CVE-2026-0498 is a critical Remote Code Execution (RCE) vulnerability affecting SAP S/4HANA versions 102. An attacker with administrative privileges can exploit a flaw in a function module exposed via Remote Function Call (RFC) to inject arbitrary ABAP code or operating system commands. This effectively creates a backdoor, potentially leading to complete system compromise and impacting the confidentiality, integrity, and availability of the SAP S/4HANA instance.
The impact of CVE-2026-0498 is severe. Successful exploitation allows an attacker to execute arbitrary code on the SAP S/4HANA server with administrative privileges. This grants them complete control over the system, enabling them to steal sensitive data (customer information, financial records, intellectual property), modify data, disrupt operations, and potentially pivot to other systems within the network. The RFC-based injection bypasses standard authorization checks, making exploitation relatively straightforward for attackers with sufficient access. This vulnerability shares similarities with other RFC injection flaws, where improper input validation allows attackers to execute malicious code within the SAP environment.
CVE-2026-0498 was publicly disclosed on 2026-01-13. Its CRITICAL CVSS score indicates a high probability of exploitation. Public proof-of-concept (PoC) code is likely to emerge, increasing the risk of widespread attacks. The vulnerability is currently listed on CISA KEV, further highlighting its importance. Active exploitation campaigns are possible, particularly targeting organizations running vulnerable SAP S/4HANA instances.

The primary mitigation for CVE-2026-0498 is to upgrade to a patched version of SAP S/4HANA. SAP has not yet released a fixed version as of the publication date. Until a patch is available, consider implementing temporary workarounds. Restrict access to the vulnerable RFC function module, limiting which users and systems can access it. Implement strict input validation on all data passed to the function module to prevent malicious code injection. Monitor RFC connections for suspicious activity and unusual command executions. Consider using a Web Application Firewall (WAF) to filter malicious requests targeting the RFC endpoint. After upgrading, confirm the vulnerability is resolved by attempting to trigger the injection scenario with a benign payload and verifying that it is blocked.
