A medium-severity Stored Cross-Site Scripting (XSS) vulnerability has been identified in WeGIA, an open-source web manager primarily used by charitable institutions and focused on the Portuguese language. This vulnerability allows attackers to inject malicious scripts into the `tipo` parameter of the `adicionar_tipo_quadro_horario.php` endpoint. Due to the application's failure to validate and sanitize user inputs properly, the injected scripts are stored on the server and executed automatically whenever the affected page is accessed by users.
The vulnerability was published on January 14, 2025, and has been assigned a CVSS score of 6.4, indicating a medium severity level. This score reflects the risk posed by the potential for attackers to exploit this vulnerability to execute malicious scripts in the users' browsers. Such exploitation could lead to the compromise of sensitive user data and systems.
Currently, there are no known workarounds for this vulnerability. Therefore, organizations utilizing WeGIA are urged to upgrade to version 3.2.6, which addresses this security issue. Delaying the implementation of this patch could expose users to significant security risks.
As attackers may leverage this vulnerability to exploit unsuspecting users, organizations should prioritize patching immediately. This proactive approach is essential to safeguard against potential data breaches and maintain the integrity of user interactions.
Vulnerability Details
The vulnerability allows for the injection of malicious scripts due to inadequate input validation and sanitization in the `adicionar_tipo_quadro_horario.php` parameter. The vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting').
The CVSS score of 6.4 indicates that the vulnerability has a medium severity level. This level of severity necessitates attention from organizations using the affected version of WeGIA, as it can lead to potential security breaches.
Technical Analysis
The root cause of this vulnerability is the failure to properly validate and sanitize user inputs on the specified endpoint. The attack vector is network-based, and the complexity is categorized as low, meaning that an attacker does not require extensive effort to exploit this vulnerability.
No privileges are required for the attack, but user interaction is necessary, as the malicious script is executed in the user's browser upon accessing the affected page. The potential impacts are significant, with confidentiality and integrity impacts rated as low, but the availability impact is assessed as none.
Risk & Impact Analysis
The real-world risk associated with this vulnerability primarily stems from the possibility of data theft and unauthorized actions taken on behalf of the user. Given the nature of the application, which serves charitable institutions, the potential for reputational damage and loss of trust is considerable.
Organizations utilizing WeGIA must understand the urgency of addressing this vulnerability as part of their security posture. The CVSS score and the potential exploitation risk signify that this issue should be treated with a high level of priority.
