CVE-2015-4957
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 · uneditedCross-site scripting (XSS) vulnerability in the Web UI in IBM Security QRadar SIEM 7.1.x before 7.1 MR2 Patch 12 allows remote authenticated users to inject arbitrary web script or HTML via a crafted URL.
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 confidenceCross-site scripting (XSS) vulnerability in the Web UI of IBM Security QRadar SIEM allows authenticated users to inject arbitrary web script or HTML via crafted URLs. The flaw affects versions 7.1.x prior to 7.1 MR2 Patch 12. This is a classic input validation failure where user-supplied URL parameters are not properly sanitized before being rendered in the web 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 checksWork through these to decide whether this CVE applies to you.
-
Confirm QRadar SIEM is installedLocate QRadar installation by checking for /opt/qradar directory or running 'rpm -qa | grep -i qradar' on Linux systems. Check services for 'qradar' or 'tomcat' processes running on ports 443 or 8443.Affected if QRadar software is not found in the environment, the CVE does not apply.
-
Identify installed QRadar versionAccess the QRadar web UI login page and note the version displayed, or use the command line: 'cat /opt/qradar/webui/etc/VERSION' or 'rpm -q qradar' to retrieve the exact version number.Affected if The displayed version shows 7.1.x prior to 7.1 MR2 Patch 12 (for example, 7.1.0, 7.1.1, 7.1 MR2 Patch 11 or earlier).
-
Verify Web UI component is enabledConfirm the QRadar web interface is accessible by attempting to reach the login page at the configured QRadar URL (typically https://<qradar_host>/). Check that the 'qradar' or 'tomcat' service is running.Affected if Web UI is enabled and accessible; if the Web UI is completely disabled or inaccessible, the XSS attack surface may not be present.
-
Confirm the specific patch levelIn the web UI, navigate to the About or Help section to view the full version string including MR (Maintenance Release) and Patch numbers. The format typically appears as '7.1 MR2 Patch 12' or similar.Affected if Version is 7.1 MR2 Patch 11 or earlier, or any 7.1.x version without the MR2 Patch 12 designation.
If QRadar SIEM version 7.1.x is installed and the Web UI is accessible with a version earlier than 7.1 MR2 Patch 12, the environment is affected by this XSS vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor patch 7.1 MR2 Patch 12 or later to resolve the XSS vulnerability. As a compensating control, consider restricting Web UI access to only trusted users and implementing Content Security Policy headers.
