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 · unedited
Under certain conditions, SAP Adaptive Server Enterprise (XP Server on Windows Platform), versions 15.7, 16.0, does not perform the necessary checks for an authenticated user while executing the extended stored procedure, allowing an attacker to read, modify, delete restricted data on connected servers, leading to Code 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.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify SAP ASE installation
    Run 'select @@version' or check Windows Programs and Features for 'SAP Adaptive Server Enterprise'
    Affected if SAP Adaptive Server Enterprise is not installed
  2. Verify ASE version
    Execute 'select @@version' in isql or check the version displayed in SAP Sybase Central
    Affected if Version is exactly 15.7 or 16.0 (these are the only affected versions)
  3. Confirm Windows platform
    Check operating system with 'select @@osversion' or systeminfo command - this vulnerability only affects Windows
    Affected if Running on Windows (vulnerability is Windows-specific)
  4. Check if XP Server is enabled
    Query sysxp_cmdshell or check XP Server configuration via sp_configure 'xp_cmdshell' setting
    Affected if XP Server and extended stored procedures are enabled and accessible to the user

System is affected if SAP ASE versions 15.7 or 16.0 is installed on Windows with XP Server extended stored procedures enabled and accessible to the user context.
