CVE-2018-10212 is a vulnerability identified in Vaultize Enterprise File Sharing version 17.05.31. The core issue involves improper authorization controls within the application, which allows an attacker to create folders inside another user's account by manipulating the device value parameter. This vulnerability arises due to insufficient validation or enforcement of access controls when processing device identifiers or session tokens, enabling unauthorized actions across account boundaries. The flaw specifically permits unauthorized folder creation, which could be leveraged to clutter or manipulate another user's file space, potentially facilitating further attacks such as social engineering, data confusion, or preparation for privilege escalation. Although the vulnerability does not directly disclose or modify existing data, the ability to create folders in another user's account undermines the integrity of the file sharing environment and could lead to trust issues or indirect data exposure if combined with other vulnerabilities. The lack of a CVSS score and absence of known exploits in the wild suggest limited public exploitation but do not diminish the risk posed by the authorization bypass. The vulnerability affects a specific version of Vaultize Enterprise File Sharing, a product used for secure file sharing and collaboration, which is typically deployed in enterprise environments requiring strict data governance and access control.

For European organizations, this vulnerability could have several impacts. Enterprises relying on Vaultize for secure file sharing may face risks to data integrity and user trust, as unauthorized folder creation could disrupt workflows and lead to confusion or mismanagement of shared resources. While direct data theft or deletion is not indicated, the ability to manipulate folder structures across accounts could be exploited as a stepping stone for more sophisticated attacks or insider threats. Organizations in regulated sectors such as finance, healthcare, or government could face compliance challenges if unauthorized access leads to data governance violations. Additionally, the presence of this vulnerability could undermine confidence in the security posture of file sharing solutions, potentially affecting collaboration and productivity. The impact is heightened in environments where Vaultize is integrated with other identity and access management systems, as improper authorization may cascade into broader access control issues.

To mitigate this vulnerability, organizations should first verify if they are running the affected version (17.05.31) of Vaultize Enterprise File Sharing and prioritize upgrading to a patched or newer version where the authorization flaw is resolved. If an official patch is unavailable, implementing strict network segmentation and access controls to limit exposure of the Vaultize server is critical. Administrators should audit device and session management logs to detect anomalous folder creation activities and enforce multi-factor authentication to reduce the risk of compromised credentials being used to exploit the flaw. Additionally, reviewing and tightening authorization policies within the application configuration can help prevent unauthorized cross-account actions. Employing application-layer firewalls or intrusion detection systems to monitor and block suspicious API calls or parameter tampering attempts related to device values is recommended. Finally, educating users about potential social engineering risks stemming from unauthorized folder creation can reduce the likelihood of follow-on attacks.
