CVE-2024-0568
📋 TL;DR
This CVE describes an improper authentication vulnerability in Schneider Electric devices that allows unauthorized tampering of device configuration via NFC communication. Attackers with physical proximity can modify settings without proper authentication. This affects Schneider Electric products using vulnerable NFC implementations.
💻 Affected Systems
- Schneider Electric devices with vulnerable NFC implementation
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete device takeover allowing configuration changes that could disrupt operations, cause safety hazards, or enable further attacks on connected systems.
Likely Case
Unauthorized configuration changes leading to operational disruption, data manipulation, or denial of service.
If Mitigated
Limited impact if NFC access is physically restricted and devices are isolated from critical networks.
🎯 Exploit Status
Exploitation requires physical access to NFC interface but no authentication. No public exploit code identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to vendor advisory for specific fixed versions
Vendor Advisory: https://download.schneider-electric.com/files?p_Doc_Ref=SEVD-2024-044-02&p_enDocType=Security+and+Safety+Notice&p_File_Name=SEVD-2024-044-02.pdf
Restart Required: Yes
