Critical SAP S/4HANA flaw CVE-2025-42957 exposes enterprise systems to catastrophic compromise, allowing attackers to inject arbitrary code into the system, bypass authorization checks, and fully compromise the entire environment. Learn how this vulnerability can impact your organization's security posture.
Critical SAP S/4HANA flaw CVE-2025-42957 is under active exploitation, posing a significant risk to enterprise environments. The vulnerability allows attackers to inject arbitrary code, bypass authorization checks, and compromise the entire system. The flaw has a critical CVSS score of 9.9, indicating an extremely high severity level. An attacker with low-privileged access can exploit this vulnerability using a simple command injection attack. Successful exploitation can lead to unauthorized data access, creation of superuser accounts, and theft of password hashes. The vulnerability affects all SAP S/4HANA releases and requires immediate action from affected organizations. Security patches have been released by SAP, but organizations are advised to prioritize timely patching and implement additional security measures.
Critical SAP S/4HANA flaw CVE-2025-42957 under active exploitation has sent shockwaves throughout the cybersecurity community, highlighting the importance of timely patching and the need for organizations to remain vigilant in the face of emerging threats. The vulnerability, which was identified by security researchers at SecurityBridge Threat Research Labs, poses a significant risk to SAP S/4HANA ERP systems, allowing attackers to inject arbitrary code into the system, bypass authorization checks, and ultimately compromise the entire enterprise environment.
The flaw, tracked as CVE-2025-42957, carries a critical CVSS score of 9.9, indicating an extremely high severity level. This score reflects the potential impact that this vulnerability could have on SAP S/4HANA systems, which are used by numerous large and mid-sized organizations worldwide to manage core business processes such as finance, supply chain, manufacturing, sales, procurement, and human resources.
According to experts at SecurityBridge, an attacker with low-privileged access to the SAP system can exploit this vulnerability using a simple command injection attack. This allows them to inject arbitrary ABAP code into the system, bypassing essential authorization checks, and effectively creating a backdoor that can be used to fully compromise the system. Furthermore, successful exploitation of this flaw can lead to unauthorized data access, creation of superuser accounts, and theft of password hashes.
The vulnerability affects all SAP S/4HANA releases, including Private Cloud and On-Premise versions, making it essential for organizations using these systems to take immediate action to address the issue. SecurityBridge experts have confirmed that an exploit for this flaw is already active in the wild, with numerous attack vectors available to attackers.
Security researchers at SecurityBridge warned that while the vulnerability has not yet reached widespread exploitation, the potential impact of this flaw should not be underestimated. "A complete system compromise with minimal effort required, where successful exploitation can easily lead to fraud, data theft, espionage, or the installation of ransomware," they reported in their advisory.
SecurityBridge also provided a demo exploit based on their own research and tooling, demonstrating the potential impact of this vulnerability. Furthermore, the expert group highlighted that the attack complexity is relatively low, requiring only low-level credentials on the SAP system, making it accessible to malicious insiders or threat actors who have gained basic user access through phishing or other means.
The vendor SAP has addressed this vulnerability on August 11, 2025, releasing patches for affected versions of S/4HANA. However, due to the widespread use of these systems across various industries, organizations are advised to prioritize timely patching and to implement additional security measures to mitigate the risk associated with this flaw.
In conclusion, the critical SAP S/4HANA flaw CVE-2025-42957 highlights the ongoing importance of maintaining robust cybersecurity postures and the need for organizations to remain vigilant in detecting and addressing emerging threats. Organizations using SAP S/4HANA systems are strongly advised to take immediate action to patch this vulnerability and implement additional security measures to protect against potential attacks.
