Lifecycle Timeline
4DescriptionGitHub Advisory
WeGIA is a Web manager for charitable institutions. Prior to 3.6.9, 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=listarId and nomeClasse=IsaidaControle. 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 3.6.9.
AnalysisAI
Open redirect in WeGIA web management application versions prior to 3.6.9 allows unauthenticated remote attackers to redirect users to arbitrary external websites via an unvalidated nextPage parameter in the /WeGIA/controle/control.php endpoint. By crafting a malicious URL combining metodo=listarId and nomeClasse=IsaidaControle parameters, attackers can leverage the application's trusted domain for phishing, credential harvesting, malware distribution, and social engineering attacks. The vulnerability is fixed in version 3.6.9.
Technical ContextAI
The vulnerability stems from improper input validation on the nextPage parameter in a PHP-based endpoint (CWE-601: URL Redirection to Untrusted Site). WeGIA, a web management platform for charitable institutions built in PHP, fails to sanitize or whitelist redirect destinations before performing HTTP redirects. The specific attack vector exploits the /WeGIA/controle/control.php controller endpoint when accessed with metodo=listarId and nomeClasse=IsaidaControle query parameters, which likely control request routing and processing logic. The absence of server-side validation against the nextPage parameter allows any external URL to be injected, enabling attackers to abuse the legitimate WeGIA domain (which users trust) as a redirect vector. This is a classic open redirect flaw commonly found in web applications that dynamically construct redirect URLs without proper validation.
RemediationAI
The primary remediation is to upgrade WeGIA to version 3.6.9 or later, which includes validation of the nextPage parameter and prevents arbitrary URL redirection. Organizations should immediately apply this patch to all deployed instances of WeGIA. As a temporary workaround prior to patching, implement web application firewall (WAF) rules or reverse proxy filters to block requests to /WeGIA/controle/control.php containing suspicious nextPage parameter values (e.g., those containing external domain names or URL-encoded malicious patterns). Additionally, audit access logs for exploitation attempts targeting this endpoint with the metodo=listarId and nomeClasse=IsaidaControle parameters. For deployment best practices, implement HTTP security headers such as Content-Security-Policy to mitigate redirect-based phishing attacks at the browser level. Detailed guidance and the patched version are available in the GitHub Security Advisory at https://github.com/LabRedesCefetRJ/WeGIA/security/advisories/GHSA-4qxc-5j5f-4gp5.
