CVE-2023-34294Network attack vector

Information disclosure via unchecked DCM object use

Published May 3, 2024 · Updated Aug 2, 2024

Use-after-free in Santesoft LTD Sante DICOM Viewer Pro 12.2.3.0 allows remote attackers to disclose sensitive information via a crafted DCM file. The DCM parser operates on an object without first verifying that it still exists, causing access to freed memory. Exploitation requires the target to visit a malicious page or open a malicious file; the disclosure can support a separate code-execution exploit.
