CVE-2026-2103 is a cryptographic vulnerability classified under CWE-321 affecting Infor SyteLine ERP version 10.0.8803.16889. The product uses hard-coded static cryptographic keys to encrypt sensitive credentials stored within the system, including user passwords, database connection strings, and API keys. These keys are identical across all installations, which means that if an attacker gains access to the application binary and the database, they can extract the encryption key and decrypt all stored credentials. This vulnerability arises from improper key management practices, specifically the use of static, embedded keys rather than unique, dynamically generated keys or secure key storage mechanisms. The CVSS 3.1 score of 7.1 reflects a high severity due to the high impact on confidentiality and integrity, the low complexity of attack (low privileges required, no user interaction), and the fact that exploitation requires local access to the system. Although no known exploits are currently in the wild, the vulnerability poses a significant risk because compromised credentials can lead to unauthorized access to the ERP system and connected resources. The lack of available patches at the time of publication means organizations must rely on compensating controls until a fix is released. This vulnerability highlights the critical importance of secure cryptographic key management in enterprise applications, especially those handling sensitive business data.

For European organizations using Infor SyteLine ERP, this vulnerability could result in the exposure of highly sensitive credentials, including user passwords and database connection strings. Such exposure can lead to unauthorized access to the ERP system, enabling attackers to manipulate business processes, steal intellectual property, or move laterally within the network to compromise additional systems. The integrity of stored data could be undermined if attackers alter credentials or configuration settings. Although availability is not directly impacted, the resulting breaches could cause operational disruptions and reputational damage. Given the ERP system’s role in managing critical business functions such as supply chain, finance, and manufacturing, the impact could be severe, especially for industries with stringent regulatory requirements like finance, healthcare, and manufacturing prevalent in Europe. Additionally, the uniformity of the encryption keys across all installations increases the risk that a single compromise could be leveraged against multiple organizations, amplifying the threat landscape.

European organizations should immediately implement strict access controls to limit who can access the application binaries and databases containing encrypted credentials. Employ file integrity monitoring and audit logging to detect unauthorized access attempts. Network segmentation should be used to isolate ERP systems from less trusted network zones. Until a vendor patch is available, consider encrypting sensitive data at rest using external mechanisms or database-level encryption with unique keys. Regularly review and rotate credentials stored within the ERP system where possible. Conduct thorough security assessments and penetration tests focusing on local privilege escalation and lateral movement scenarios. Engage with Infor for timely updates and patches, and plan for rapid deployment once fixes are released. Additionally, educate system administrators about the risks of hard-coded keys and encourage secure development practices for future deployments.
