CVE-2026-23729 in WeGIA
Summary
by MITRE • 01/16/2026
WeGIA is a web manager for charitable institutions. Prior to 3.6.2, an Open Redirect vulnerability was identified in the /WeGIA/controle/control.php endpoint of the WeGIA application, specifically through the nextPage parameter when combined with metodo=listarDescricao and nomeClasse=ProdutoControle. The application fails to validate or restrict the nextPage parameter, allowing attackers to redirect users to arbitrary external websites. This can be abused for phishing attacks, credential theft, malware distribution, and social engineering using the trusted WeGIA domain. This vulnerability is fixed in 3.6.2.

The vulnerability described in CVE-2026-23729 represents a critical open redirect flaw within the WeGIA web management platform for charitable institutions. This security weakness exists in versions prior to 3.6.2 and specifically targets the /WeGIA/controle/control.php endpoint, making it a significant concern for organizations relying on this software for their charitable operations. The flaw manifests when the nextPage parameter is manipulated in conjunction with metodo=listarDescricao and nomeClasse=ProdutoControle, creating a pathway for malicious redirection that bypasses normal security controls. The vulnerability stems from inadequate input validation and parameter sanitization within the application's redirect mechanism, allowing attackers to inject arbitrary URLs that will be executed during the redirect process. This represents a classic example of an open redirect vulnerability where the application fails to properly validate the destination URL before performing the redirect operation, directly violating security principles that require strict input validation and output encoding. The vulnerability is particularly dangerous because it leverages the trusted WeGIA domain to execute malicious redirects, making it more convincing to end users who might not suspect that the application is being used as a vector for attack.
The technical exploitation of this vulnerability enables attackers to craft malicious URLs that appear to originate from the legitimate WeGIA domain, thereby bypassing user suspicion and security awareness measures. When users click on these crafted links, they are transparently redirected to attacker-controlled external websites, which can be used for various malicious purposes including phishing campaigns designed to harvest user credentials, distribution of malware through seemingly legitimate download links, or social engineering attacks that manipulate user behavior through trusted domain associations. The specific combination of parameters mentioned in the vulnerability description - nextPage, metodo=listarDescricao, and nomeClasse=ProdutoControle - creates a predictable attack vector that security researchers and attackers can easily exploit. This vulnerability is categorized under CWE-601 as an Open Redirect vulnerability, which is classified as a weakness that allows web applications to redirect users to external sites without proper validation. The flaw directly corresponds to ATT&CK technique T1566.001 which covers Phishing through social engineering, making it a particularly effective vector for initial access and credential theft operations. The vulnerability's impact extends beyond simple redirection as it can be chained with other attack vectors to create more sophisticated multi-stage attacks that exploit user trust in the WeGIA platform.
The operational impact of this vulnerability is substantial for charitable institutions that rely on WeGIA for their web management needs, as it creates a significant risk of credential theft, data compromise, and reputational damage. Organizations using affected versions of WeGIA face potential exposure to phishing attacks that can target both staff members and donors, creating opportunities for attackers to gain unauthorized access to sensitive institutional data and financial information. The vulnerability's ability to leverage the trusted WeGIA domain makes it particularly effective for social engineering campaigns, as users are more likely to trust redirects that appear to come from legitimate sources. This risk is exacerbated by the fact that charitable institutions often handle sensitive donor information, financial records, and operational data that could be valuable to cybercriminals. The vulnerability also represents a potential attack surface for more sophisticated campaigns that could involve credential stuffing attacks, where stolen credentials from other breaches are tested against the compromised WeGIA system. Organizations may also face regulatory compliance issues if this vulnerability leads to data breaches, particularly if they handle personally identifiable information or financial data that requires protection under various privacy regulations and industry standards.
Mitigation strategies for this vulnerability should begin with immediate deployment of the patched version 3.6.2, which addresses the core validation issue in the nextPage parameter handling. Security teams should implement comprehensive monitoring of redirect functionality within the application to detect any unauthorized redirection attempts, and establish proper input validation controls that ensure all redirect destinations are properly sanitized and validated against a known safe list of domains. Organizations should also consider implementing web application firewalls with specific rules to block suspicious redirect patterns and conduct regular security assessments of their web applications to identify similar vulnerabilities. The fix should include proper parameter validation that checks the nextPage parameter against a whitelist of allowed domains or implements strict URL validation that ensures redirection only occurs to internal application paths or explicitly approved external domains. Additionally, security awareness training for staff members should emphasize the importance of verifying redirect destinations and recognizing potential phishing attempts that exploit trusted domain names. Organizations should also implement proper logging and alerting mechanisms that can detect suspicious redirect behavior, enabling rapid response to potential exploitation attempts. The vulnerability highlights the importance of maintaining current security patches and implementing defense-in-depth strategies that include multiple layers of protection against similar open redirect vulnerabilities. This incident underscores the necessity of following secure coding practices that prevent parameter manipulation and ensure that all user-controllable inputs are properly validated before being used in critical application functions.
