CVE-2023-25289
📋 TL;DR
This vulnerability allows attackers to perform directory traversal attacks on the Digital Receptie virtual reception software's embedded web server. By sending specially crafted GET requests, attackers can access sensitive files outside the intended directory. Organizations using Digital Receptie version win7sp1_rtm.101119-1850 6.1.7601.1.0.65792 are affected.

📦 What is this software?
Digital Reciptie by Virtualreception
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through retrieval of sensitive configuration files, credentials, or system files leading to further attacks.
Likely Case
Exfiltration of sensitive information including configuration files, logs, and potentially credentials stored in accessible directories.
If Mitigated
Limited information disclosure restricted to non-sensitive files if proper access controls and directory restrictions are implemented.
🎯 Exploit Status
Exploit code is publicly available on Exploit-DB (ID: 51142). The attack requires no authentication and uses simple directory traversal sequences.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available or implementing workarounds.
🔧 Temporary Workarounds
Web Server Access Restriction
windowsRestrict access to the embedded web server using firewall rules or network segmentation.
netsh advfirewall firewall add rule name="Block Digital Receptie" dir=in action=block program="C:\Path\To\DigitalReceptie.exe" enable=yes
Application Whitelisting
windowsImplement application control to prevent unauthorized modifications to the Digital Receptie software.
🧯 If You Can't Patch
- Isolate the system on a segmented network with strict firewall rules limiting inbound connections.
- Implement web application firewall (WAF) rules to block directory traversal patterns in HTTP requests.
🔍 How to Verify
Check if Vulnerable:
Test by sending a crafted GET request with directory traversal sequences (e.g., GET /../../windows/system32/drivers/etc/hosts) to the embedded web server.
Check Version:
Check the software version in the application interface or installation directory properties.
Verify Fix Applied:
Retest with the same directory traversal attempts; successful requests should return 403/404 errors instead of file contents.
📡 Detection & Monitoring
Log Indicators:
- HTTP GET requests containing '../' sequences
- Unusual file access patterns from web server logs
- Access to system files from web server process
Network Indicators:
- HTTP requests with multiple directory traversal sequences (e.g., ../../)
- Unusual file extensions being requested via HTTP
SIEM Query:
source="web_server_logs" AND (http_method="GET" AND url="*../*")
