTP server. This lack of validation could be abused using a man-in-the-middle attack to intercept these connections.

Email Extension Plugin 2.76 validates the SMTP hostname when connecting via TLS by default. In Email Extension Plugin 2.75 and earlier, administrators can set the Java system property mail.smtp.ssl.checkserveridentity to true on startup to enable this protection. Alternatively, this protection can be enabled (or disabled in the new version) via the 'Advanced Email Properties' field in the plugin’s configuration in Configure System.

In case of problems, this protection can be disabled again by setting mail.smtp.ssl.checkserveridentity to false using either method.

**Path traversal vulnerability in Blue Ocean Plugin**

**SECURITY-1956 / CVE-2020-2254**  
**Severity (CVSS):** Medium  
**Affected plugin: blueocean**  
**Description:**

Blue Ocean Plugin 1.23.2 and earlier provides an undocumented feature flag, blueocean.features.GIT_READ_SAVE_TYPE, that when set to the value clone allows an attacker with Item/Configure or Item/Create permission to read arbitrary files on the Jenkins controller file system.

**Descriptions****Stored XSS vulnerability in help icons**

**SECURITY-1955 / CVE-2020-2229**  
**Severity (CVSS):** High  
**Description:**

Jenkins 2.251 and earlier, LTS 2.235.3 and earlier does not escape the tooltip content of help icons. Tooltip values can be contributed by plugins, some of which use user-specified values.

This results in a stored cross-site scripting (XSS) vulnerability.

Jenkins 2.252, LTS 2.235.4 escapes the tooltip content of help icons.

**Stored XSS vulnerability in project naming strategy**

**SECURITY-1957 / CVE-2020-2230**  
**Severity (CVSS):** High  
**Description:**

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

Jenkins 2.252, LTS 2.235.4 escapes the project naming strategy description.

**Stored XSS vulnerability in 'Trigger builds remotely'**

**SECURITY-1960 / CVE-2020-2231**  
**Severity (CVSS):** High  
**Description:**

Jenkins 2.251 and earlier, LTS 2.235.3 and earlier does not escape the remote address of the host starting a build via 'Trigger builds remotely'.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by users with Job/Configure permission or knowledge of the Authentication Token.

**SMTP password transmitted and displayed in plain text by Email Extension Plugin**

**SECURITY-1975 / CVE-2020-2232**  
**Severity (CVSS):** Low  
**Affected plugin: email-ext**  
**Description:**

Email Extension Plugin stores an SMTP password in its global configuration file hudson.plugins.emailext.ExtendedEmailPublisher.xml on the Jenkins controller as part of its configuration.

While this password is stored encrypted on disk, it is transmitted and displayed in plain text as part of the configuration form by Email Extension Plugin 2.72 and 2.73. This can result in exposure of the password.

Email Extension Plugin 2.74 transmits the SMTP password in its global configuration encrypted and masks it using a password field.

**Missing permission check in Pipeline Maven Integration Plugin allows enumerating credentials IDs**

**SECURITY-1794 (1) / CVE-2020-2233**  
**Severity (CVSS):** Medium  
**Affected plugin: pipeline-maven**  
**Description:**

Pipeline Maven Integration Plugin 3.8.2 and earlier does not perform a permission check in an HTTP endpoint.

This allows attackers with Overall/Read access to Jenkins 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 Pipeline Maven Integration Plugin 3.8.3 requires the appropriate permissions.

**CSRF vulnerability and missing permission check in Pipeline Maven Integration Plugin allow capturing credentials**

**SECURITY-1794 (2) / CVE-2020-2234 (permission check), CVE-2020-2235 (CSRF)**  
**Severity (CVSS):** High  
**Affected plugin: pipeline-maven**  
**Description:**

Pipeline Maven Integration Plugin 3.8.2 and earlier does not perform a permission check in a method implementing form validation.

This allows users with Overall/Read access to Jenkins to connect to an attacker-specified JDBC URL using attacker-specified credentials IDs obtained through another method, potentially capturing credentials stored in Jenkins.

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

Pipeline Maven Integration Plugin 3.8.3 requires POST requests and Job/Configure permission for the affected form validation method.

**Stored XSS vulnerability in Yet Another Build Visualizer Plugin**

**SECURITY-1940 / CVE-2020-2236**  
**Severity (CVSS):** High
