Summary
In the default configuration, the dcm4chee-arc-light archive accepts DICOM associations from an unregistered calling AE. A remote peer can use C-FIND and C-GET to enumerate and retrieve patient information and medical images. It can also use C-STORE to file fabricated study content under an existing patient identity. The weakness is CWE-306, and the CVSS 4.0 base score is 9.3 (CRITICAL).
