CVE-2020-14492
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 · uneditedOpenClinic GA 5.09.02 and 5.89.05b does not properly neutralize user-controllable input, which may allow the execution of malicious code within the user’s browser.
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 confidenceOpenClinic GA versions 5.09.02 and 5.89.05b contain a cross-site scripting (XSS) vulnerability where user-supplied input is not properly sanitized or neutralized before being rendered in the browser, allowing execution of arbitrary JavaScript code in the context of authenticated users' sessions.

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 OpenClinic GA is installedIdentify if the OpenClinic GA web application is running in your environment. Check for open ports typically used by web servers (80, 443, 8080) or search for OpenClinic-related processes and directories.Affected if OpenClinic GA software is present in the environment
-
Identify the installed versionLocate the version information for your OpenClinic GA installation. Common methods include checking the software itself via its admin interface, examining version files in the installation directory, or querying the application for its version number.Affected if The installed version matches 5.09.02 or 5.89.05b exactly
-
Verify user authentication is enabledCheck if the application requires authentication for access. OpenClinic GA typically has a login page. Confirm that user sessions can be established.Affected if User authentication is active and users can log in to the application
-
Identify user input fieldsReview the OpenClinic GA web interface for forms and input fields that accept user data. Common areas include patient information forms, search fields, and administrative input panels.Affected if The application contains user-controllable input fields that accept and display data back to users
-
Confirm affected rendering contextTest whether user-supplied input in any field is reflected back in the browser without proper encoding. This can be done by entering a test string like <script>alert(1)</script> in input fields and observing if it executes or renders as raw HTML.Affected if User input is rendered in the browser without being sanitized or escaped, allowing script execution
You are affected if OpenClinic GA versions 5.09.02 or 5.89.05b are installed, authentication is enabled, and user-supplied input is reflected in the browser without proper sanitization, allowing execution of arbitrary JavaScript in authenticated user sessions.

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/escaping for all user-controllable input fields. Apply context-aware escaping based on where the input is rendered (HTML, JavaScript, CSS, or URL parameters). Consider deploying a content security policy (CSP) as an additional defense layer.
