CVE-2018-10207: n/a in n/a
An issue was discovered in Vaultize Enterprise File Sharing 17.05.31. An attacker can exploit Missing Authorization on the FlexPaperViewer SWF reader, and export files that should have been restricted, via vectors involving page-by-page access to a document in SWF format.
AI Analysis
Technical Summary
CVE-2018-10207 is a vulnerability discovered in Vaultize Enterprise File Sharing version 17.05.31, specifically involving the FlexPaperViewer SWF reader component. The core issue is a Missing Authorization flaw that allows an attacker to bypass access controls and export files that should be restricted. This is achieved through vectors that exploit page-by-page access to documents rendered in SWF (Shockwave Flash) format. Essentially, the vulnerability enables unauthorized users to access and extract sensitive content from protected documents by manipulating the viewer's handling of SWF files. Since the vulnerability is tied to the FlexPaperViewer SWF reader, it leverages the legacy Flash format, which is known for multiple security concerns. The absence of a CVSS score indicates that the vulnerability has not been formally scored, but the technical details confirm that the flaw allows unauthorized data exfiltration without proper permission checks. No patches or known exploits in the wild have been reported, but the risk remains significant due to the nature of the missing authorization and the sensitivity of enterprise file sharing platforms.
Potential Impact
For European organizations, this vulnerability poses a considerable risk to confidentiality and data integrity. Vaultize Enterprise File Sharing is used to securely share and manage sensitive documents, often containing personal data, intellectual property, or confidential business information. Exploitation of this vulnerability could lead to unauthorized disclosure of sensitive files, violating GDPR requirements and potentially resulting in regulatory penalties and reputational damage. The ability to export restricted files page-by-page increases the risk of partial or full data leakage. Additionally, organizations relying on legacy Flash-based document viewers may face increased exposure due to the deprecated and insecure nature of SWF files. The lack of authentication bypass means that even users with limited or no privileges could potentially exploit this flaw, increasing the attack surface. This vulnerability could also undermine trust in secure file sharing solutions, impacting collaboration and operational efficiency.
Mitigation Recommendations
To mitigate this vulnerability, European organizations should first verify if they are using Vaultize Enterprise File Sharing version 17.05.31 or any other affected versions with the FlexPaperViewer SWF reader. Immediate steps include disabling or restricting the use of SWF format documents within the platform, as Flash is deprecated and inherently insecure. Organizations should migrate to more secure document formats such as PDF or HTML5-based viewers that enforce strict authorization checks. If possible, disable the FlexPaperViewer component or replace it with a modern viewer that supports robust access control. Implement strict access control policies and monitor file access logs for unusual activity, especially page-by-page document exports. Network segmentation and application-layer firewalls can help limit exposure. Since no official patches are listed, organizations should contact Vaultize support for guidance or consider upgrading to newer, patched versions of the software. Finally, conduct regular security assessments and penetration testing focused on file sharing platforms to detect similar authorization issues.
