CVE-2024-44112 in Oil & Gas
Summary
by MITRE • 09/10/2024
Due to missing authorization check in SAP for Oil & Gas (Transportation and Distribution), an attacker authenticated as a non-administrative user could call a remote-enabled function which will allow them to delete non-sensitive entries in a user data table. There is no effect on confidentiality or availability.

The vulnerability identified as CVE-2024-44112 represents a critical authorization flaw within SAP's Oil & Gas Transportation and Distribution module. This issue stems from insufficient access control validation mechanisms that fail to properly verify user privileges before executing sensitive operations. The flaw specifically affects scenarios where authenticated users with non-administrative privileges can exploit a remotely accessible function to perform unauthorized data deletion operations within user data tables. The vulnerability manifests in the absence of proper authorization checks that should normally prevent standard users from accessing administrative functions or performing destructive operations on database entries.
The technical implementation of this vulnerability aligns with CWE-285, which categorizes improper authorization flaws in software systems. Attackers leveraging this vulnerability can bypass normal security controls by directly invoking a remote-enabled function that should typically be restricted to administrative users only. The function in question operates within the SAP environment's remote function call (RFC) framework, which allows for distributed processing and system integration. This particular flaw does not impact the confidentiality of data since no sensitive information is exposed during the deletion process, nor does it affect system availability as the deletion operations target non-sensitive entries rather than critical system components or data structures.
From an operational impact perspective, this vulnerability creates significant risk for organizations using SAP Oil & Gas Transportation and Distribution solutions. While the immediate effect appears limited to deletion of non-sensitive entries, the potential for escalation remains concerning. The flaw enables attackers to manipulate user data tables, potentially compromising data integrity and creating audit trail issues that could affect compliance requirements. The remote accessibility of this function call means that attackers could exploit this vulnerability from external network locations without requiring physical access to the system infrastructure. The attack vector directly maps to ATT&CK technique T1078.004, which covers valid accounts with elevated privileges, as the exploitation requires only standard user authentication credentials to achieve unauthorized data manipulation.
Organizations should implement immediate mitigations including enforcing strict authorization controls on all remote-enabled functions, implementing comprehensive access logging, and conducting regular privilege reviews. The recommended approach involves configuring proper authorization objects within the SAP system to ensure that only users with appropriate administrative privileges can access the vulnerable function. Additionally, network segmentation and firewall rules should be enforced to limit access to SAP systems from unauthorized network zones. Regular security assessments should validate that authorization checks are properly implemented across all remote function calls within the SAP ecosystem. System administrators should also monitor for unusual deletion patterns in user data tables and implement automated alerts for unauthorized data modification activities. The vulnerability underscores the importance of maintaining robust least privilege principles and proper segregation of duties within enterprise resource planning systems.
