CVE-2022-36918Network attack vector

Authenticated filesystem enumeration via unchecked path validation

Published Jul 27, 2022 · Updated Aug 3, 2024

Missing authorization in Jenkins Buckminster Plugin 1.1.1 and earlier allows remote authenticated users to enumerate controller file paths. The doCheckEclipseHome form-validation method passes the supplied value to java.io.File and returns distinct results for nonexistent paths, nondirectories, and paths lacking a plugins subdirectory without checking permission. Overall/Read permission is required, and repeated requests disclose filesystem structure without reading file contents.
