Security readout for executives and security teams
Plain-English summary
An authenticated, non-administrative user could read arbitrary files from ASUSTOR Data Master 3.1.5 and earlier by targeting loginimage.cgi with a full file path. This can expose sensitive NAS data or system files despite limited account privileges.
Executive priority
Treat this as a targeted data exposure risk for affected NAS systems. Prioritize externally reachable or shared-user deployments first, then follow vendor guidance because the provided sources do not name a specific patch.
Technical view
CVE-2018-15698 is an authenticated arbitrary file read issue in ASUSTOR Data Master 3.1.5 and below. The source states loginimage.cgi accepts a full path and returns files from the filesystem to remote non-admin users. No CVSS, CWE, patch version, or exploit evidence is included.
Likely exposure
Exposure is likely limited to ASUSTOR Data Master deployments at version 3.1.5 or below where remote users can authenticate to the ADM web interface, including non-administrative accounts.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation. The issue requires authentication, but it weakens role separation because a non-admin user may read files they should not access.
Researcher notes
Evidence is narrow but clear: authenticated non-admin arbitrary file read through loginimage.cgi on ADM 3.1.5 and below. Missing data includes CVSS, CWE, fixed release, affected platform scope beyond ADM, and observed exploitation.
Mitigation direction
- Inventory ASUSTOR Data Master systems and identify versions 3.1.5 or below.
- Check ASUSTOR and Tenable guidance for fixed versions or vendor-approved remediation.
- Limit ADM web access to trusted networks or VPN where feasible.
- Review non-admin account necessity and remove stale accounts.
- Monitor for suspicious loginimage.cgi access patterns.
Validation and detection
- Confirm ADM version on each ASUSTOR device.
- Identify whether non-admin users can authenticate to affected ADM instances.
- Review web logs for loginimage.cgi requests referencing filesystem paths.
- Check whether sensitive file access occurred from non-admin sessions.
- Document internet-exposed or broadly reachable ADM interfaces.
