CVE-2020-6253
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 · uneditedUnder certain conditions, SAP Adaptive Server Enterprise (Web Services), versions 15.7, 16.0, allows an authenticated user to execute crafted database queries to elevate their privileges, modify database objects, or execute commands they are not otherwise authorized to execute, leading to SQL Injection.
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 · moderate confidenceSQL injection vulnerability in SAP Adaptive Server Enterprise web services (versions 15.7, 16.0) allows authenticated users to execute crafted database queries. Attackers can exploit this to elevate privileges beyond their assigned roles, modify database objects, and execute commands they are not authorized to run.

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.
-
Confirm SAP ASE versionUse the 'select @@version' command via isql/DBISQL or check the ASE configuration files to retrieve the exact installed version of SAP Adaptive Server EnterpriseAffected if The installed version is exactly 15.7 or exactly 16.0
-
Identify if web services are enabledQuery the ASE configuration or use 'sp_configure' to check if web services (wsql or SOAP/HTTP endpoints) are enabled on the serverAffected if Web services are enabled and accessible on the ASE instance
-
Verify web service endpoint exposureCheck the web service configuration files or use 'sp_webservices' to list all registered web service endpoints and their access controlsAffected if Public or minimally authenticated web service endpoints are exposed without strict input validation controls
-
Review web service user permissionsExamine the ASE user roles and permissions assigned to accounts that can access web services, particularly any accounts with elevated privilegesAffected if Users with weak or overly permissive roles have access to web service interfaces
-
Inspect recent web service query logsReview ASE error logs and web service access logs for unusual or malformed SQL queries that may indicate exploitation attemptsAffected if Logs show unexpected SQL patterns, privilege escalation attempts, or unauthorized query executions through web service endpoints
A user is affected if they run SAP ASE versions 15.7 or 16.0 with web services enabled and accessible to authenticated users, particularly if those users have limited input validation controls on web service interfaces.

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-2020-6253 when available. Until then, implement strict input validation on all web service interfaces, enforce least-privilege user roles, and consider disabling vulnerable web service features if not required.
