Technical ContextAI · show details

Classified as CWE-284 (Improper Access Control). Affects Filerise. FileRise is a self-hosted web file manager / WebDAV server. Versions prior to 3.3.0, the application contains an unauthenticated file read vulnerability due to the lack of access control on the /uploads directory. Files uploaded to this directory can be accessed directly by any user who knows or can guess the file path, without requiring authentication. As a result, sensitive data could be exposed, and privacy may be breached. This vulnerability is fixed in 3.3.0.

HIGH 7.5

DescriptionGitHub Advisory

FileRise is a self-hosted web file manager / WebDAV server. Versions prior to 3.3.0, the application contains an unauthenticated file read vulnerability due to the lack of access control on the /uploads directory. Files uploaded to this directory can be accessed directly by any user who knows or can guess the file path, without requiring authentication. As a result, sensitive data could be exposed, and privacy may be breached. This vulnerability is fixed in 3.3.0.

Executive ViewAI

Why It Matters

FileRise installations running versions prior to 3.3.0 are exposed to unauthenticated file read attacks, allowing attackers to access sensitive documents stored in the /uploads directory without credentials. This vulnerability affects any organization using self-hosted FileRise deployments and poses an immediate risk of confidential data exposure.

Business Impact: High

Compensating Controls

Implement Web Application Firewall (WAF) rules to block unauthenticated requests to /uploads directory; restrict network access to FileRise instances using IP whitelisting or VPN requirements; disable WebDAV functionality if not actively used; move sensitive files outside the /uploads directory; implement file-level encryption; enable comprehensive access logging and monitoring for anomalous file retrieval patterns.
