PacsOne Server Directory Traversal Vulnerability in DICOM Web Viewer Component

Vulnerability

A directory traversal vulnerability has been identified in PacsOne Server version 6.6.2, within the web-based DICOM viewer component. This vulnerability allows remote unauthenticated attackers to read arbitrary files by exploiting the 'path' parameter in the 'nocache.php' endpoint. Evidence of this exploitation was observed by the Shadowserver Foundation on February 7, 2025.

Impact

Exploitation of this vulnerability could lead to local file inclusion, allowing attackers to read sensitive files on the server.

Reproduction

To reproduce this vulnerability, send a GET request to the 'nocache.php' endpoint with a crafted 'path' parameter that traverses directories (using '../' sequences) to access arbitrary files. For example, targeting the Windows 'win.ini' file or the Linux '/etc/passwd' file would demonstrate the vulnerability.
