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
Client-side printing services SAP Cloud Print Manager and SAPSprint for SAP NetWeaver Application Server for ABAP - versions 7.70, 7.70 PI, 7.70 BYD, allow an attacker to inject code that can be executed by the application. An attacker could thereby control the behavior of the application.

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 confidence

A code injection vulnerability in SAP Cloud Print Manager and SAPSprint allows attackers to inject malicious code that gets executed by the application. This affects the client-side printing services for SAP NetWeaver AS ABAP versions 7.70, 7.70 PI, and 7.70 BYD, potentially giving attackers control over application behavior.

MitigationApply SAP security patches for this vulnerability. Until patched, restrict network access to printing services and implement input validation controls on print job submissions.

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 NetWeaver AS ABAP version
    Check the SAP system version by accessing SAP transaction SM51 or using the SAP NetWeaver Administrator. Look for version 7.70, 7.70 PI, or 7.70 BYD specifically.
    Affected if The installed version matches exactly 7.70, 7.70_pi, or 7.70byd from the affected versions list.
  2. Determine if SAPSprint service is running
    On the SAP host, check for the SAPSprint process or service. On Windows, view services via services.msc; on Unix, check for sapcpe or sprint processes. In SAP, use transaction SPRO_ADMIN or check print spool configuration.
    Affected if SAPSprint service is installed and active on the system.
  3. Determine if SAP Cloud Print Manager is in use
    Check if SAP Cloud Print Manager (CPM) components are installed. Review SAP print infrastructure configuration via transaction SP01 or SP02 for print spool administration, and verify if cloud print manager connectors are configured.
    Affected if SAP Cloud Print Manager is deployed or configured in the environment.
  4. Inspect print job submission configuration
    Review print job submissions via SAP transaction SP01 (Output Controller) or SP02 (Spool Requests). Check for any custom print parameters, external commands, or script-based print outputs that could accept injected code.
    Affected if Print jobs can accept external inputs, custom scripts, or dynamic parameters without validation.

A system is affected if it runs SAP NetWeaver AS ABAP version 7.70, 7.70 PI, or 7.70 BYD AND has SAPSprint or SAP Cloud Print Manager services enabled and accessible.
