CVE-2026-2103
📋 TL;DR
CVE-2026-2103 is a hard-coded cryptographic key vulnerability in Infor SyteLine ERP that allows attackers to decrypt stored credentials including passwords, database connections, and API keys. All installations using vulnerable versions are affected since the static keys are identical across deployments. Attackers need access to both the application binary and database to exploit this vulnerability.
💻 Affected Systems
- Infor SyteLine ERP
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of all encrypted credentials leading to full system takeover, data exfiltration, and lateral movement across connected systems.
Likely Case
Credential theft enabling unauthorized access to databases, API endpoints, and user accounts within the ERP environment.
If Mitigated
Limited impact if strong network segmentation, access controls, and monitoring prevent attackers from accessing both binary and database simultaneously.
🎯 Exploit Status
Exploitation requires access to both application binary (to extract keys) and database (to access encrypted data).
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Infor security advisory for specific patched version
Vendor Advisory: https://www.infor.com/company/news/press-releases/security-advisories
Restart Required: Yes
Instructions:
1. Contact Infor support for patch availability 2. Apply vendor-provided patch 3. Restart application services 4. Rotate all affected credentials
🔧 Temporary Workarounds
Credential Rotation
allRotate all encrypted credentials to new values using proper key management
Access Restriction
allImplement strict access controls to separate application binary and database access
🧯 If You Can't Patch
- Implement network segmentation to prevent simultaneous access to application binaries and database
- Deploy additional monitoring and alerting for unusual database access patterns
🔍 How to Verify
Check if Vulnerable:
Check if application uses hard-coded encryption keys by examining binary strings or consulting vendor documentationCheck Version:
Consult Infor SyteLine documentation for version check command specific to your deploymentVerify Fix Applied:
Verify patch application through version check and test that new credentials use unique encryption keys📡 Detection & Monitoring
Log Indicators:
- Multiple failed decryption attempts
- Unusual database access patterns
- Credential extraction attempts
Network Indicators:
