A reflected Cross-Site Scripting (XSS) vulnerability has been identified in WeGIA, an open-source web management application primarily designed for Portuguese-speaking charitable organizations. This vulnerability can be exploited through the `cpf` parameter in the `cadastro_funcionario.php` endpoint. Attackers may leverage this flaw to inject malicious scripts, which are then reflected back to users' browsers, executing the scripts within the context of the victim's session.
The severity of this vulnerability is classified as medium, with a CVSS score of 6.4. This score indicates that while the attack complexity is low, user interaction is required for exploitation. The lack of validation and sanitization on user input in the vulnerable parameter significantly increases the risk of successful attacks. Organizations utilizing WeGIA are strongly advised to upgrade to version 3.2.6, which addresses this issue.
Risk to organizations includes potential unauthorized access to sensitive information and manipulation of user sessions. As the vulnerability requires active user interaction, it may not be as straightforward as other exploit types but still poses a significant risk, especially in environments where users are less aware of security best practices.
There are currently no known workarounds for this vulnerability, making the upgrade to the patched version essential. Organizations should prioritize patching immediately to mitigate potential risks associated with this XSS vulnerability.
Vulnerability Details
This vulnerability allows attackers to exploit the `cpf` parameter in the WeGIA application, specifically within the `cadastro_funcionario.php` endpoint. The absence of input validation means that malicious scripts can be injected effectively. The vulnerability is officially classified under CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')).
The CVSS score of 6.4 indicates medium severity, highlighting that while the attack vector is over a network and the complexity remains low, it still requires user interaction to trigger the exploit. The vulnerability impacts confidentiality and integrity but does not affect availability.
Technical Analysis
The root cause of this vulnerability is the failure to validate and sanitize user inputs within the application. Specifically, the `cpf` parameter in `cadastro_funcionario.php` does not have adequate input validation mechanisms, allowing for the injection of arbitrary scripts.
The attack vector is network-based, as it can be exploited remotely. The attack complexity is classified as low due to the straightforward nature of the XSS payload. No privileges are required to exploit this vulnerability, but user interaction is necessary, as the victim must visit a crafted URL to trigger the execution of the injected script.
In terms of impacts, the confidentiality and integrity of the application are at risk, with potential exposure of sensitive data and manipulation of user sessions. The availability remains unaffected, indicating that the application itself would remain operational even if exploited.
Risk & Impact Analysis
Organizations using WeGIA face real-world risks from this reflected XSS vulnerability. Attackers may leverage this flaw to steal sensitive information, execute unauthorized actions, or manipulate users. The impact could range from reputation damage to financial loss, especially if sensitive data is compromised.
The urgency for remediation is classified as high due to the potential for exploitation in live environments where users interact with the application. Organizations should prioritize patching this vulnerability to minimize the risk of successful attacks.

Affected Versions
All versions prior to vendor patch (3.2.6) of WeGIA are affected. Users should ensure they are running the latest version to mitigate this vulnerability.
Mitigation & Remediation
To remediate this vulnerability, organizations should upgrade to WeGIA version 3.2.6 or later. As there are no known workarounds, immediate action is necessary. Additionally, organizations can implement input validation and sanitization controls at the application layer to further enhance security.
For more comprehensive security, organizations are encouraged to consider penetration testing services that can help identify and mitigate similar vulnerabilities in the future.
Detection Guidance
Organizations should monitor application logs for unusual input patterns in the `cpf` parameter. Additionally, they should look for any signs of script execution in user sessions that could indicate exploitation attempts.
AppSecure Threat Intelligence Insight
