Unauthenticated remote peers can query and download patient demographics and medical imagery from dcm4chee-arc-light archives left in their default configuration, because the DICOM listener accepts association requests from calling AE titles that were never registered. An attacker who can reach the archive's DICOM service (commonly TCP 11112) can use C-FIND and C-GET to enumerate and retrieve patient records, and C-STORE to file fabricated studies under an existing patient identity, corrupting the clinical record. Exploitation requires no credentials and no user interaction (CVSS:3.1 AV:N/AC:L/PR:N/UI:N/C:H/I:H/A:N); no public exploit code and no confirmed in-the-wild exploitation are identified at time of analysis, so the high severity is driven by the confidentiality and integrity impact on protected health information rather than by observed attacks.
