CVE-2025-27417 in WeGIA
Summary
by MITRE • 03/03/2025
WeGIA is an open source Web Manager for Institutions with a focus on Portuguese language users. A Stored Cross-Site Scripting (XSS) vulnerability was identified in the adicionar_status_atendido.php endpoint of the WeGIA application. This vulnerability allows attackers to inject malicious scripts into the status parameter. The injected scripts are stored on the server and executed automatically whenever the affected page is accessed by users, posing a significant security risk. This vulnerability is fixed in 3.2.16.

The WeGIA web application represents an open source content management system designed specifically for institutional use with Portuguese language support, making it a target for attackers seeking to exploit web application vulnerabilities in educational and administrative environments. The application's architecture includes various endpoints for managing institutional data and user interactions, with the adicionar_status_atendido.php endpoint serving as a critical component for handling status updates in the application's workflow. This particular endpoint processes status information for attended requests or services within the institutional management system, creating a potential attack surface where user input is processed and stored for later retrieval.
The identified stored cross-site scripting vulnerability resides in the handling of the status parameter within the adicionar_status_atendido.php endpoint, representing a classic CWE-079 vulnerability that enables attackers to inject malicious JavaScript code into the application's data storage mechanisms. The flaw occurs when the application fails to properly sanitize or encode user-supplied input before storing it in the database, allowing malicious scripts to be persisted and executed whenever the stored data is rendered in subsequent user sessions. This vulnerability specifically affects the status parameter processing, where attackers can craft malicious payloads that will execute in the context of other users who view the affected status updates, creating a persistent threat vector that can be exploited across multiple user sessions.
The operational impact of this vulnerability extends beyond simple script execution, creating a potential attack chain that can lead to complete session hijacking, data exfiltration, and privilege escalation within the institutional environment. When exploited, the stored XSS allows attackers to steal session cookies, redirect users to malicious domains, or inject additional malicious code that could compromise the entire institutional web application. The vulnerability's persistence means that once exploited, the malicious scripts continue to execute for all users who access the affected pages, potentially affecting hundreds or thousands of users within the institution's user base. This makes the vulnerability particularly dangerous in educational or government settings where the application may be used by multiple stakeholders including students, faculty, staff, and administrative personnel.
Mitigation strategies for this vulnerability should include immediate implementation of input validation and output encoding mechanisms within the application's codebase, specifically targeting the status parameter handling in the adicionar_status_atendido.php endpoint. The fix implemented in version 3.2.16 demonstrates proper input sanitization techniques that should be adopted across all user input fields within the application to prevent similar vulnerabilities. Organizations should also implement comprehensive web application firewall rules that can detect and block suspicious script patterns, maintain regular security updates and patch management processes, and conduct thorough code reviews focusing on input validation and output encoding practices. The vulnerability aligns with ATT&CK technique T1531 which involves the exploitation of web application vulnerabilities to gain unauthorized access to systems, and represents a critical security gap that requires immediate attention to prevent potential data breaches or system compromises within institutional environments.
