CVE-2025-12453
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 · uneditedImproper neutralization of input during web page generation ('cross-site scripting') vulnerability in OpenText™ Vertica allows Reflected XSS. The vulnerability could lead to Reflected XSS attack of cross-site scripting in Vertica management console application.This issue affects Vertica: from 10.0 through 10.X, from 11.0 through 11.X, from 12.0 through 12.X, from 23.0 through 23.X, from 24.0 through 24.X, from 25.1.0 through 25.1.X, from 25.2.0 through 25.2.X, from 25.3.0 through 25.3.X.
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 confidenceReflected XSS vulnerability in OpenText Vertica management console allows attackers to inject malicious scripts through unsanitized user input that gets reflected back in web pages. The vulnerability affects multiple version ranges spanning from version 10.0 through 25.3.X, indicating a long-standing input validation gap in the application's 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.
-
Identify Vertica installation and versionLocate the Vertica installation directory and determine the installed version number using system inventory tools or Vertica-specific commandsAffected if The installed version is >= 10.0.0-0 and < 25.4.0-0
-
Confirm management console is accessibleDetermine if the Vertica management console web interface is running and network-accessible (typically on port 8443 or 5433)Affected if The management console is exposed and the Vertica version falls within the affected range
-
Identify input reflection pointsReview web application access logs or manually test suspected input fields in the management console for reflected outputAffected if User-supplied input is reflected back in web pages without proper sanitization and the version is affected
-
Check for recent security patchesReview installed patches or hotfixes applied to the Vertica environmentAffected if No vendor patches for CVE-2025-12453 have been applied and the version remains in the vulnerable range
A user is affected if the Vertica management console is running with a version between 10.0.0-0 and 25.3.X inclusive and user input can be reflected unsanitized in web responses.

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.
dbcve · scoped25.4.0-0
Apply vendor-supplied patches for all affected Vertica versions; implement output encoding and input validation as compensating controls until patching is complete.
25.4.0-0 or later
- Review Vertica upgrade documentation and release notes for version 25.4.0-0 to understand any prerequisites
- Create a full backup of the Vertica database before upgrading
- Test the upgrade in a non-production environment first
- Stop all Vertica services and client connections
- Upgrade Vertica to version 25.4.0-0 or later following the official upgrade procedure
- Verify the upgrade was successful by checking the Vertica version
- Restart Vertica services and validate the Management Console is accessible
- Confirm the XSS vulnerability is remediated
