CVE-2019-0293 in Solution Manager
Summary
by MITRE
Read of RFC destination does not always perform necessary authorization checks, resulting in escalation of privileges to access information on RFC destinations on managed systems and SAP Solution Manager system (ST-PI, before versions 2008_1_700, 2008_1_710, and 740).

The vulnerability identified as CVE-2019-0293 represents a critical authorization flaw within SAP Solution Manager systems that affects the Secure Transaction Processing Infrastructure component. This issue stems from insufficient authorization checks during RFC destination operations, creating a pathway for unauthorized access to sensitive system information. The vulnerability specifically impacts ST-PI components running on managed systems and SAP Solution Manager environments, where proper access controls fail to validate user permissions when reading RFC destination configurations.
The technical flaw manifests in the improper handling of authorization contexts during RFC destination read operations. When users attempt to access RFC destination information, the system does not consistently enforce the necessary authorization checks that should prevent unauthorized access to destination configurations. This authorization bypass allows malicious actors or compromised users with lower privileges to escalate their access and retrieve sensitive information about RFC destinations, which may contain credentials, connection parameters, and system integration details that could be leveraged for further attacks.
The operational impact of this vulnerability extends beyond simple information disclosure, as RFC destinations often contain critical system integration data that could facilitate lateral movement within the network. Attackers could exploit this vulnerability to gather intelligence about system connections, potentially identifying other systems that share similar RFC configurations or credentials. The vulnerability affects multiple versions of SAP Solution Manager including 2008_1_700, 2008_1_710, and 740, indicating a widespread exposure across different product releases and potentially affecting organizations with legacy system configurations.
Organizations affected by this vulnerability face significant security risks including potential data exfiltration, system compromise, and unauthorized access to integration points that may connect to critical business systems. The issue aligns with CWE-284, which describes improper access control in software systems, and represents a classic privilege escalation scenario that could enable attackers to move beyond their initial access level. From an attack framework perspective, this vulnerability maps to techniques in the credential access and privilege escalation phases of the MITRE ATT&CK framework, where adversaries seek to obtain and leverage system credentials and access rights.
The recommended mitigation strategy involves applying the vendor-provided patches and updates for SAP Solution Manager ST-PI components to address the authorization bypass issue. Organizations should also implement additional monitoring and access controls around RFC destination configurations to detect and prevent unauthorized access attempts. Security teams should conduct comprehensive assessments of their SAP environments to identify all affected systems and ensure proper authorization enforcement is in place for all RFC destination operations. Regular security assessments and privilege reviews should be implemented to maintain defense in depth against similar authorization-related vulnerabilities.
