CVE-2026-67247 ASUSTOR Inc. CVE debrief

Who should care

Defenders responsible for Asustor ADM systems, particularly those in versions 4.1.0 through 4.3.3.RUN1 and 5.0.0 through 5.1.3.RI81, should assess exposure and prioritize remediation.

Why it matters

This path traversal vulnerability in Asustor ADM allows authenticated attackers to access unintended filesystem paths or log database files, potentially leading to data exposure or unauthorized system access. Defenders should prioritize verifying and remediating vulnerable systems, implementing input validation and sanitization, and monitoring system logs for potential exploitation attempts.

• Authenticated attackers can access unintended filesystem paths or log database files
• Potential for data exposure or unauthorized system access
• Requires verification of vulnerable systems and remediation
• Monitoring system logs for potential exploitation attempts is necessary

Technical summary

The path traversal vulnerability in Asustor ADM occurs because user-controlled disk serial input is not sufficiently validated before being used to construct the path of an IHM log database file. This allows an authenticated attacker to access unintended filesystem paths or log database files. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.RUN1 as well as from ADM 5.0.0 through ADM 5.1.3.RI81. Defenders should prioritize verifying and remediating vulnerable systems, implementing input validation and sanitization, and monitoring system logs for potential exploitation attempts.

Defensive priority

Defenders should prioritize verifying and remediating this vulnerability in Asustor ADM 4.1.0 through 4.3.3.RUN1 and 5.0.0 through 5.1.3.RI81 systems, as it allows an authenticated attacker to access unintended filesystem paths or log database files.

Recommended defensive actions

• Verify and remediate vulnerable Asustor ADM systems
• Implement input validation and sanitization for disk serial input
• Monitor system logs for potential exploitation attempts
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and NVD vulnerability detail provide information on the path traversal vulnerability in Asustor ADM. The vendor advisory from Asustor is also available. Defenders should verify the vulnerability in Asustor ADM 4.1.0 through 4.3.3.RUN1 and 5.0.0 through 5.1.3.RI81 systems. Evidence is limited to CVE and NVD details; further verification is required.
