CVE-2020-6259
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, versions 15.7, 16.0, allows an attacker to access information which would otherwise be restricted leading to Missing Authorization Check.
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 confidenceSAP Adaptive Server Enterprise (ASE) versions 15.7 and 16.0 contain a missing authorization check vulnerability that allows an attacker to access restricted information under certain conditions. The flaw enables unauthorized access to data that should be protected by ASE's authorization controls.

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 SAP ASE installation and versionRun 'select @@version' or 'sp_version' in isql/ASE to retrieve the exact ASE version numberAffected if The version displayed is exactly 15.7 or 16.0
-
Verify authorization configuration for protected resourcesQuery system tables such as sysprotects, sysusers, and systhresholds to review permission settings on sensitive tables or database objectsAffected if Users without explicit grant appear to have accessed protected objects or permission gaps exist in the authorization matrix
-
Review ASE audit logs for unauthorized access patternsCheck the ASE errorlog and audit tables (sysaudits, sysauditoptions) for entries indicating access to restricted data by users lacking proper authorizationAffected if Audit records show access attempts or successful queries to protected resources by users without documented authorization
-
Inspect role and permission assignmentsUse 'sp_helpuser' and 'sp_helprole' to enumerate all users and roles, then cross-reference with access to sensitive tables identified via 'sp_help <table_name>'Affected if Users or roles without explicit permissions on protected tables are found to have accessed those tables
A user is affected if they run SAP ASE version 15.7 or 16.0 and have sensitive data protected by ASE authorization controls that may be bypassed by unauthorized users.

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 the relevant SAP security patch for CVE-2020-6259 and review ASE user permissions and role-based access controls to ensure proper authorization is enforced for sensitive resources.
