CVE-2026-22537
📋 TL;DR
This vulnerability allows attackers to access sensitive files containing clear-text credentials and valuable information on charging systems. It affects systems where insufficient hardening allows the management user account to read unauthorized files. This impacts organizations using vulnerable charging infrastructure management systems.
💻 Affected Systems
- Thales charging systems (specific models not detailed in provided reference)
⚠️ 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).

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of charging infrastructure, credential theft enabling lateral movement, and potential disruption of charging services.
Likely Case
Unauthorized access to sensitive configuration files and credentials, leading to information disclosure and potential privilege escalation.
If Mitigated
Limited information disclosure if proper file permissions and access controls are implemented.
🎯 Exploit Status
Requires access to management user account but exploitation is straightforward once access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://cds.thalesgroup.com/en
Restart Required: No
Instructions:
Check Thales advisory for specific patching instructions. Implement proper file permissions and access controls.
🔧 Temporary Workarounds
Restrict file permissions
linuxImplement strict file permissions to prevent management user from accessing sensitive files
chmod 600 /path/to/sensitive/files
chown root:root /path/to/sensitive/files
Implement access controls
linuxUse access control lists or mandatory access controls to restrict file access
setfacl -m u:managementuser:--- /path/to/sensitive/files
🧯 If You Can't Patch
- Implement network segmentation to isolate charging management systems
- Monitor and audit file access by management user accounts
🔍 How to Verify
Check if Vulnerable:
Check if management user can read sensitive files containing credentials: sudo -u managementuser cat /path/to/credential/filesCheck Version:
Check system documentation or contact Thales support for version informationVerify Fix Applied:
Verify management user cannot access sensitive files after implementing permissions: sudo -u managementuser cat /path/to/credential/files (should return permission denied)📡 Detection & Monitoring
Log Indicators:
- Unauthorized file access attempts by management user
- Access to credential files outside normal operations
Network Indicators:
- Unusual network traffic from charging management systems
- Unexpected connections to credential storage locations
SIEM Query:
source="system_logs" AND user="managementuser" AND (file_access="*.conf" OR file_access="*password*" OR file_access="*credential*")
