CVE-2022-24324
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code on affected IGSS Data Server systems by sending specially crafted messages that trigger a stack-based buffer overflow. Organizations using IGSS Data Server versions prior to V15.0.0.22073 are affected, particularly those in industrial control and SCADA environments.
💻 Affected Systems
- IGSS Data Server (IGSSdataServer.exe)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with full system compromise, allowing attackers to take control of the IGSS Data Server, potentially disrupting industrial operations or pivoting to other systems.
Likely Case
Remote code execution leading to data theft, system manipulation, or installation of persistent malware in industrial control environments.
If Mitigated
Denial of service or system crashes if exploit attempts are blocked by network controls, but no code execution.
🎯 Exploit Status
The vulnerability description indicates remote exploitation without authentication is possible, and buffer overflow vulnerabilities are often relatively straightforward to exploit.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: V15.0.0.22073 or later
Vendor Advisory: https://download.schneider-electric.com/files?p_enDocType=Security+and+Safety+Notice&p_File_Name=SEVD-2022-102-01_IGSS_Security_Notification_V2.0.pdf
Restart Required: Yes
Instructions:
1. Download the updated IGSS Data Server version V15.0.0.22073 or later from Schneider Electric. 2. Stop the IGSS Data Server service. 3. Install the update following vendor instructions. 4. Restart the service and verify functionality.
🔧 Temporary Workarounds
Network Segmentation
allIsolate IGSS Data Server from untrusted networks and restrict access to authorized systems only.
Firewall Rules
allBlock external access to IGSS Data Server ports and restrict internal access to necessary systems.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate the vulnerable system from all untrusted networks
- Deploy intrusion prevention systems (IPS) with signatures for buffer overflow attacks and monitor for exploit attempts
🔍 How to Verify
Check if Vulnerable:
Check the version of IGSSdataServer.exe by examining file properties or running the IGSS Data Server and checking its version information.Check Version:
Right-click IGSSdataServer.exe → Properties → Details tab, or check version information within the IGSS application interface.Verify Fix Applied:
Verify that IGSSdataServer.exe version is V15.0.0.22073 or higher after applying the update.📡 Detection & Monitoring
