DescriptionCVE.org

Infor SyteLine ERP uses hard-coded static cryptographic keys to encrypt stored credentials, including user passwords, database connection strings, and API keys. The encryption keys are identical across all installations. An attacker with access to the application binary and database can decrypt all stored credentials.

Executive ViewAI

Why It Matters

Syteline ERP systems running version 10.0.8803.16889 or earlier contain a hard-coded cryptographic key vulnerability that could allow unauthorized access to sensitive financial and operational data. This affects all organizations using vulnerable Syteline versions and requires immediate mitigation since no patch is currently available.

Business Impact: High

Compensating Controls

Implement strict network segmentation restricting Syteline ERP access to authorized users only; deploy Web Application Firewall rules to detect and block exploitation attempts; enforce multi-factor authentication for all ERP access; monitor audit logs for suspicious authentication patterns; restrict database connectivity to whitelisted IPs; consider disabling remote access features until patch is available; implement database activity monitoring to detect unauthorized queries.
