CVE-2025-42982 is a critical authorization bypass vulnerability identified in SAP GRC (Governance, Risk, and Compliance) Access Control Plugin, specifically affecting versions GRCPINW V1100_700 and V1100_731. The vulnerability stems from missing authorization checks (CWE-862), allowing non-administrative users to initiate transactions that should be restricted. This flaw permits unauthorized users to access and manipulate system credentials transmitted within the application, potentially enabling privilege escalation or lateral movement within the enterprise environment. The vulnerability has a CVSS 3.1 base score of 8.8, reflecting its high impact on confidentiality, integrity, and availability. The attack vector is network-based with low complexity, requiring only limited privileges (PR:L) and no user interaction, making it a significant threat in environments where SAP GRC is deployed. SAP GRC is widely used by large enterprises for compliance and risk management, meaning exploitation could lead to unauthorized access to sensitive business processes and critical system credentials. No public exploits have been reported yet, but the vulnerability's nature and impact necessitate urgent attention. The absence of available patches at the time of disclosure increases the risk window for affected organizations.

The vulnerability allows unauthorized users to bypass authorization controls and manipulate system credentials, which can lead to severe consequences including unauthorized access to sensitive data, modification of critical configurations, and disruption of compliance processes. Confidentiality is compromised as attackers could extract or alter credentials, integrity is affected by unauthorized transaction initiation and potential data tampering, and availability could be impacted if attackers disrupt or disable critical SAP GRC functions. Organizations relying on SAP GRC for regulatory compliance and risk management may face operational disruptions, regulatory penalties, and reputational damage. The ease of exploitation combined with the critical role of SAP GRC in enterprise environments amplifies the potential impact, making this a high-risk vulnerability for global organizations.

Organizations should immediately review user privileges within SAP GRC to ensure that only authorized administrators have access to sensitive transactions. Implement strict role-based access controls (RBAC) and regularly audit user permissions to detect and remove excessive privileges. Monitor SAP GRC logs for unusual transaction initiation by non-administrative users. Until patches become available, consider applying compensating controls such as network segmentation to limit access to SAP GRC components, and enforce multi-factor authentication (MFA) for all users with elevated privileges. Engage with SAP support to obtain any available interim fixes or guidance. Additionally, conduct penetration testing focused on authorization bypass scenarios to identify and remediate similar weaknesses. Maintain up-to-date backups and incident response plans tailored to SAP environments to quickly recover from potential exploitation.
