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
SAP NetWeaver Enterprise Portal (KMC) does not sufficiently encode user-controlled inputs, resulting in Cross-Site Scripting vulnerability in KMC servlet. An attacker could craft a script and trick the user into clicking it. When a victim who is registered on the portal clicks on such link, confidentiality and integrity of their web browser session could be compromised.

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

This is a reflected Cross-Site Scripting (XSS) vulnerability in SAP NetWeaver Enterprise Portal's Knowledge Management Component (KMC) servlet. The application fails to properly encode user-controlled inputs, allowing attackers to inject malicious JavaScript code via crafted URLs that execute in the context of authenticated users' browser sessions when clicked.

MitigationApply output encoding to all user inputs in the KMC servlet and implement input validation. Monitor for SAP security notes and apply patches when available. Users should avoid clicking untrusted links until the patch is applied.

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 Enterprise Portal installation
    Check the SAP system information via transaction code SM37 or examine the SAP system landscape directory (SLD) for the installed product and version. Alternatively, check the SAP system overview screen during logon for the release version.
    Affected if The installed product is SAP NetWeaver Enterprise Portal and the version is exactly 7.50
  2. Verify Knowledge Management Component (KMC) is active
    Access the SAP Enterprise Portal and navigate to System Administration > System Configuration > Knowledge Management. Verify the KMC service is deployed and running. Alternatively, attempt to access a KMC servlet URL path such as /kmc or /irj/portal under the Enterprise Portal context.
    Affected if The KMC servlet is deployed and accessible in the SAP Enterprise Portal environment
  3. Confirm user input reflection in KMC servlet URLs
    Review the KMC servlet configuration and identify any URL parameters that accept user input. Test by accessing a KMC URL with a test parameter value (for example, appending ?testparam=testvalue to a known KMC endpoint) and inspect if the parameter value is reflected in the response without encoding.
    Affected if URL parameters passed to KMC servlet are reflected in the HTML response without proper encoding or sanitization
  4. Check authentication requirements
    Verify that exploitation requires an authenticated user session by attempting to access the KMC servlet URL with and without valid SAP Enterprise Portal credentials.
    Affected if The vulnerable endpoint is accessible to authenticated users, meaning a user with valid credentials could be tricked into clicking a malicious URL

The environment is affected if SAP NetWeaver Enterprise Portal version 7.50 is running with the Knowledge Management Component servlet accessible to authenticated users, and user-supplied URL parameters are reflected in responses without output encoding.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply output encoding to all user inputs in the KMC servlet and implement input validation. Monitor for SAP security notes and apply patches when available. Users should avoid clicking untrusted links until the patch is applied.

Recommended fix Moderate confidence
  1. Check SAP Security Notes for CVE-2024-47594 to obtain the relevant patch
  2. Apply the patch via SAP Support Portal after reviewing the SAP Note details
  3. Verify the fix by testing the KMC servlet with the previously identified attack vector
  4. Ensure all portal administrators are informed of the security update
