A Reflected Cross-Site Scripting (XSS) vulnerability has been identified in the WeGIA web application, which is used for managing charitable institutions. This vulnerability is classified as medium severity with a CVSS score of 6.4. It allows attackers to inject malicious scripts into the application via the `avulso` parameter in the `configuracao_doacao.php` endpoint. Organizations utilizing this application are at risk, as the integrity of their data can be compromised.
The vulnerability was publicly disclosed on January 10, 2025, and it has been fixed in version 3.2.8 of the WeGIA application. It is crucial for organizations to address this vulnerability promptly to prevent potential exploitation. Risk to organizations includes unauthorized access and manipulation of user data, highlighting the urgency of immediate remediation.
The exploitation of this vulnerability is currently not known to be actively targeted in the wild. However, the nature of XSS vulnerabilities means that they can be exploited in various ways, emphasizing the need for vigilance. Organizations should prioritize patching immediately to safeguard their systems.
Given the nature of the vulnerability and its potential impact, it is essential for security teams to implement appropriate security measures and ensure their systems are updated to the latest version.
Vulnerability Details
The official description of the vulnerability states that "This vulnerability allows attackers to inject malicious scripts in the avulso parameter." The vulnerability type is classified under CWE-79, indicating a reflected cross-site scripting issue.
The CVSS score is 6.4, which indicates medium severity. The attack vector is network-based, with low complexity and no privileges required. User interaction is needed for exploitation, making it an active threat that can affect confidentiality and integrity.
Organizations using WeGIA should be aware that the vulnerability has been fixed in version 3.2.8, providing a clear path for remediation.
Technical Analysis
The root cause of this vulnerability is the lack of proper input validation in the `configuracao_doacao.php` endpoint. Attackers can exploit this flaw by injecting malicious scripts into the `avulso` parameter, which the application fails to sanitize before rendering. This vulnerability can lead to unauthorized actions being performed on behalf of the user.
The attack vector is network-based, which means that an attacker can exploit the vulnerability remotely without physical access to the target system. The attack complexity is low, as the attacker does not need special conditions to exploit the flaw. User interaction is required, as the victim must click on a malicious link or visit a compromised site.
The confidentiality impact is low, as the attacker may not gain access to sensitive data directly. However, integrity impact is high, as malicious scripts can alter user sessions or perform unauthorized actions. Availability impact is none, but the overall risk to user trust and application integrity is significant.
Risk & Impact Analysis
The risk to organizations includes potential data integrity issues that could arise from exploiting this vulnerability. Attackers may leverage this XSS vulnerability to manipulate user sessions, leading to unauthorized actions or data breaches. The blast radius can be extensive, particularly for organizations managing sensitive information for charitable institutions.
Organizations should consider the urgency of addressing this vulnerability based on its CVSS score and the potential for exploitation. Although it is currently not known to be actively exploited, the nature of XSS vulnerabilities necessitates immediate remediation to avoid future incidents. Organizations should address in priority patch cycle.

Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The WeGIA application is affected in all versions prior to 3.2.8. Organizations should ensure they update to this version to mitigate the identified vulnerability.
Mitigation & Remediation
Organizations should prioritize patching by upgrading to WeGIA version 3.2.8. If immediate patching is not feasible, consider implementing web application firewalls to filter out potentially malicious requests. Proper input validation and output encoding should be enforced in the application to mitigate XSS vulnerabilities.
For further assistance, organizations may benefit from engaging in penetration testing services to evaluate their security posture.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor application logs for unusual activity, especially around the `avulso` parameter. Behavioral anomalies such as unexpected redirects or script execution should be investigated. Network signatures that align with XSS attack patterns can also provide detection capabilities.
AppSecure Threat Intelligence Insight
The long-term significance of this vulnerability within the WeGIA application highlights the ongoing risks associated with web applications that do not adequately sanitize user inputs. It represents a broader trend of increasing XSS vulnerabilities in web applications.
Security teams should leverage this incident to enhance their security measures and ensure robust security practices are in place. Organizations must also recognize the importance of regular vulnerability assessments and timely patching to mitigate risks effectively.
For further reading on application security practices, organizations can consult resources on vulnerability management programs, web application penetration testing, and penetration testing methodologies to strengthen their defenses.
