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 QRadar SIEM 7.5.0 through 7.5.0 Update Package 14 is vulnerable to cross-site scripting. This vulnerability allows an authenticated user to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.

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

IBM QRadar SIEM 7.5.0 through 7.5.0 Update Package 14 contains a stored cross-site scripting (XSS) vulnerability in its Web UI. An authenticated attacker can inject arbitrary JavaScript code that executes in the browsers of other users viewing the compromised interface, potentially enabling credential theft or session hijacking within trusted sessions.

MitigationApply IBM QRadar SIEM Update Package 15 or later to address this vulnerability. Additionally, implement output encoding and input validation controls as defense-in-depth measures.

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 QRadar SIEM version
    Log into the QRadar console and navigate to the 'About' page, or run 'qradar_version' via the command line on the QRadar server to retrieve the exact version and update package number.
    Affected if The installed version is 7.5.0 through 7.5.0 Update Package 14.
  2. Confirm Web UI is enabled

    Affected if Multiple users or administrators access the Web UI.
  4. Check for recent XSS indicators
    Review QRadar audit logs (Log Activity) for any suspicious JavaScript tags, script injection patterns, or anomalous content in fields that could indicate stored XSS attempts.
    Affected if Suspicious injection patterns are found in logs associated with Web UI interactions.

You are affected if your QRadar SIEM version is 7.5.0 through 7.5.0 Update Package 14 and the Web UI is accessible to authenticated users.
