CVE-2023-26458 in Landscape Management
Summary
by MITRE • 04/11/2023
An information disclosure vulnerability exists in SAP Landscape Management - version 3.0, enterprise edition. It allows an authenticated SAP Landscape Management user to obtain privileged access to other systems making those other systems vulnerable to information disclosure and modification.The disclosed information is for Diagnostics Agent Connection via Java SCS Message Server of an SAP Solution Manager system and can only be accessed by authenticated SAP Landscape Management users, but they can escalate their privileges to the SAP Solution Manager system.

The vulnerability identified as CVE-2023-26458 represents a critical information disclosure weakness within SAP Landscape Management version 3.0 enterprise edition. This flaw specifically targets the diagnostic agent connection mechanism through the Java SCS Message Server component of SAP Solution Manager systems. The vulnerability operates at the intersection of authentication and privilege escalation, creating a pathway for authenticated users to access sensitive system information beyond their intended authorization scope. The issue stems from inadequate access controls within the landscape management framework that fails to properly restrict information flow between connected systems. This represents a fundamental breakdown in the principle of least privilege, where legitimate users can leverage their existing credentials to gain unauthorized access to diagnostic information from other systems within the SAP ecosystem.
The technical exploitation of this vulnerability relies on the authenticated user's ability to leverage their existing SAP Landscape Management credentials to traverse system boundaries and access diagnostic agent connections. The flaw manifests when users attempt to access information through the Java SCS Message Server interface, which serves as a communication channel between various SAP components. This creates an attack surface where an authenticated user can potentially escalate their privileges and access information that should remain restricted to specific system administrators or authorized personnel. The vulnerability's impact extends beyond simple information disclosure as it provides a pathway for further compromise of the SAP Solution Manager system. From a cybersecurity perspective, this aligns with CWE-284 Access Control Issues, where improper access controls allow unauthorized access to system resources. The vulnerability demonstrates how interconnected SAP systems can create cascading security risks when proper boundary controls are not implemented.
The operational impact of CVE-2023-26458 poses significant risks to enterprise SAP environments, particularly those utilizing SAP Landscape Management for system monitoring and administration. Organizations may experience unauthorized access to sensitive diagnostic information, including system configurations, user credentials, and operational data that could be leveraged for further attacks. The vulnerability's ability to escalate privileges to the SAP Solution Manager system creates a particularly dangerous scenario where attackers can move laterally within the SAP infrastructure. This could enable comprehensive reconnaissance of the enterprise's SAP landscape, potentially exposing other systems and applications within the SAP ecosystem. The risk is amplified by the fact that SAP Landscape Management users typically possess elevated privileges within the SAP environment, making this vulnerability particularly attractive to threat actors seeking to establish persistent access. This scenario aligns with ATT&CK technique T1078 Valid Accounts, where legitimate credentials are used to gain access to systems, and T1566 Phishing, as the vulnerability could be exploited through social engineering to obtain legitimate user credentials.
Organizations should implement immediate mitigations including restricting access to SAP Landscape Management functionality to only essential personnel with proper authorization, implementing additional authentication controls, and monitoring for unauthorized access attempts to diagnostic information. The recommended approach involves deploying network segmentation to isolate SAP Landscape Management components from critical systems, implementing role-based access controls with strict privilege limitations, and establishing comprehensive audit logging for all diagnostic access activities. Regular security assessments should be conducted to identify similar access control weaknesses in other SAP components, as this vulnerability demonstrates how interconnected systems can create unexpected attack vectors. Additionally, organizations should consider implementing SAP-specific security solutions that can monitor for anomalous access patterns and provide real-time alerts for potential privilege escalation attempts. The vulnerability underscores the importance of maintaining current SAP security patches and implementing comprehensive security monitoring solutions that can detect and prevent unauthorized access to diagnostic information within enterprise SAP environments.
