CVE-2024-20458Network attack vector

Unauthenticated configuration and firmware modification via HTTP endpoints

Published Oct 16, 2024 · Updated Oct 16, 2024

Authentication bypass in Cisco ATA 190 Series firmware allows remote attackers to view or delete configuration or change firmware. Specific HTTP endpoints in the web-based management interface perform these sensitive operations without authenticating the request. Network reachability to the interface is sufficient; it is disabled by default only on ATA 191 on-premises firmware, and impact is limited to configuration disclosure or deletion and firmware replacement.
