CVE-2025-22617 in WeGIA
Summary
by MITRE • 01/13/2025
WeGIA is an open source web manager with a focus on the Portuguese language and charitable institutions. A Reflected Cross-Site Scripting (XSS) vulnerability was identified in the `editar_socio.php` endpoint of the WeGIA application. This vulnerability allows attackers to inject malicious scripts in the `socio` parameter. The application fails to validate and sanitize user inputs in the `socio` parameter. This lack of validation permits the injection of malicious payloads, which are reflected back to the user's browser in the server's response and executed within the context of the victim's browser. This issue has been addressed in version 3.2.7 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

The CVE-2025-22617 vulnerability represents a critical reflected cross-site scripting flaw within the WeGIA web management platform, a system specifically designed for Portuguese-speaking charitable organizations. This vulnerability exists within the `editar_socio.php` endpoint, which handles member editing functionality within the application's administrative interface. The flaw stems from inadequate input validation and sanitization processes that fail to properly filter user-supplied data before incorporating it into server responses. The vulnerability specifically affects the `socio` parameter, which serves as the primary injection vector for malicious script execution. The WeGIA platform, being an open-source solution, serves charitable institutions that may have limited cybersecurity resources, making this vulnerability particularly concerning for organizations that rely on the system for member management and administrative functions.
The technical implementation of this reflected XSS vulnerability follows the classic attack pattern where malicious input is accepted through the `socio` parameter and subsequently reflected back to the user's browser without proper sanitization. When an attacker crafts a malicious payload and submits it through this parameter, the application processes the input without adequate validation mechanisms, allowing the payload to be embedded directly into the server's HTTP response. Upon the victim user accessing the affected page, the malicious script executes within their browser context, potentially enabling session hijacking, credential theft, or redirection to malicious websites. This vulnerability falls under CWE-79, which specifically addresses Cross-Site Scripting flaws, and aligns with ATT&CK technique T1531 for "Modify System Image" and T1566 for "Phishing", as the attack vector can be used to establish persistent access or manipulate system behavior through browser-based exploitation. The reflected nature of this vulnerability means that the malicious script must be injected by an attacker and then triggered by a victim, making it particularly dangerous in environments where users may be tricked into clicking malicious links or visiting compromised pages.
The operational impact of this vulnerability extends beyond simple script execution, as it can enable attackers to compromise the integrity of the charitable organization's administrative system. Given that WeGIA serves charitable institutions, the potential for data theft, member information compromise, or system manipulation poses significant risks to organizational operations and donor trust. Attackers could potentially access sensitive member data, modify membership records, or establish persistent access through session manipulation. The vulnerability's presence in a web management system designed for charitable organizations means that the attack surface includes not just technical personnel but also volunteers and staff who may interact with the system. The lack of known workarounds forces organizations to rely entirely on the official patch, which was implemented in version 3.2.7, highlighting the importance of maintaining current software versions and implementing proper patch management procedures. This vulnerability demonstrates the critical need for input validation and output encoding in web applications, particularly those serving organizations that handle sensitive personal information and financial data.
Organizations utilizing WeGIA must prioritize immediate upgrade to version 3.2.7 or later to mitigate this reflected XSS vulnerability, as the attack surface remains unpatched in older versions. The remediation process should include comprehensive testing of the updated system to ensure that no regression issues have been introduced. Security teams should implement additional monitoring for suspicious user activity or unusual parameter submissions that might indicate exploitation attempts. The vulnerability's classification under CWE-79 and its alignment with ATT&CK techniques emphasize the need for comprehensive web application security controls including input validation, output encoding, and proper content security policies. Organizations should also consider implementing web application firewalls or security headers to provide additional protection layers. The incident underscores the importance of regular security assessments for open-source projects, particularly those handling sensitive data for charitable organizations, as these systems often receive less rigorous security scrutiny than commercial alternatives. Furthermore, the vulnerability highlights the necessity of maintaining security awareness training for users who interact with web-based administrative systems, as social engineering attacks leveraging such XSS vulnerabilities often rely on user interaction to achieve their objectives.
