CVE-2025-42889 is a SQL injection vulnerability categorized under CWE-89, affecting the SAP Starter Solution (PL SAFT) product line across numerous versions of SAP_APPL, SAP_FIN, and S4CORE. The flaw arises from improper neutralization of special elements in SQL commands, allowing authenticated attackers with low privileges to craft malicious database queries. Exploiting this vulnerability can lead to unauthorized exposure of back-end database information, impacting the confidentiality and integrity of data stored within SAP systems. The vulnerability does not affect system availability and does not require user interaction beyond authentication. The CVSS 3.1 base score is 5.4 (medium severity), reflecting network attack vector, low attack complexity, and privileges required but no user interaction. No patches have been linked yet, and no exploits are known in the wild. Given SAP's critical role in enterprise resource planning and financial management, exploitation could lead to data leakage or manipulation, undermining trust and compliance. The vulnerability affects a broad range of SAP versions, indicating a long-standing issue that requires urgent attention from organizations using these SAP products.

For European organizations, the impact of CVE-2025-42889 can be significant due to the widespread adoption of SAP solutions in industries such as manufacturing, finance, logistics, and public sector. Unauthorized database query execution could expose sensitive corporate data, including financial records, customer information, and operational details, leading to potential data breaches and regulatory non-compliance under GDPR. Although availability is not impacted, the integrity compromise could allow attackers to alter data, causing operational disruptions or fraudulent activities. The medium severity score suggests moderate risk, but the broad affected SAP versions and the critical nature of SAP systems elevate the threat. Organizations relying on SAP for core business functions must consider this vulnerability a priority to avoid reputational damage and financial loss.

1. Monitor SAP Security Notes and apply official patches from SAP as soon as they become available for the affected versions. 2. Restrict user privileges rigorously, ensuring that only trusted and necessary users have access to the SAP Starter Solution components, minimizing the attack surface. 3. Implement strict input validation and parameterized queries within custom SAP extensions or integrations to prevent injection of malicious SQL commands. 4. Enable database activity monitoring and anomaly detection to identify unusual query patterns indicative of exploitation attempts. 5. Conduct regular security audits and penetration testing focused on SAP environments to detect similar injection vulnerabilities. 6. Employ network segmentation and access controls to limit exposure of SAP backend databases to only authorized systems and personnel. 7. Educate SAP administrators and developers about secure coding practices and the risks of SQL injection in SAP modules.
