CVE-2024-57030 is a Cross Site Scripting (XSS) vulnerability identified in Wegia versions earlier than 3.2.0, specifically in the /geral/documentos_funcionario.php script via the id parameter. XSS vulnerabilities arise when an application includes untrusted data in a web page without proper validation or escaping, enabling attackers to execute arbitrary JavaScript in the context of the victim's browser. This vulnerability allows remote attackers to inject malicious scripts that can compromise user sessions, steal cookies, redirect users to malicious sites, or perform actions on behalf of the user. The CVSS 3.1 score of 8.1 reflects a high severity due to the vulnerability's network attack vector (AV:N), high impact on confidentiality, integrity, and availability (C:H/I:H/A:H), and no requirement for privileges or user interaction (PR:N/UI:N). The attack complexity is high (AC:H), indicating some difficulty in exploitation, possibly due to the need for specific crafted input or conditions. No patches or fixes are currently linked, and no known exploits have been reported in the wild, but the vulnerability's presence in a web-facing component makes it a critical risk. The CWE-79 classification confirms this as a classic XSS issue, emphasizing the need for proper input sanitization and output encoding in web applications.

The impact of CVE-2024-57030 on organizations worldwide can be severe. Successful exploitation can lead to the compromise of user credentials, session hijacking, unauthorized actions performed on behalf of legitimate users, and potential spread of malware through injected scripts. This can result in data breaches, loss of user trust, reputational damage, and regulatory penalties, especially if sensitive employee or organizational data is exposed. Since the vulnerability affects a web application component, it can be exploited remotely without authentication or user interaction, increasing the attack surface. Organizations relying on Wegia for employee document management or related functions may face operational disruptions and increased risk of targeted attacks. The high CVSS score underscores the critical nature of the threat, and the absence of known exploits should not lead to complacency, as attackers may develop exploits rapidly once the vulnerability is public.

To mitigate CVE-2024-57030, organizations should immediately upgrade Wegia to version 3.2.0 or later once available, as this likely contains the necessary patches. In the absence of an official patch, implement strict input validation and sanitization on the id parameter in /geral/documentos_funcionario.php to neutralize malicious scripts. Employ output encoding techniques to ensure that any user-supplied data rendered in the browser is treated as data, not executable code. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block XSS attack patterns targeting this endpoint. Conduct thorough code reviews and security testing focusing on injection points. Additionally, educate users about the risks of XSS and monitor logs for suspicious activities related to the vulnerable parameter. Regularly update and patch all web-facing applications and maintain an incident response plan to quickly address potential exploitation attempts.
