Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

WeGIA 是一款面向慈善机构的 Web 管理系统。在版本 3.8.6 之前，针对文件 web/html/socio/sistema/cadastro_cobranca.php 的未认证 POST 请求允许攻击者在 codigo 参数中注入带引号的 SQL 表达式。由于代码使用了 extract($_REQUEST)，该参数值被直接提取并拼接到 UPDATE 语句的 WHERE codigo= 子句中，且未进行任何验证或参数化绑定。通过为值添加引号，可以绕过 MariaDB 对 VARCHAR 类型列的类型转换机制

Vulnerability Title
WeGIA: Unauthenticated SQL Injection in cadastro_cobranca.php via "codigo" parameter
Source: CVE Program / CVE List V5
Vulnerability Description
WeGIA is a web manager for charitable institutions. Prior to 3.8.6, unauthenticated POST requests to web/html/socio/sistema/cadastro_cobranca.php can place a quoted SQL expression in the codigo parameter, which extract($_REQUEST) passes into the WHERE codigo= clause of an UPDATE statement without validation or parameter binding. Quoting the value bypasses MariaDB type conversion for the VARCHAR column and permits arbitrary SQL execution without a session. An attacker can read or modify database content, including user credential hashes and billing records in the cobrancas table. This issue is fixed in version 3.8.6.
