CyberRota Analysis

AI-Generated

The Kaon AR2140X router is vulnerable due to its backup functionality being accessible without authentication, allowing unauthenticated remote attackers to trigger a configuration backup. This exploitation can lead to the retrieval of sensitive configuration data and render the router inoperable for an extended period. Organizations using affected firmware versions (up to 4.2.17) should prioritize immediate remediation to mitigate potential disruptions and data exposure.

Original NVD Description

The Kaon AR2140X router contains a vulnerability where the backup functionality is accessible without authentication. This allows an unauthenticated remote attacker to trigger a configuration backup and retrieve it in a form encrypted by a device-specific key. Triggering this function renders the router inoperable for a substantial period of time.  This issue was identified in firmware versions up to 4.2.17. Status of newer versions remains unknown.
