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 · unedited
HCL Connections is vulnerable to reflected cross-site scripting (XSS) where an attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user after visiting the vulnerable URL which contains the malicious script code. This may allow the attacker to steal cookie-based authentication credentials and comprise a user's account then launch other attacks.

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 confidence

Reflected cross-site scripting (XSS) vulnerability in HCL Connections allows injection of malicious script code through specially crafted URLs. When users visit these URLs, the embedded script executes in their browser context, enabling attackers to steal cookie-based authentication credentials and potentially compromise user accounts.

MitigationApply vendor-provided patch for CVE-2023-37533; implement output encoding and input validation on all user-supplied parameters in affected HCL Connections endpoints.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check HCL Connections installed version
    Locate the version file or use the product administration console to determine the installed version of HCL Connections. Common locations include the product's About page in the admin interface or version metadata files in the installation directory.
    Affected if The installed version is exactly 8.0
  2. Identify accessible web endpoints
    Review the HCL Connections web interface URLs and parameters that accept user input, particularly in search functions, navigation parameters, or form submissions.
    Affected if The web interface is accessible and accepts URL parameters without proper output encoding
  3. Verify if reflected parameters exist
    Inspect HTTP requests and responses for URL parameters that are reflected back in the response without sanitization. Look for query string parameters in Connections URLs.
    Affected if User-supplied URL parameters are reflected in the response without encoding
  4. Check for pre-existing security controls
    Review web application firewall (WAF) configurations or any custom input validation filters that may already be protecting the affected endpoints.
    Affected if No input validation or output encoding is applied to user-supplied parameters in Connections URLs

You are affected if HCL Connections version 8.0 is installed and the web interface is accessible without protective encoding on reflected URL parameters.
