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
WeGIA is a web manager for charitable institutions. In versions prior to 3.7.0, atendido/familiar_docfamiliar.php displays an overly descriptive error message, including database-related details. This verbosity leads to information disclosure, which could assist a potential attacker in mapping the backend infrastructure and expanding the attack surface. This vulnerability is fixed in 3.7.0.

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

WeGIA versions prior to 3.7.0 contain an information disclosure vulnerability in the file atendido/familiar_docfamiliar.php. The script returns overly descriptive error messages that expose database-related details such as table names, query structure, or connection information. This information can help attackers map the backend infrastructure and identify further attack vectors.

MitigationUpgrade WeGIA to version 3.7.0 or later to obtain the fix for this vulnerability. As a temporary measure, ensure custom error handlers are configured to suppress detailed database errors in production environments.

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. Locate WeGIA installation directory
    Search for the file 'atendido/familiar_docfamiliar.php' or 'atendimento/familiar_docfamiliar.php' in your web server document root or common application directories. Common paths may include /var/www/, /opt/, or C:\inetpub\wwwroot\ on Windows servers.
    Affected if The file exists in your environment, indicating WeGIA is installed and the vulnerable script is present.
  2. Determine installed WeGIA version
    Look for a version file, CHANGELOG, or configuration file in the WeGIA root directory. Common version indicators include a 'version' file, 'VERSION' constant in PHP files, or entries in a config file. Check files like 'index.php', 'config.php', or a 'VERSION' file in the application root.
    Affected if The installed version is lower than 3.7.0, or if no version can be determined and the vulnerable file is present.
  3. Verify the vulnerable script exists
    Confirm the file 'atendido/familiar_docfamiliar.php' (or 'atendimento/familiar_docfamiliar.php') exists in your WeGIA installation. Access the file via a web browser or check the filesystem directly.
    Affected if The file exists in your installation and the version is prior to 3.7.0.
  4. Check PHP error display configuration
    Review your PHP configuration (php.ini) or check for runtime error reporting settings in the application. Look for 'display_errors = On' or 'error_reporting' set to high verbosity (such as E_ALL). You can also create a simple PHP info page to check this.
    Affected if PHP display_errors is enabled (set to On or 1), which would allow the overly descriptive error messages to be rendered in the browser.

You are affected if WeGIA version is lower than 3.7.0 AND the file atendimento/familiar_docfamiliar.php exists AND PHP error display is enabled, allowing database details to be exposed in error messages.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade WeGIA to version 3.7.0 or later to obtain the fix for this vulnerability. As a temporary measure, ensure custom error handlers are configured to suppress detailed database errors in production environments.

Recommended fix Moderate confidence

3.7.0

  1. Backup the current WeGIA installation and database before upgrading
  2. Obtain WeGIA version 3.7.0 from the official source (github.com or vendor repository)
  3. Replace the existing WeGIA files with the version 3.7.0 files, ensuring theberto/familiar_docfamiliar.php is updated to the fixed version
  4. Verify the fix by testing atendidos/familiar_docfamiliar.php to confirm error messages no longer expose database details
  5. Confirm the application functions normally after the upgrade
