CVE-2020-25838
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUnauthorized disclosure of sensitive information vulnerability in Micro Focus Filr product. Affecting all 3.x and 4.x versions. The vulnerability could be exploited to disclose unauthorized sensitive information.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceMicro Focus Filr versions 3.x and 4.x contain an unauthorized disclosure vulnerability allowing attackers to access sensitive information without proper authorization. The specific attack vector and exact nature of exposed data are not detailed in available documentation. This represents a classic information disclosure flaw in the enterprise file synchronization and sharing platform.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed Filr versionAccess the Filr admin console and navigate to System Administration > About, or run the command: /opt/filr/bin/filrctl status --version. Alternatively, check the RPM package: rpm -qa | grep filr-coreAffected if The version number is 3.0 through 3.4.7 (inclusive), or 4.0 through 4.2.1.1.0 (inclusive)
-
Verify the Filr web service is accessibleConfirm the Filr web interface is reachable at the configured hostname/IP. The vulnerability affects the web-facing component, so an inaccessible or disabled web service would not be exploitableAffected if The Filr web application is running and accessible from network segments containing potential attackers
-
Review user access control assignmentsIn Filr admin console, navigate to Users and Groups > User Management. Examine all user accounts and their assigned roles, particularly focusing on external users or users with elevated file access privilegesAffected if Users exist with permissions beyond what their role requires, or external/untrusted accounts have been granted access to sensitive directories
-
Inspect audit logs for unauthorized file accessIn Filr admin console, go to Reports > Audit Log. Search for file access events from unexpected IP ranges, after-hours access, or access to files outside normal user responsibilitiesAffected if Audit logs show file access events that cannot be explained by legitimate user activity, or access to sensitive files by users who should not have that access
-
Check API endpoint exposureReview Filr server configuration files in /etc/filr/ and the Apache reverse proxy configuration in /etc/httpd/conf.d/filr.conf. Look for any custom API endpoints or modified access rules that may expose additional file system pathsAffected if Non-standard API endpoints are configured or the configuration shows relaxed access controls beyond default Filr settings
A user is affected if their Filr installation runs version 3.0-3.4.7 or 4.0-4.2.1.1.0 AND the web interface is accessible, regardless of access control configuration, as the vulnerability allows unauthorized information disclosure by design.
