AnalysisAIv2 – Jul 26, 2026

Path traversal in the file upload handler of Yottamaster DM2, DM3, and DM200 NAS firmware (up to 1.2.23/1.9.12) allows remote authenticated attackers with low privileges to write arbitrary files to unintended directories. Exploit code is publicly available, though EPSS (0.24%) indicates low probability of widespread exploitation, and no active exploitation has been reported.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.
