CVE-2026-0507 is an OS command injection vulnerability classified under CWE-78, found in SAP Application Server for ABAP and SAP NetWeaver RFCSDK. The flaw arises due to improper neutralization of special elements in OS commands, allowing an attacker with administrative access and adjacent network access to upload specially crafted content. When this content is processed by the vulnerable SAP components, it enables execution of arbitrary operating system commands. This can result in complete system compromise, affecting confidentiality, integrity, and availability. The vulnerability affects multiple SAP kernel versions (7.53, 7.54, 7.77, 7.89, 7.93) and RFCSDK version 7.50, as well as version 9.16. The CVSS v3.1 score is 8.4, indicating high severity, with attack vector requiring adjacent network access, low attack complexity, high privileges, no user interaction, and scope change. Although no exploits are currently known in the wild, the vulnerability poses a significant risk due to the critical nature of SAP systems in enterprise environments. The vulnerability was reserved in December 2025 and published in January 2026. The lack of available patches at the time of reporting increases urgency for mitigation through compensating controls.

For European organizations, this vulnerability poses a severe risk as SAP systems are widely used across industries such as manufacturing, finance, utilities, and public sector. Successful exploitation could lead to unauthorized command execution, enabling attackers to manipulate or exfiltrate sensitive business data, disrupt critical business processes, or deploy ransomware. The requirement for administrative privileges and adjacent network access limits the attack surface but does not eliminate risk, especially in complex network environments where lateral movement is possible. Given SAP's integral role in enterprise resource planning (ERP), a compromise could have cascading effects on supply chains, financial reporting, and compliance with regulations such as GDPR. The potential for full system compromise threatens operational continuity and data protection obligations, making this vulnerability particularly impactful for European enterprises with stringent data security requirements.

1. Apply SAP-provided patches immediately once available to address the vulnerability directly. 2. Restrict administrative access to SAP Application Server and RFCSDK components to trusted personnel only, enforcing strict network segmentation to limit adjacent network access. 3. Implement robust network monitoring and intrusion detection systems to identify anomalous activities indicative of exploitation attempts. 4. Harden SAP system configurations by disabling unnecessary services and interfaces that could be leveraged for lateral movement. 5. Enforce multi-factor authentication (MFA) for all administrative accounts to reduce risk from credential compromise. 6. Conduct regular security audits and penetration testing focused on SAP environments to detect potential weaknesses. 7. Maintain up-to-date backups and incident response plans tailored for SAP system compromise scenarios. 8. Educate SAP administrators on secure handling of uploaded content and monitoring for suspicious uploads or processing behaviors.
