CVE-2026-33134 in WeGIA
Summary
by MITRE • 03/20/2026
WeGIA is a web manager for charitable institutions. Versions 3.6.5 and below contain an authenticated SQL Injection vulnerability in the html/matPat/restaurar_produto.php endpoint. The vulnerability allows an authenticated attacker to inject arbitrary SQL commands via the id_produto GET parameter, leading to full database compromise. In the script /html/matPat/restaurar_produto.php, the application retrieves the id_produto parameter directly from the $_GET global array and interpolates it directly into two SQL query strings without any sanitization, type-casting (e.g., (int)), or using parameterized (prepare/execute) statements. This issue has been fixed in version 3.6.6.

The vulnerability identified as CVE-2026-33134 affects WeGIA, a web management platform designed for charitable institutions, specifically targeting versions 3.6.5 and earlier. This authenticated SQL injection flaw resides within the html/matPat/restaurar_produto.php endpoint, representing a critical security weakness that undermines the integrity and confidentiality of the affected system's database infrastructure. The vulnerability stems from the application's failure to properly validate and sanitize user input, creating an exploitable pathway for malicious actors who have already gained legitimate access to the system.
The technical implementation of this vulnerability demonstrates a classic case of improper input validation and sanitization practices within the application's codebase. The script directly accesses the id_produto parameter from the $_GET superglobal array and incorporates it verbatim into two distinct SQL query strings without any form of input filtering, type conversion, or parameterized query execution. This primitive approach to database interaction exposes the system to arbitrary SQL command injection, where an attacker can manipulate the database structure, extract sensitive information, modify or delete data, and potentially escalate privileges within the system. The vulnerability directly maps to CWE-89, which categorizes SQL injection flaws as a result of inadequate input validation and sanitization.
The operational impact of this vulnerability extends beyond simple data compromise, as it provides authenticated attackers with complete control over the underlying database system. Once an attacker successfully exploits this vulnerability, they can execute unauthorized database operations including but not limited to data extraction, modification, or deletion of critical information related to charitable institutions' operations. The authenticated nature of the vulnerability means that attackers must first obtain legitimate credentials, but this does not significantly reduce the risk as it still provides a pathway for privilege escalation and data manipulation within the system. The attack vector operates through standard http GET requests, making detection more challenging as legitimate administrative activities may mask malicious traffic patterns. This vulnerability aligns with ATT&CK technique T1071.004, which describes the use of application layer protocols for command and control operations, and T1566.001, which covers the exploitation of vulnerabilities in web applications through injection attacks.
The remediation for this vulnerability requires immediate implementation of proper input validation and sanitization measures within the affected application. The fix implemented in version 3.6.6 demonstrates the correct approach through the adoption of parameterized queries or proper type-casting of input parameters before database interaction. Organizations utilizing affected versions should prioritize upgrading to version 3.6.6 or later to prevent exploitation. Additional mitigations include implementing web application firewalls, conducting regular security assessments, and establishing proper input validation controls throughout the application codebase. Security practitioners should also consider implementing database activity monitoring to detect anomalous SQL query patterns that may indicate exploitation attempts. The vulnerability serves as a reminder of the critical importance of secure coding practices and the necessity of regular security testing to identify and remediate such flaws before they can be exploited by malicious actors.
