CVE-2019-19297

7.5 HIGH

📋 TL;DR

This vulnerability allows unauthenticated remote attackers to perform path traversal attacks on SiNVR/SiVMS Video Server's streaming service, enabling them to access and download arbitrary files from the server. All organizations using affected versions of this video surveillance software are at risk, particularly those with internet-facing deployments.

💻 Affected Systems

Products:
  • SiNVR/SiVMS Video Server
Versions: All versions before V5.0.0
Operating Systems: Not specified - likely Windows-based given Siemens products
Default Config Vulnerable: ⚠️ Yes
Notes: Affects the streaming service on default TCP port 5410. All deployments with this service enabled are vulnerable.

📦 What is this software?

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise through theft of sensitive files (credentials, configuration data, video recordings), potentially leading to data breaches, privacy violations, and operational disruption.

🟠

Likely Case

Unauthorized access to sensitive video surveillance footage, configuration files, and system logs, compromising security and privacy.

🟢

If Mitigated

Limited impact if proper network segmentation and access controls prevent external exploitation, though internal threats may still exist.

🌐 Internet-Facing: HIGH - Unauthenticated remote exploitation allows attackers to directly access files without any authentication.
🏢 Internal Only: MEDIUM - Internal attackers could exploit this, but would need network access to the streaming service port.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Path traversal vulnerabilities are typically easy to exploit with simple HTTP requests. No public exploit code was found in initial research.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: V5.0.0 or later

Vendor Advisory: https://cert-portal.siemens.com/productcert/pdf/ssa-844761.pdf

Restart Required: Yes

Instructions:

1. Download V5.0.0 or later from Siemens support portal. 2. Backup current configuration and data. 3. Install the update following Siemens documentation. 4. Restart the video server service.

🔧 Temporary Workarounds

Network Segmentation

all

Block external access to port 5410/tcp using firewall rules

# Windows Firewall: New-NetFirewallRule -DisplayName "Block SiVMS Port" -Direction Inbound -LocalPort 5410 -Protocol TCP -Action Block
# Linux iptables: iptables -A INPUT -p tcp --dport 5410 -j DROP

Service Restriction

all

Configure the streaming service to only accept connections from trusted IP addresses

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate the video server from untrusted networks
  • Deploy a web application firewall (WAF) with path traversal protection rules

🔍 How to Verify

Check if Vulnerable:

Check if SiVMS/SiNVR version is below V5.0.0 and port 5410 is accessible. Attempt to access files using path traversal patterns like '../../' in requests to the streaming service.

Check Version:

Check version in SiVMS/SiNVR administration interface or configuration files (specific command depends on installation)

Verify Fix Applied:

Verify version is V5.0.0 or higher and test that path traversal attempts no longer succeed.

📡 Detection & Monitoring

Log Indicators:

  • Unusual file access patterns in server logs
  • Multiple failed path traversal attempts
  • Access to sensitive system files from streaming service

Network Indicators:

  • Unusual traffic to port 5410 containing '../' patterns
  • Large file downloads from streaming service

SIEM Query:

source_port:5410 AND (http_uri:"../" OR http_uri:"..\\")
