CVE-2017-14853
📋 TL;DR
CVE-2017-14853 is a critical code injection vulnerability in Orpak SiteOmat OrCU components that allows attackers to execute arbitrary shell commands by tampering with search queries. This affects all versions prior to September 25, 2017, potentially compromising industrial fuel management systems. Attackers can gain full control of vulnerable devices and access sensitive operational data.
💻 Affected Systems
- Orpak SiteOmat OrCU component
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary commands, steal sensitive fuel management data, disrupt fuel station operations, pivot to other network systems, and potentially cause physical damage or safety incidents.
Likely Case
Unauthorized access to fuel management systems, data theft of operational information, potential manipulation of fuel transactions, and establishment of persistent access for further attacks.
If Mitigated
Limited impact with proper network segmentation, command validation, and monitoring in place, potentially reduced to information disclosure without full system compromise.
🎯 Exploit Status
The vulnerability requires tampering with search requests, which can be done through network access to the vulnerable component. Public advisories provide technical details that could facilitate exploitation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Versions from 2017-09-25 onward
Vendor Advisory: https://www.orpak.com
Restart Required: Yes
Instructions:

🔧 Temporary Workarounds
Network Segmentation
allIsolate OrCU components from untrusted networks and restrict access to authorized systems only
Input Validation Implementation
allImplement strict input validation for search queries to prevent shell command injection
🧯 If You Can't Patch
- Implement strict network access controls and firewall rules to limit access to OrCU components
- Deploy network monitoring and intrusion detection systems to detect exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Check system version against affected range (pre-2017-09-25). Review system logs for unusual search queries or shell command execution patterns.Check Version:
Check system administration interface or contact Orpak support for version informationVerify Fix Applied:
Verify system version is 2017-09-25 or later. Test search functionality with various inputs to ensure no command injection occurs.📡 Detection & Monitoring
Log Indicators:
- Unusual search query patterns
- Shell command execution in application logs
- Multiple failed search attempts with special characters
Network Indicators:
- Unusual network traffic to OrCU components
- Unexpected outbound connections from OrCU systems
- Anomalous search request patterns
SIEM Query:
source="orpak_orcu" AND (message="*search*" AND (message="*;*" OR message="*|*" OR message="*`*" OR message="*$(*"))
