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
The Web administration UI of SAP Web Dispatcher and the Internet Communication Manager (ICM) does not sufficiently encode user-controlled inputs, resulting in Cross-Site Scripting (XSS) vulnerability.

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 reflected Cross-Site Scripting (XSS) vulnerability exists in the Web administration UI of SAP Web Dispatcher and Internet Communication Manager (ICM). The UI fails to properly encode user-controlled inputs, allowing attackers to inject malicious JavaScript code that executes in the context of an authenticated administrator's browser session.

MitigationApply the relevant SAP Security Notes to patch the vulnerability. Implement input validation and output encoding on all user-supplied data within the administration interface.

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 if SAP Web Dispatcher or ICM is installed
    Check for the presence of SAP Web Dispatcher by looking for the 'disp+work' executable or ICM-related processes. On Windows, check Program Files for SAP folder. On Unix, check /sapmnt/<SID>/exe or /usr/sap/<SID>/<instance> directories.
    Affected if The system has SAP Web Dispatcher or ICM components installed.
  2. Check installed SAP Web Dispatcher version
    Run the Web Dispatcher executable with version flag: ./disp+work -v or check the SAP Start Service (sapstartsrv) for version information via SAP Management Console or SAP MMC.
    Affected if The version matches exactly 7.22ext, 7.49, 7.53, 7.77, 7.81, 7.83, or 7.85.
  3. Check installed SAP Netweaver ABAP Kernel version
    Execute kernel version check: disp+work -version or use transaction SM51 in SAP GUI to view the kernel version, or check the kernel patch level in /usr/sap/<SID>/sys/exe/uc/<OS>/*.
    Affected if The kernel version is exactly 7.22, 7.22ext, 7.49, 7.53, 7.77, 7.81, 7.85, 7.86, 7.87, or 8.04.
  4. Verify Web administration UI is accessible
    Access the SAP Web Dispatcher administration interface by navigating to https://<host>:<port>/sap/admin/public/index.html or checking if ports 50000-50010 (default Web Dispatcher admin ports) are open and responding.
    Affected if The Web administration UI is exposed and accessible over the network.
  5. Review Web Dispatcher logs for XSS indicators
    Examine Web Dispatcher logs in the work directory for unusual URL parameters or script tags in HTTP requests. Look for entries containing patterns like <script>, javascript:, or encoded XSS payloads in the access logs.
    Affected if Logs contain suspicious requests with XSS payload patterns targeting the admin interface.

A system is affected if it runs SAP Web Dispatcher or Netweaver ABAP Kernel versions matching exactly 7.22 through 8.04 and has the Web administration UI exposed and accessible.
