WeGIA, an open-source web manager catering to Portuguese language and charitable organizations, has been found to have a Stored Cross-Site Scripting (XSS) vulnerability within the `informacao_adicional.php` endpoint. This vulnerability allows attackers to inject malicious scripts into the `descricao` parameter. The issue arises from inadequate validation and sanitization of user inputs.
The injected scripts are stored on the server and executed automatically when the affected page is accessed, posing a significant security risk. As a result, this vulnerability could lead to the compromise of user data and systems. This issue has been addressed in version 3.2.6, and all users are strongly advised to upgrade. There are no known workarounds for this vulnerability.
Given the potential impact of this vulnerability, organizations utilizing WeGIA should prioritize the patching process immediately to ensure their systems are secure against possible exploitation.
The base CVSS score for this vulnerability is 6.4, classified as medium severity, which underscores the importance of addressing this issue promptly.
Vulnerability Details
The official CVE description notes that this vulnerability allows attackers to inject malicious scripts into the `descricao` parameter of the WeGIA application. The weakness is classified under CWE-79, which pertains to improper neutralization of input. It has been assigned a CVSS score of 6.4, with a medium severity interpretation, indicating that while the vulnerability may not be easily exploitable, it presents a significant risk if successfully executed.
The vulnerability affects all versions of WeGIA prior to 3.2.6, which was released to address this issue. The vulnerability was published on January 13, 2025, and the application’s lack of input validation and sanitization has been identified as the root cause.
Technical Analysis
The root cause of this vulnerability is the failure to properly validate and sanitize user inputs in the `informacao_adicional.php` endpoint. The attack vector is categorized as network-based, indicating that attackers can exploit this vulnerability remotely.
The attack complexity is considered low, meaning that no specialized knowledge or skills are required to exploit the vulnerability, and it requires active user interaction to trigger the malicious payload.
The attack does not require any privileges. The potential impacts on confidentiality and integrity are both classified as low, while availability is not affected. Successful exploitation could compromise user data, leading to significant risks for organizations utilizing the application.
Risk & Impact Analysis
Risk to organizations includes potential data breaches and unauthorized access to user information. The blast radius is significant, as any user accessing the vulnerable endpoint could be affected. Given the medium severity rating, organizations should address this vulnerability in their priority patch cycle.
With no known public exploits or workarounds available, the urgency for remediation increases. Organizations should prioritize patching immediately to mitigate risks associated with this vulnerability.
