CVE-2025-31945
📋 TL;DR
An unauthenticated attacker can access other users' charger information through an authorization bypass vulnerability. This affects systems with vulnerable charging management software where user data isolation fails. Organizations using affected charging infrastructure products are at risk.
💻 Affected Systems
- Charging management systems from affected vendors
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could map charging infrastructure, identify usage patterns, and potentially combine with other vulnerabilities for further attacks on energy systems.
Likely Case
Unauthorized access to charger location, status, and user association data, enabling reconnaissance and privacy violations.
If Mitigated
Limited information disclosure with no direct system compromise if proper network segmentation and access controls are implemented.
🎯 Exploit Status
CWE-639 indicates authorization bypass through user-controlled key, suggesting simple HTTP requests may trigger the vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor-specific advisories
Vendor Advisory: https://www.cisa.gov/news-events/ics-advisories/icsa-25-105-04
Restart Required: Yes
Instructions:
1. Identify affected products from ICSA-25-105-04. 2. Contact vendor for specific patch. 3. Apply vendor-provided updates. 4. Restart affected systems. 5. Verify fix implementation.
🔧 Temporary Workarounds
Network segmentation
allIsolate charging management systems from untrusted networks
Access control restrictions
allImplement strict firewall rules to limit access to management interfaces
🧯 If You Can't Patch
- Implement network segmentation to isolate charging systems from internet
- Deploy web application firewall with authorization bypass detection rules
🔍 How to Verify
Check if Vulnerable:
Test if unauthenticated requests can access charger information intended for other users via API/web interfaceCheck Version:
Vendor-specific command; check system administration interfaceVerify Fix Applied:
Verify patch version installed and retest vulnerability with same unauthenticated requests📡 Detection & Monitoring
Log Indicators:
- Unauthenticated requests to charger information endpoints
- Access patterns showing cross-user data retrieval
Network Indicators:
- Unusual API calls to charger data endpoints from unauthenticated sources
SIEM Query:
source_ip NOT IN authenticated_users AND uri CONTAINS '/charger/' AND (uri CONTAINS '/info' OR uri CONTAINS '/status')
