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
Integer overflow in SAP Network Interface Router (SAProuter) 40.4 allows remote attackers to cause a denial of service (resource consumption) via crafted requests.

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

Integer overflow vulnerability in SAP Network Interface Router (SAProuter) version 40.4 allows remote attackers to cause denial of service through resource consumption via crafted network requests.

MitigationApply vendor-supplied patches for SAProuter 40.4; if no patch available, consider network segmentation to limit exposure to untrusted networks.

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. Verify SAProuter installation
    Locate the SAP Network Interface Router (SAProuter) binary or service on the system. Check common installation directories or use system tools to find running SAProuter processes.
    Affected if SAProuter is not installed or not present on the system
  2. Determine installed SAProuter version
    Retrieve the version information of the installed SAProuter instance using the method supported by your installation (for example, checking the binary version, service information, or SAP management tools).
    Affected if Unable to determine the version or no version information is available
  3. Compare version to affected release
    Compare your installed SAProuter version against the affected version 40.4. Confirm the exact version number reported by your installation.
    Affected if The installed version is exactly 40.4
  4. Assess network exposure
    Determine whether SAProuter is listening on network interfaces accessible from untrusted networks, as the vulnerability is exploited through crafted network requests.
    Affected if SAProuter is exposed to untrusted or external networks

You are affected if your environment runs SAProuter version exactly 40.4 and the service is network-accessible.
