The CVE-2025-23664 vulnerability represents a critical security flaw in the Real Seguro Viagem web application that combines Cross-Site Request Forgery and Stored Cross-Site Scripting exploits. This dual vulnerability arises from inadequate input validation and insufficient anti-CSRF protection mechanisms within the application's authentication and data handling processes. The vulnerability exists across all versions from the initial release through version 2.0.5, indicating a persistent flaw in the application's security architecture that has not been adequately addressed in the current codebase.
The technical implementation of this vulnerability stems from the application's failure to properly validate and sanitize user input before storing and rendering it within web pages. When users submit data through web forms or API endpoints, the application accepts and stores this input without adequate sanitization measures. The CSRF protection mechanisms are either absent or insufficiently implemented, allowing malicious actors to craft requests that can be executed by authenticated users without their knowledge or consent. This creates a perfect storm where an attacker can first establish a CSRF attack vector and then leverage the stored data to execute malicious scripts in the context of authenticated sessions.
The operational impact of this vulnerability is severe and multifaceted. An attacker who successfully exploits this vulnerability can execute arbitrary JavaScript code within the context of any authenticated user's browser session. This enables a range of malicious activities including but not limited to session hijacking, credential theft, data exfiltration, and privilege escalation. The stored XSS component means that malicious scripts persist in the application's database and will execute whenever affected pages are loaded, creating a long-term threat that can affect multiple users over time. The vulnerability particularly impacts users who have elevated privileges or access to sensitive data within the insurance application's framework.
This vulnerability aligns with CWE-352, which specifically addresses Cross-Site Request Forgery, and CWE-79, which covers Cross-Site Scripting. The ATT&CK framework categorizes this under T1566 for Initial Access through malicious web content and T1059 for command and control through scripting. The vulnerability demonstrates a failure in implementing proper security controls such as CSRF tokens, input sanitization, and output encoding. Organizations should immediately implement comprehensive mitigations including the deployment of anti-CSRF tokens for all state-changing operations, robust input validation and sanitization procedures, and proper output encoding to prevent script execution. Additionally, regular security assessments and code reviews should be conducted to identify and remediate similar vulnerabilities in the application's architecture.
