CVE-2025-3440
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 · uneditedIBM Security Guardium 11.5 is vulnerable to stored cross-site scripting. This vulnerability allows a privileged 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 · moderate confidenceIBM Security Guardium 11.5 contains a stored cross-site scripting vulnerability in its web interface. A privileged user can inject arbitrary JavaScript code into the Web UI that gets persistently stored and executed when other users access the affected functionality, potentially exposing credentials or session tokens within a trusted session.

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 IBM Security Guardium installationIdentify if IBM Security Guardium is installed in your environment. Check for Guardium processes, services, or the presence of Guardium installation directories.Affected if IBM Security Guardium is present in the environment
-
Check installed Guardium versionUse the Guardium CLI or web interface to determine the exact version number. In the CLI, run 'guardium_version' or access System Info through the web UI.Affected if The installed version is exactly 11.5 or exactly 12.0
-
Verify web interface is enabledCheck if the Guardium web UI (typically on port 8443 or 443) is accessible and operational. Confirm web services are running via 'guardctl status' or similar CLI commands.Affected if The Guardium web interface is exposed and operational
-
Review user activity logs for XSS patternsExamine Guardium audit logs and user activity logs for any suspicious JavaScript tags, script elements, or encoded XSS payloads in user input fields. Look in Admin > Audit Logs or equivalent log locations.Affected if Audit logs contain suspicious script tags or JavaScript code in user-generated fields
-
Inspect stored user data for malicious scriptsQuery Guardium user profile fields, configuration parameters, or custom fields where user input is stored. Check database tables or configuration files for persisted script content.Affected if Stored configuration or user data contains unrecognized script elements
Your environment is affected if you have IBM Security Guardium version 11.5 or 12.0 with the web interface enabled and the XSS payload has been injected by a privileged user.

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-supplied patches for CVE-2025-3440. Implement strict input validation and output encoding for all user-supplied data rendered in the web interface. Limit administrative privileges and monitor for suspicious user activity until the patch is applied.
