CVE-2023-27270
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSAP NetWeaver Application Server for ABAP and ABAP Platform - versions 700, 701, 702, 731, 740, 750, 751, 752, 753, 754, 755, 756, 757, 791, has multiple vulnerabilities in a class for test purposes in which an attacker authenticated as a non-administrative user can craft a request with certain parameters, which will consume the server's resources sufficiently to make it unavailable. There is no ability to view or modify any information.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is a denial-of-service vulnerability in SAP NetWeaver Application Server for ABAP. An authenticated non-administrative user can exploit test-purpose classes by crafting requests with specific parameters that excessively consume server resources, rendering the system unavailable. No data disclosure or modification is possible—only availability impact.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the SAP NetWeaver ABAP versionUse SAP transaction code SM51 to display the installed SAP system version, or query the SAP system information via system tables or the SAP Management Console. Compare the reported version to the affected list: 700, 701, 702, 731, 740, 750, 751, 752, 753, 754, 755, 756.Affected if The installed version matches one of the listed affected versions.
-
Confirm user authentication is enabledVerify that the SAP system has user authentication configured and active. Check that the system accepts authenticated sessions for non-administrative users through standard login mechanisms.Affected if Non-administrative users can authenticate to the ABAP system.
-
Check for accessible test-purpose classesReview the SAP system for test-purpose classes that may be accessible to non-administrative users. Inspect authorization role configurations to determine which users have access to development, testing, or diagnostic class functionality.Affected if Non-administrative users have authorization to invoke test-purpose classes.
-
Monitor for anomalous resource consumptionMonitor SAP system resources such as CPU, memory, and database connections during periods of high activity. Look for unusual spikes in resource usage that correlate with requests from non-administrative users.Affected if Non-administrative user requests are causing excessive resource consumption beyond normal baseline levels.
The environment is affected if the installed SAP NetWeaver ABAP version is one of the affected versions (700-756) and non-administrative users can authenticate and access test-purpose classes that can be exploited to cause excessive resource consumption.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply SAP security patches for CVE-2023-27270 to the affected NetWeaver versions. Additionally, restrict or disable access to vulnerable test classes for non-administrative users and implement monitoring for anomalous resource consumption patterns.
