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
IBM InfoSphere Information Server 11.7 is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM X-Force ID: 276102.

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 stored Cross-Site Scripting (XSS) vulnerability in IBM InfoSphere Information Server 11.7's Web UI. Attackers can embed malicious JavaScript code into the web interface that executes in the browsers of other users accessing the same interface. This can allow attackers to hijack trusted sessions and potentially disclose credentials or perform actions on behalf of authenticated users.

MitigationImplement proper input validation and output encoding for all user-supplied data rendered in the Web UI. Apply IBM's available patches for this vulnerability (IBM X-Force ID 276102) when released. Consider implementing Content Security Policy headers as a defense-in-depth measure.

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. Confirm IBM InfoSphere Information Server version
    Check the installed version of IBM InfoSphere Information Server by accessing the product's about or system information page in the Web UI, or by running the version check command specific to the installation (typically via IBM Installation Manager or the istool command line). Compare the reported version to 11.7.
    Affected if The installed version is exactly 11.7 (any 11.7.x release)
  2. Verify Web UI is enabled and accessible
    Confirm that the Web UI component for IBM InfoSphere Information Server is enabled and accessible. Attempt to log in to the Web UI through the standard web interface URL (typically on port 9443 or 8080 depending on installation).
    Affected if The Web UI is enabled and reachable - the XSS can only be exploited through this interface
  3. Identify user-controllable input fields in the Web UI
    Navigate through the Web UI and identify fields where authenticated users can submit or modify data that gets stored and subsequently displayed to other users. Common areas include metadata repository fields, data job descriptions, user profile fields, or project naming fields.
    Affected if User-controllable input fields exist in the Web UI that accept and store user-supplied text content
  4. Inspect stored data for potential XSS payloads
    Examine data stored in the IBM InfoSphere Information Server repository that is rendered in the Web UI. Use database query tools or the product's metadata management interfaces to inspect stored values in user-editable fields. Look for unusual HTML or script tags in field values.
    Affected if Stored data in user-editable fields contains unescaped HTML, script tags, or JavaScript event handlers that would execute when rendered in a browser

A user is affected if they are running IBM InfoSphere Information Server version 11.7 with the Web UI enabled, and if unvalidated user-supplied data can be stored and rendered in the interface without proper output encoding.

Mitigation

Implement proper input validation and output encoding for all user-supplied data rendered in the Web UI. Apply IBM's available patches for this vulnerability (IBM X-Force ID 276102) when released. Consider implementing Content Security Policy headers as a defense-in-depth measure.
