CVE-2025-23193 is a medium-severity Observable Response Discrepancy (CWE-204) vulnerability in Sap Sap Basis. Its CVSS base score is 5.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Account Discovery (T1087); ranked at the 26th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to IA-6 (Authentication Feedback) and SI-11 (Error Handling) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-23193 is an information disclosure vulnerability in SAP NetWeaver Server ABAP. It allows an unauthenticated attacker to exploit differences in server responses based on the existence of a specified user, potentially revealing sensitive information about valid usernames. The issue is classified under CWE-204 (Observable Response Discrepancy) and carries a CVSS v3.1 base score of 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N), indicating medium severity with low confidentiality impact and no effects on integrity or availability.
An unauthenticated attacker with network access to the SAP NetWeaver Server ABAP can exploit this vulnerability remotely with low complexity and no user interaction required. By sending crafted requests specifying particular users, the attacker can enumerate valid user accounts through observable differences in server responses, aiding further attacks like credential guessing, but without enabling data modification or service disruption.
SAP advisories provide mitigation details, including a security note at https://me.sap.com/notes/3561264 and patches released as part of SAP Security Patch Day at https://url.sap/sapsecuritypatchday. Security practitioners should apply these updates promptly to affected systems.

Mitigating Controls (NIST 800-53 r5) AI
Obscuring authentication feedback directly stops one common source of observable response discrepancies.
Error handling explicitly requires messages that avoid revealing exploitable internal information.
Information flow enforcement can block responses that would otherwise disclose internal state to unauthorized parties.
Boundary protection monitors and filters outbound responses that could leak internal state.

Secure SDLC practices directly prevent introduction of inconsistent response behavior that leaks internal state.

Security testing can detect observable response discrepancies before deployment.
Network security controls can enforce uniform responses and suppress observable discrepancies.
Secure SDLC practices include error-handling and response standardization to avoid information disclosure.
Application security requirements typically mandate consistent, non-revealing error messages.
Secure architecture principles discourage designs that leak internal state via differing responses.
Secure coding standards explicitly require uniform error handling to prevent information leakage.
