**Descriptions****XXE vulnerability in External Monitor Job Type Plugin**

**SECURITY-3133 / CVE-2023-37942**  
**Severity (CVSS):** High  
**Affected plugin: external-monitor-job**  
**Description:**

External Monitor Job Type Plugin 206.v9a\_94ff0b\_4a\_10 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

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

External Monitor Job Type Plugin 207.v98a\_a\_37a\_85525 disables external entity resolution for its XML parser.

**Password transmitted in plain text by Active Directory Plugin**

**SECURITY-3059 / CVE-2023-37943**  
**Severity (CVSS):** Low  
**Affected plugin: active-directory**  
**Description:**

Active Directory Plugin allows testing a new, unsaved configuration by performing a connection test (the button labeled "Test Domain").

Active Directory Plugin 2.30 and earlier ignores the "Require TLS" and "StartTls" options and always performs the connection test to Active directory unencrypted. This allows attackers able to capture network traffic between the Jenkins controller and Active Directory servers to obtain Active Directory credentials.

This only affects the connection test. Connections established during the login process are encrypted if the corresponding TLS option is enabled.

Active Directory Plugin 2.30.1 considers the "Require TLS" and "StartTls" options for connection tests.

**Missing permission check in Datadog Plugin allows capturing credentials**

**SECURITY-3130 / CVE-2023-37944**  
**Severity (CVSS):** Medium  
**Affected plugin: datadog**  
**Description:**

This allows attackers to use social engineering techniques to gain administrator access to Jenkins.

OpenShift Login Plugin 1.1.0.230.v5d7030b\_f5432 invalidates the existing session on login.

**Open redirect vulnerability in OpenShift Login Plugin**

**SECURITY-2999 / CVE-2023-37947**  
**Severity (CVSS):** Medium  
**Affected plugin: openshift-login**  
**Description:**

OpenShift Login Plugin 1.1.0.227.v27e08dfb\_1a\_20 and earlier improperly determines that a redirect URL after login is legitimately pointing to Jenkins.

This allows attackers to perform phishing attacks by having users go to a Jenkins URL that will forward them to a different site after successful authentication.

OpenShift Login Plugin 1.1.0.230.v5d7030b\_f5432 only redirects to relative (Jenkins) URLs.

**Missing SSH host key validation in Oracle Cloud Infrastructure Compute Plugin**

**SECURITY-3044 / CVE-2023-37948**  
**Severity (CVSS):** Medium  
**Affected plugin: oracle-cloud-infrastructure-compute**  
**Description:**

Oracle Cloud Infrastructure Compute Plugin 1.0.16 and earlier does not perform SSH host key validation when connecting to OCI clouds.

This lack of validation could be abused using a man-in-the-middle attack to intercept these connections to OCI clouds.

Oracle Cloud Infrastructure Compute Plugin 1.0.17 provides strategies for performing host key validation for administrators to select the one that meets their security needs.

The Jenkins security team has been unable to confirm the exploitability and resolution of this vulnerability.

**Missing permission check in Orka by MacStadium Plugin allows capturing credentials**

**SECURITY-3128 / CVE-2023-37949**

mabl Plugin 0.0.46 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 mabl Plugin 0.0.47 requires the appropriate permissions.

**Exposure of system-scoped credentials in mabl Plugin**

**SECURITY-3137 (2) / CVE-2023-37951**  
**Severity (CVSS):** Medium  
**Affected plugin: mabl-integration**  
**Description:**

mabl Plugin 0.0.46 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 Item/Configure permission to access and capture credentials they are not entitled to.

mabl Plugin 0.0.47 defines the appropriate context for credentials lookup.

**CSRF vulnerability and missing permission checks in mabl Plugin allow capturing credentials**

**SECURITY-3127 / CVE-2023-37952 (CSRF), CVE-2023-37953 (missing permission check)**  
**Severity (CVSS):** High  
**Affected plugin: mabl-integration**  
**Description:**

mabl Plugin 0.0.46 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.

mabl Plugin 0.0.47 requires POST requests and the appropriate permissions for the affected HTTP endpoints.

**CSRF vulnerability in Rebuilder Plugin**

**SECURITY-3033 / CVE-2023-37954**  
**Severity (CVSS):** Medium  
**Affected plugin: rebuild**  
**Description:**

This vulnerability allows attackers to rebuild a previous build.

**CSRF vulnerability and missing permission check in Test Results Aggregator Plugin**

**SECURITY-3122 / CVE-2023-37955 (CSRF), CVE-2023-37956 (missing permission check)**  
**Severity (CVSS):** Medium  
**Affected plugin: test-results-aggregator**  
**Description:**

Test Results Aggregator Plugin 1.2.13 and earlier does not perform a permission check in an HTTP endpoint 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 HTTP endpoint does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.

**CSRF vulnerability in Pipeline restFul API Plugin**

**SECURITY-3126 / CVE-2023-37957**  
**Severity (CVSS):** High  
**Affected plugin: pipeline-restful-api**  
**Description:**

Pipeline restFul API Plugin 0.11 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 have Jenkins connect to an attacker-specified URL, capturing a newly generated JCLI token that allows impersonating the victim.

**CSRF vulnerability and missing permission checks in Sumologic Publisher Plugin**

**SECURITY-3117 / CVE-2023-37958 (CSRF), CVE-2023-37959 (missing permission check)**
