Published: 22 May 2025
Summary
CVE-2025-3483 is a high-severity Stack-based Buffer Overflow (CWE-121) vulnerability in Meddream Pacs Server. Its CVSS base score is 7.8 (High).
Operationally, ranked in the top 13.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
MedDream PACS Server contains a stack-based buffer overflow vulnerability in its DICOM file parsing component, tracked as CVE-2025-3483 and originally reported as ZDI-CAN-25825. The flaw stems from insufficient validation of the length of user-supplied data before it is copied into a fixed-length stack buffer, enabling remote code execution when a malformed DICOM file is processed.
Remote attackers can exploit the issue without authentication by delivering a crafted DICOM file to an affected installation. Successful exploitation grants arbitrary code execution in the context of the service account, with the vulnerability carrying a CVSS 3.1 score of 7.8 under CWE-121.
A Zero Day Initiative advisory (ZDI-25-243) has been published for the issue. The associated EPSS score remains flat at 0.0307 with no material increase observed since disclosure.
