Jenkins Job Import Plugin allows enumeration of stored credential IDs due to missing permission check

Jenkins Job Import Plugin 143.v044a_2e819b_27 and earlier does not perform a permission check in an HTTP endpoint, allowing attackers with Overall/Read permission to enumerate credentials IDs of credentials stored in Jenkins.

Jenkins Job Import Plugin 3.5 and earlier does not perform a permission check in an HTTP endpoint, allowing attackers with Overall/Read permission to enumerate credentials IDs of credentials stored in Jenkins.

A data modification vulnerability exists in Jenkins Job Import Plugin 3.0 and earlier in JobImportAction.java that allows attackers to copy jobs from a preconfigured other Jenkins instance, potentially installing additional plugins necessary to load the imported job's configuration.

An exposure of sensitive information vulnerability exists in Jenkins Job Import Plugin 2.1 and earlier in src/main/java/org/jenkins/ci/plugins/jobimport/JobImportAction.java, src/main/java/org/jenkins/ci/plugins/jobimport/JobImportGlobalConfig.java, src/main/java/org/jenkins/ci/plugins/jobimport/model/JenkinsSite.java that allows attackers with Overall/Read permission to have Jenkins connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

An XML external entity processing vulnerability exists in Jenkins Job Import Plugin 2.1 and earlier in src/main/java/org/jenkins/ci/plugins/jobimport/client/RestApiClient.java that allows attackers with the ability to control the HTTP server (Jenkins) queried in preparation of job import to read arbitrary files, perform a denial of service attack, etc.
