Critical S/4HANA Code Injection Flaw Actively Exploited
⚠️ SAP released a patch for a critical S/4HANA vulnerability, CVE-2025-42957 (CVSS 9.9), after researchers observed a live exploit that allows low-privilege ABAP code injection and full system takeover. The flaw affects all S/4HANA deployments, including private cloud and on-premises, and can be weaponized easily because ABAP source is publicly viewable. Administrators should apply the update immediately and review account privileges, default credentials, encryption settings, and monitoring to limit risks such as data tampering, account creation with SAP_ALL, and password-hash exfiltration.
