CVE-2025-42890 is a critical security vulnerability identified in SAP SE's SQL Anywhere Monitor (Non-GUI) version 17.0, classified under CWE-798 for the use of hard-coded credentials. The vulnerability arises because the software embeds fixed credentials directly into the codebase, which attackers can leverage to gain unauthorized access without requiring any authentication or user interaction. This flaw exposes the monitoring service to remote attackers who can exploit it over the network (AV:N), with low attack complexity (AC:L), and no privileges required (PR:N). The vulnerability's scope is complete (S:C), meaning it can affect resources beyond the initially compromised component. Successful exploitation can lead to arbitrary code execution, allowing attackers to fully compromise the confidentiality, integrity, and availability of the affected systems. Although no exploits have been observed in the wild yet, the maximum CVSS score of 10 reflects the critical nature of this vulnerability. The lack of available patches at the time of publication increases the urgency for organizations to implement interim mitigations. The SQL Anywhere Monitor is used to oversee database performance and health, making it a high-value target for attackers aiming to disrupt or control enterprise database environments.

For European organizations, the impact of CVE-2025-42890 is significant due to the widespread use of SAP products in critical sectors such as finance, manufacturing, utilities, and government. Exploitation could lead to unauthorized access to sensitive business data, disruption of database monitoring and management, and potential full system compromise. This could result in data breaches, operational downtime, and loss of trust. Given the criticality of database monitoring in maintaining enterprise IT health, attackers could leverage this vulnerability to execute ransomware, data exfiltration, or sabotage attacks. The vulnerability's network accessibility and lack of required privileges make it particularly dangerous in environments with exposed or poorly segmented networks. European organizations with interconnected IT infrastructures and compliance obligations (e.g., GDPR) face heightened risks of regulatory penalties and reputational damage if exploited.

1. Immediately audit all instances of SAP SQL Anywhere Monitor (Non-GUI) version 17.0 to identify affected systems. 2. Restrict network access to the monitoring service using firewalls or network segmentation, limiting connections to trusted administrative hosts only. 3. Remove or replace hard-coded credentials where possible by reconfiguring the service to use secure, dynamically managed authentication methods. 4. Monitor network traffic and logs for unusual access patterns or unauthorized login attempts targeting the monitoring service. 5. Apply vendor patches or updates as soon as they become available; engage with SAP support for timelines and interim fixes. 6. Implement multi-factor authentication (MFA) and enhanced access controls around database monitoring tools. 7. Conduct regular vulnerability assessments and penetration testing focused on SAP environments to detect similar weaknesses. 8. Educate IT and security teams about this vulnerability to ensure rapid detection and response.
