CVE-2024-25182 identifies a critical file upload vulnerability in VvvebJs version 1.7.2, specifically via the save.php script. VvvebJs is a web page builder JavaScript library used to create drag-and-drop web content. The vulnerability falls under CWE-434 (Unrestricted Upload of File with Dangerous Type), allowing attackers to upload malicious files without authentication or user interaction. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) indicates network attack vector, low attack complexity, no privileges or user interaction required, and full impact on confidentiality, integrity, and availability. Exploitation could lead to remote code execution, data theft, or complete system takeover. Although no public exploits are reported yet, the critical nature and ease of exploitation make it a high-risk threat. The lack of available patches at the time of publication necessitates immediate mitigation through configuration changes and monitoring. Organizations using VvvebJs in their web infrastructure should audit their deployments and restrict file upload capabilities to trusted users and file types.

For European organizations, this vulnerability poses a significant risk to web applications utilizing VvvebJs 1.7.2, particularly those exposing the save.php endpoint publicly. Successful exploitation can lead to unauthorized remote code execution, enabling attackers to compromise sensitive data, disrupt services, or pivot within networks. This can result in data breaches, loss of customer trust, regulatory penalties under GDPR, and operational downtime. Sectors with high web presence such as e-commerce, media, and government services are especially vulnerable. The critical severity and lack of required authentication mean attackers can exploit this at scale, potentially impacting multiple organizations simultaneously. The threat also increases the risk of ransomware deployment or supply chain attacks if compromised systems are used as launchpads.

1. Immediately audit all web applications using VvvebJs 1.7.2 to identify instances of the vulnerable save.php endpoint. 2. Implement strict server-side validation to restrict file uploads by type, size, and content, allowing only safe file formats. 3. Disable direct execution permissions on upload directories to prevent execution of uploaded malicious files. 4. Employ web application firewalls (WAFs) with rules to detect and block suspicious file upload attempts targeting save.php. 5. Monitor logs for unusual upload activity or access patterns to detect exploitation attempts early. 6. Isolate affected web servers in segmented network zones to limit lateral movement if compromised. 7. Stay alert for official patches or updates from VvvebJs maintainers and apply them promptly once released. 8. Educate development teams on secure file upload practices and the risks of CWE-434 vulnerabilities. 9. Consider temporary disabling or restricting the save.php functionality if feasible until a patch is available.
