Authorization Bypass in SAP NetWeaver AS ABAP and ABAP Platform

CVE-2025-0063

What is CVE-2025-0063?

CVE-2025-0063 is a vulnerability found in the SAP NetWeaver AS ABAP and ABAP Platform, widely utilized for developing and running enterprise applications. This vulnerability allows unauthorized users to execute Remote Function Call (RFC) function modules without proper authorization checks. As a result, even individuals with basic privileges can manipulate data stored in an Informix database. The implications of this vulnerability are severe, as it threatens the fundamental aspects of data confidentiality, integrity, and availability, potentially compromising the overall security posture of an organization.

Technical Details

The vulnerability stems from insufficient authorization checks within the SAP NetWeaver AS ABAP and ABAP Platform when executing certain RFC function modules. Attackers exploiting this flaw can leverage their basic user privileges to access and manipulate sensitive information within the database. Given the architectural design of the platform, this vulnerability poses a risk of unauthorized data access and system functionality manipulation, paving the way for more extensive breaches or data leaks.

Potential impact of CVE-2025-0063

1. Data Breach: The lack of proper authorization checks enables attackers to potentially access sensitive data, leading to significant privacy violations and financial losses for affected organizations.

2. System Integrity Compromise: Unauthorized adjustments to the database can result in corrupted or manipulated data, undermining the accuracy and reliability of business operations impacted by the compromised systems.

3. Operational Disruption: Exploiting this vulnerability could allow attackers to affect the availability of services relying on the SAP NetWeaver platform, potentially leading to downtime and hindering critical business processes.
