CVE Alert: CVE-2025-42916 – SAP_SE – SAP S/4HANA (Private Cloud or On-Premise)
CVE-2025-42916
Due to missing input validation, an attacker with high privilege access to ABAP reports could delete the content of arbitrary database tables, if the tables are not protected by an authorization group. This leads to a high impact on integrity and availability of the database but no impact on confidentiality.
AI Summary Analysis
Risk verdict
High risk: an attacker with adjacent-network access and high privileges could inflict severe data integrity and availability impact, making this a priority concern in exposed environments.
Why this matters
Missing input validation in ABAP reporting can enable deletion of arbitrary database table content if not protected by an authorization group, compromising core ERP operations. The resulting data integrity loss and potential service disruption can affect finance, logistics, and regulatory reporting, with potential cascading business impact.
Most likely attack path
An attacker on the same network could leverage the unvalidated input in ABAP reports to trigger destructive operations, provided they already hold high privileges. No user interaction is required, and the scope could broaden across related tables or modules if access controls are misconfigured, increasing blast radius.
Who is most exposed
Organizations with on-premises or private-cloud ERP deployments featuring custom ABAP reports and uneven application of authorization groups to sensitive tables are most at risk, especially where network segmentation is weak or monitoring of ABAP activity is limited.
Detection ideas
- Unexpected mass deletes or modifications to key database tables via ABAP reporting.
- High-privilege ABAP report executions outside normal business workflow.
- Anomalous input patterns or validation errors in ABAP report parameters.
- Privilege or authorization group changes preceding unusual report activity.
- Audit logs showing destructive operations initiated from the ABAP layer.
Mitigation and prioritisation
- Apply SAP-provided security patches or upgrade to patched releases; verify remediation in a test environment before production.
- Enforce strict input validation and parameter handling in all ABAP reports; restrict sensitive tables to approved authorization groups.
- Tighten ABAP access controls; implement least-privilege for report execution and regular review of privileges.
- Enable comprehensive monitoring of ABAP report activity and database DMLs; alert on destructive operations.
- Change-management: test fixes in QA, obtain approval, and deploy during a maintenance window.
- If KEV evidence or EPSS ≥ 0.5, treat as priority 1.
