Title
Missing Authentication for Critical Function vulnerability in Anritsu Remote Spectrum Monitor
Summary
The MS27102A Remote Spectrum Monitor is vulnerable to an authentication bypass that allows unauthorized users to access and manipulate its management interface. Because the device provides no mechanism to enable or configure authentication, the issue is inherent to its design rather than a deployment error.
