DescriptionCVE.org

MRCMS V3.1.2 contains an unauthenticated directory enumeration vulnerability in the file management module. The /admin/file/list.do endpoint lacks authentication controls and proper input validation, allowing remote attackers to enumerate directory contents on the server without any credentials.

AnalysisAI

Unauthenticated directory enumeration in MRCMS V3.1.2 allows remote attackers to list and discover directory contents through the /admin/file/list.do endpoint without credentials. The vulnerability stems from missing authentication controls and input validation in the file management module, enabling information disclosure that can facilitate reconnaissance for follow-on attacks.

Technical ContextAI

MRCMS (Mushroom CMS) is a content management system with a file management module that exposes administrative file listing functionality at the /admin/file/list.do endpoint. The root cause is a missing authentication gate on an administrative endpoint that should require user credentials and session validation before processing requests. The endpoint fails to implement proper access controls to restrict file enumeration operations to authenticated and authorized users, resulting in CWE-862 (Missing Authorization) or related missing authentication issues. Without proper input validation, the endpoint may also be susceptible to path traversal techniques that could extend the scope of directory enumeration beyond the intended directory structure.

RemediationAI

Immediately upgrade MRCMS to a patched version released after 3.1.2; specific patched version number is not provided in available advisory data, so consult the official Mushroom CMS GitHub repository (https://github.com/wuweiit/mushroom) for the latest stable release. As an immediate workaround pending upgrade, implement network-level access controls to restrict HTTP requests to the /admin/file/list.do endpoint to trusted internal IP ranges only, and disable or remove the endpoint if not actively required. Apply web application firewall (WAF) rules to block requests to /admin/file/* paths from untrusted sources. Additionally, audit all previous log entries to the file/list.do endpoint to identify if reconnaissance activity has already occurred, and review directory listings for sensitive files that may have been exposed.
