CVE-2025-43003: CWE-749: Exposed Dangerous Method or Function in SAP_SE SAP S/4HANA (Private Cloud & On-Premise)
SAP S/4 HANA allows an authenticated attacker with user privileges to configure a field not intended for their access and create a custom UI layout displaying this field. On performing this step the attacker could gain access to highly sensitive information. This could cause a high impact on confidentiality and minimal impact on integrity and availability of the application.
AI Analysis
Technical Summary
CVE-2025-43003 is a medium-severity vulnerability identified in SAP SE's SAP S/4HANA product, specifically affecting both Private Cloud and On-Premise deployments. The vulnerability arises from an exposed dangerous method or function (CWE-749) that allows an authenticated attacker with user privileges to manipulate UI configuration settings beyond their intended access rights. Specifically, the attacker can configure a field that is normally restricted and create a custom user interface layout that includes this sensitive field. By doing so, the attacker gains unauthorized access to highly sensitive information, impacting the confidentiality of the system. The vulnerability affects multiple versions of SAP S/4HANA modules, including S4CRM versions 204, 205, 206; S4CEXT versions 107, 108; and BBPCRM versions 702, 712, 713, and 714. The CVSS v3.1 base score is 6.4, reflecting a medium severity level, with the vector indicating network attack vector (AV:N), high attack complexity (AC:H), low privileges required (PR:L), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), low integrity impact (I:L), and low availability impact (A:L). There are no known exploits in the wild at the time of publication, and no patches have been linked yet. The vulnerability primarily threatens confidentiality by exposing sensitive data through UI manipulation, with minimal impact on integrity and availability. The attack requires the attacker to have authenticated user privileges, limiting exploitation to insiders or compromised accounts. The high attack complexity suggests that exploitation is not trivial and may require specific conditions or knowledge of the system configuration.
Potential Impact
For European organizations, this vulnerability poses a significant risk to the confidentiality of sensitive business information managed within SAP S/4HANA environments. Given SAP's widespread adoption across European enterprises, especially in sectors like manufacturing, finance, and logistics, unauthorized access to sensitive data could lead to data breaches, regulatory non-compliance (e.g., GDPR violations), and reputational damage. The minimal impact on integrity and availability reduces the risk of system disruption or data tampering, but the exposure of confidential information could facilitate further targeted attacks or insider threats. Organizations operating in highly regulated industries or handling personal data are particularly vulnerable to compliance penalties and loss of customer trust. The requirement for authenticated access means that insider threats or compromised user accounts are the primary vectors, emphasizing the need for robust identity and access management controls. The medium severity rating suggests that while the vulnerability is serious, it is not easily exploitable remotely without prior access, somewhat limiting its immediate threat level but not negating the need for prompt remediation.
Mitigation Recommendations
European organizations should implement the following specific mitigation strategies: 1) Conduct a thorough audit of user privileges within SAP S/4HANA to ensure that only necessary users have access to UI configuration capabilities, minimizing the attack surface. 2) Enforce strict role-based access controls (RBAC) and regularly review roles to prevent privilege escalation or unauthorized access to sensitive configuration functions. 3) Monitor and log UI layout changes and configuration activities to detect anomalous behavior indicative of exploitation attempts. 4) Apply network segmentation and limit access to SAP management interfaces to trusted internal networks and VPNs to reduce exposure. 5) Implement strong authentication mechanisms, including multi-factor authentication (MFA), to reduce the risk of compromised credentials being used to exploit this vulnerability. 6) Stay informed on SAP security advisories and apply patches or updates promptly once available, as no patches are currently linked. 7) Conduct user training and awareness programs to reduce the risk of credential compromise and insider misuse. 8) Employ data loss prevention (DLP) tools to monitor and control sensitive data exposure through UI or export functions. These targeted measures go beyond generic advice by focusing on access control, monitoring, and proactive detection specific to the nature of this vulnerability.
