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
Directory traversal vulnerability in scheduler/ui/js/ffffffffbca41eb4/UIUtilJavaScriptJS in SAP NetWeaver Application Server Java 7.5 allows remote attackers to read arbitrary files via a .. (dot dot) in the query string, as exploited in the wild in August 2017, aka SAP Security Note 2486657.

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 · high confidence

Directory traversal vulnerability in SAP NetWeaver AS Java 7.5 scheduler UI component allows remote attackers to read arbitrary files via .. (dot dot) sequences in the query string of the UIUtilJavaScriptJS endpoint.

MitigationApply SAP Security Note 2486657 immediately. Until patch is available, consider network-level blocking of the affected scheduler/ui/js/ path or disabling the scheduler application if not required.

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 Java version
    Access the SAP NetWeaver Administrator or use transaction SM51 to view the installed release version. Alternatively, check the system info via the SAP Management Console or query the kernel version using the SAP kernel executables.
    Affected if The installed version is exactly 7.50 (SAP NetWeaver AS Java 7.5)
  2. Verify scheduler application is deployed
    Check if the SAP Scheduler application is installed by accessing the SAP NetWeaver Administrator and navigating to Applications or use transaction SE16 to query table WD应用程序 (or check via SDM/SLM).
    Affected if The scheduler application is deployed and running on the system
  3. Confirm vulnerable endpoint is accessible
    Attempt to access the URL pattern: /scheduler/ui/js/UIUtilJavaScriptJS on your SAP NetWeaver AS Java host. For example: http://<host>:<port>/scheduler/ui/js/UIUtilJavaScriptJS
    Affected if The endpoint returns a response (200 OK) rather than a 404 error, indicating the scheduler UI is accessible
  4. Test for directory traversal vulnerability
    Send a crafted request to the endpoint with path traversal sequences, such as: /scheduler/ui/js/UIUtilJavaScriptJS?/..//..//..//..//windows/win.ini or /scheduler/ui/js/UIUtilJavaScriptJS?/..//..//..//..//etc/passwd
    Affected if The response contains contents of the requested arbitrary file (win.ini, passwd, etc.) confirming the directory traversal is exploitable

Your environment is affected if you are running SAP NetWeaver AS Java version 7.50, the scheduler UI component is deployed, and the /scheduler/ui/js/UIUtilJavaScriptJS endpoint is accessible and responds with arbitrary file contents to traversal payloads.

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

Apply SAP Security Note 2486657 immediately. Until patch is available, consider network-level blocking of the affected scheduler/ui/js/ path or disabling the scheduler application if not required.

Recommended fix High confidence

SAP NetWeaver Application Server Java 7.50 with Security Note 2486657 applied (or upgrade to later supported version if available)

  1. 1. Obtain SAP Security Note 2486657 from the SAP Support Portal (support.sap.com)
  2. 2. Review the security note for the specific patch/instructions for SAP NetWeaver Application Server Java 7.50
  3. 3. Apply the patch according to SAP's standard security update procedures
  4. 4. After patching, verify the vulnerability is resolved by attempting the original path traversal request (scheduler/ui/js/ffffffffbca41eb4/UIUtilJavaScriptJS?..%2F..%2F) and confirming it is blocked
  5. 5. Ensure the SAP system is restarted if required by the patch
Caveat Review SAP Security Note 2486657 for any compatibility considerations or required configuration changes after applying the patch
