CVE-2025-23186

CVE-2025-23186: SAP NetWeaver AS ABAP RFC Destination Exposure

Vulnerability Description:

An authenticated attacker can craft a Remote Function Call (RFC) request to restricted destinations within SAP NetWeaver Application Server ABAP. This allows the attacker to expose credentials intended for remote services.

Severity:

  • CVSS Base Score: 8.5 (High)
  • Confidentiality Impact: High
  • Integrity Impact: High
  • Availability Impact: High

Known Exploit:

Attackers can exploit this vulnerability by crafting specific RFC requests to expose credentials used for remote service authentication. These exposed credentials can then be used to compromise the target remote service. This could involve unauthorized access, data manipulation, or service disruption.

Remediation / Mitigation Strategy:

  1. Identification of Vulnerable Systems: Identify all SAP NetWeaver Application Server ABAP systems that may be susceptible to CVE-2025-23186.
  2. Patch Application: Apply the relevant security patch provided by SAP SE as soon as possible. This is the primary and recommended solution. Refer to SAP Security Note associated with CVE-2025-23186.
  3. RFC Destination Authorization Hardening: Review and harden RFC destination authorizations to restrict which users and programs can access specific destinations. Implement a principle of least privilege, only granting necessary access.
  4. Destination Security Auditing: Conduct regular audits of RFC destinations to identify potentially vulnerable configurations and unauthorized access attempts. Monitor logs for suspicious RFC calls.
  5. Credential Rotation: After applying the patch, consider rotating credentials used by RFC destinations that may have been exposed. This will mitigate the risk of compromised accounts even if credentials were leaked prior to the patch.
  6. Network Segmentation: Implement network segmentation to limit the impact of a successful exploit. Segregate sensitive systems and services from less secure areas of the network.
  7. Intrusion Detection and Prevention: Deploy or enhance intrusion detection and prevention systems (IDS/IPS) to detect and block malicious RFC traffic attempting to exploit this vulnerability. Configure alerts for suspicious RFC calls.
  8. Security Awareness Training: Educate SAP administrators and developers about the risks associated with RFC vulnerabilities and best practices for secure coding and configuration.
