CVE-2024-12703

7.8 HIGH

📋 TL;DR

This CVE describes a deserialization vulnerability in Schneider Electric software where a non-admin authenticated user can execute arbitrary code by opening a malicious project file. The vulnerability allows remote code execution, compromising workstation confidentiality and integrity. Affected users are those with authenticated access to vulnerable Schneider Electric software.

💻 Affected Systems

Products:
  • Schneider Electric software with project file functionality (specific products not detailed in provided reference)
Versions: Not specified in provided reference
Operating Systems: Windows workstations running Schneider Electric software
Default Config Vulnerable: ⚠️ Yes
Notes: Requires non-admin authenticated user access and opening of malicious project file

⚠️ 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).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full system compromise with remote code execution leading to data theft, lateral movement, and persistent backdoor installation.

🟠

Likely Case

Attacker gains control of the workstation, accesses sensitive project data, and potentially moves to other systems in the network.

🟢

If Mitigated

With proper network segmentation and least privilege, impact limited to isolated workstation with minimal sensitive data.

🌐 Internet-Facing: LOW (requires authenticated user and malicious file delivery)
🏢 Internal Only: HIGH (internal users can be tricked into opening malicious files via phishing or shared drives)

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Requires social engineering or file placement to deliver malicious project file to authenticated user

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Not specified in provided reference

Vendor Advisory: https://download.schneider-electric.com/files?p_Doc_Ref=SEVD-2025-014-06&p_enDocType=Security+and+Safety+Notice&p_File_Name=SEVD-2025-014-06.pdf

Restart Required: No

Instructions:

1. Review Schneider Electric advisory SEVD-2025-014-06
2. Apply vendor-provided patches
3. Verify patch installation
4. Test functionality after patching

🔧 Temporary Workarounds

Restrict project file sources

all

Only allow project files from trusted sources and implement file validation

User awareness training

all

Train users to only open project files from verified sources

🧯 If You Can't Patch

  • Implement application whitelisting to prevent unauthorized code execution
  • Segment network to isolate vulnerable workstations from critical systems

🔍 How to Verify

Check if Vulnerable:

Check if running affected Schneider Electric software version by consulting vendor advisory

Check Version:

Check software version through Schneider Electric management interface or vendor tools

Verify Fix Applied:

Verify patch installation through software version check and vendor verification tools

📡 Detection & Monitoring

Log Indicators:

  • Unusual process execution from project file opening
  • Deserialization errors in application logs
  • Unexpected network connections from workstation

Network Indicators:

  • Outbound connections to suspicious IPs after project file access
  • Unusual protocol usage from workstation

SIEM Query:

Process creation where parent process is Schneider Electric software AND command line contains suspicious patterns
