CVE-2026-9778
HighCVSS 7.2Exploitation Probability (EPSS)
Elevated risk71th percentile - higher than 71% of all known CVEs
Summary
A directory traversal vulnerability in the ImportDeviceList method of ATEN Unizon allows remote code execution. The issue stems from improper validation of a user-supplied path before using it in file operations. Authentication is required for exploitation.
Risk Assessment
An attacker can gain full system control in the SYSTEM context, leading to infrastructure compromise and potential access to sensitive data.
Recommendation
Apply the vendor-supplied update immediately and restrict administrative interface access to trusted users only.
