CVE-2021-3834
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 · uneditedIntegria IMS in its 5.0.92 version does not filter correctly some fields related to the login.php file. An attacker could exploit this vulnerability in order to perform a cross-site scripting attack (XSS).
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 confidenceIntegria IMS version 5.0.92 contains a cross-site scripting (XSS) vulnerability in login.php due to improper input filtering of certain form fields. An attacker could inject malicious JavaScript code that executes in the victim's browser when the unfiltered input is rendered.

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 installed Integria IMS versionLocate the version file or admin interface that displays the Integria IMS version number. Common locations include the admin dashboard, a version info file in the installation directory, or the footer of the web interface.Affected if The installed version is exactly 5.0.92.
-
Locate login.php fileVerify that the login.php file exists in the web root of the Integria IMS installation.Affected if login.php is present and accessible on the server.
-
Confirm login form is functionalAccess the Integria IMS login page and verify the login form fields are operational.Affected if The login form at login.php is active and accepts user input in any field.
-
Check for user-supplied input reflectionReview the login.php source code to identify form fields that accept user input and are reflected back in the response without apparent sanitization.Affected if Any form field in login.php reflects unsanitized user input back to the browser.
The environment is affected if Integria IMS version 5.0.92 is installed and the login.php file with its form fields is accessible and operational.

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 dataImplement proper input validation and output encoding on all user-supplied fields in login.php. Use context-appropriate escaping when rendering user input back to the browser.
