CVE-2025-43011 is a high-severity vulnerability identified in the SAP Landscape Transformation (PCL Basis) module, affecting multiple versions including DMIS 2011 series, 2018_1_752, 2020, and S4CORE versions 102 through 108. The core issue is a missing authorization check (CWE-862) under certain conditions, which allows authenticated users with limited privileges to access restricted functionalities or sensitive data that should otherwise be inaccessible. This vulnerability does not impact the integrity or availability of the system but poses a significant confidentiality risk. The vulnerability has a CVSS 3.1 base score of 7.7, indicating a high severity level. The attack vector is network-based (AV:N), requires low attack complexity (AC:L), and privileges at the level of an authenticated user (PR:L), but no user interaction is needed (UI:N). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially compromised component. Exploiting this flaw could allow an attacker to escalate their access within the SAP Landscape Transformation environment, potentially exposing sensitive business data or configuration details. No known exploits are currently reported in the wild, and no official patches have been linked yet. Given SAP's widespread use in enterprise resource planning (ERP) and business process management, this vulnerability could have serious implications if exploited, especially in environments where strict data confidentiality is critical.

For European organizations, the impact of CVE-2025-43011 is significant due to the extensive adoption of SAP systems across industries such as manufacturing, finance, logistics, and public sector entities. Unauthorized access to sensitive data within SAP Landscape Transformation could lead to exposure of confidential business information, intellectual property, or personal data protected under GDPR. Although the vulnerability does not affect system integrity or availability, the confidentiality breach alone can result in regulatory penalties, loss of customer trust, and competitive disadvantage. The fact that exploitation requires only authenticated access but no user interaction means insider threats or compromised credentials could be leveraged to exploit this vulnerability. European organizations with complex SAP landscapes that integrate multiple business units and external partners are particularly at risk, as the scope of the vulnerability allows access beyond the initially compromised module. This could facilitate lateral movement within the SAP environment, amplifying the potential damage.

To mitigate CVE-2025-43011, European organizations should prioritize the following actions: 1) Immediately review and tighten authorization policies within SAP Landscape Transformation, ensuring that role-based access controls are strictly enforced and regularly audited. 2) Monitor and restrict privileged user accounts, implementing strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of credential compromise. 3) Conduct thorough SAP system audits to identify any anomalous access patterns or privilege escalations that could indicate exploitation attempts. 4) Apply any SAP-provided patches or security notes as soon as they become available; in the absence of patches, consider temporary compensating controls such as disabling or restricting access to vulnerable functionalities. 5) Enhance network segmentation to limit access to SAP systems only to trusted internal networks and users. 6) Educate SAP administrators and users about the risks of this vulnerability and the importance of safeguarding credentials. 7) Employ SAP security tools and monitoring solutions capable of detecting unauthorized access attempts or policy violations specific to SAP Landscape Transformation modules.
