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 3.7.3, a Stored Cross-Site Scripting (XSS) vulnerability allows an authenticated user to inject malicious JavaScript into the Processo de Aceitação (html/atendido/processo_aceitacao.php) page, which is executed when user access the the page, enabling session hijacking and account takeover. This vulnerability is fixed in 3.7.3.

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 confidence

WeGIA versions prior to 3.7.3 contain a stored XSS vulnerability in the Processo de Aceitação page (html/atendido/processo_aceitacao.php). An authenticated attacker can inject malicious JavaScript that executes when other users view the page, enabling session hijacking and account takeover.

MitigationUpgrade to WeGIA version 3.7.3 or later. If immediate upgrade is not possible, implement input validation and output encoding on the processo_aceitacao.php page to neutralize malicious script payloads.

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. Confirm WeGIA is installed
    Look for the WeGIA application directory on the server, typically in web root paths like /var/www/html/, /www/html/, or C:\inetpub\wwwroot\. Search for files named processo_aceitacao.php within the html/atendido/ subdirectory.
    Affected if The WeGIA application directory and the file html/atendido/processo_aceitacao.php are present on the server.
  2. Identify the installed WeGIA version
    Check for a version file in the WeGIA root directory, or access the application and look for a version identifier in the footer, about page, or administrative settings panel. Common version file locations include version.php, config.php, or a version constant in the main index file.
    Affected if The installed version is lower than 3.7.3 (e.g., 3.7.2, 3.7.1, 3.6.x, etc.).
  3. Verify the Processo de Aceitação page is accessible
    Attempt to access the URL path /html/atendido/processo_aceitacao.php through the web server. If the application is behind authentication, verify that the page loads (even if login is required to reach it).
    Affected if The page exists and responds, indicating the vulnerable component is exposed.
  4. Check for existing XSS payloads in the database
    Inspect the database tables that store processo_aceitacao data (such as aceitacao, processo, or atendimento tables) for suspicious script tags, javascript: URIs, or event handler attributes in input fields. Use SQL queries like: SELECT * FROM aceitacao WHERE campo LIKE '%<script%' OR campo LIKE '%onerror%'.
    Affected if Malicious scripts or event handlers are found stored in the database, confirming active exploitation.

The environment is affected if WeGIA is installed with a version prior to 3.7.3 and the processo_aceitacao.php file exists and is accessible, regardless of whether the vulnerability has been exploited yet.

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

Upgrade to WeGIA version 3.7.3 or later. If immediate upgrade is not possible, implement input validation and output encoding on the processo_aceitacao.php page to neutralize malicious script payloads.

Recommended fix Moderate confidence

3.7.3

  1. Obtain the WeGIA version 3.7.3 release from the official GitHub repository
  2. Backup the current WeGIA installation and database before proceeding
  3. Replace the existing WeGIA files with the version 3.7.3 files
  4. Verify that the processo_aceitacao.php file has been updated as part of the new version
  5. Test the Processo de Aceitação page to confirm the XSS vulnerability is no longer present
  6. Ensure all other components of WeGIA function correctly after the upgrade
