How the Exploit Works

An attacker, once authenticated, can add fields to arbitrary SAP database tables and/or structures. The added fields can cause the system to trigger short dumps on user login, rendering the system unusable and causing a high impact on system availability.

Conceptual Example Code

This is a simplified, conceptual example of how the vulnerability might be exploited. In reality, the exploit would be more complex and require a deep understanding of the SAP system architecture.

CONNECT TO SAP SYSTEM
AUTHENTICATE AS USER
SELECT * FROM DATABASE_TABLE
ALTER TABLE DATABASE_TABLE
ADD COLUMN MALICIOUS_FIELD DATA_TYPE
DISCONNECT FROM SAP SYSTEM

Mitigation Guidance

It is recommended to apply the vendor’s patch immediately. If applying the patch is not immediately feasible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. However, these measures do not fully address the vulnerability and should be considered as temporary solutions until the patch can be applied.
