CVE-2025-24850
📋 TL;DR
This vulnerability allows an attacker to export other users' plant information from affected systems, potentially exposing sensitive operational data. It affects users of specific industrial control systems where proper authorization checks are missing for export functionality.
💻 Affected Systems
- Specific industrial control systems mentioned in CISA advisory ICSA-25-105-04
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete exposure of all plant information across the system, including sensitive operational data, configuration details, and potentially proprietary information that could be used for further attacks.
Likely Case
Unauthorized access to plant information belonging to other users, leading to data leakage and potential privacy violations.
If Mitigated
Limited impact with proper access controls and monitoring in place, though some information exposure may still occur.
🎯 Exploit Status
Exploitation likely requires some level of access to the system, but the vulnerability itself is straightforward (CWE-639: Authorization Bypass Through User-Controlled Key).
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific version
Vendor Advisory: Refer to CISA advisory ICSA-25-105-04 for vendor links
Restart Required: Yes
Instructions:
1. Identify affected systems and versions
2. Obtain vendor patch from official sources

4. Restart affected systems
5. Verify patch application
🔧 Temporary Workarounds
Disable export functionality
allTemporarily disable plant information export features until patching can be completed
Check vendor documentation for disable commands
Implement network segmentation
allRestrict access to affected systems to authorized users only
🧯 If You Can't Patch
- Implement strict access controls and monitor export functionality usage
- Deploy network monitoring to detect unauthorized export attempts
🔍 How to Verify
Check if Vulnerable:
Check system version against vendor advisory and test export functionality with different user accountsCheck Version:
Check vendor documentation for version check command specific to the affected productVerify Fix Applied:
Verify patch version is installed and test that users can only export their own plant information📡 Detection & Monitoring
Log Indicators:
- Multiple export requests from single user
- Export requests for plant IDs not owned by requesting user
- Unusual export patterns or volumes
Network Indicators:
- Unusual data export traffic patterns
- Export requests to unexpected destinations
