CVE-2024-20459Network attack vector

Root command execution via unsanitized web requests

Published Oct 16, 2024 · Updated Oct 16, 2024

OS command injection in Cisco ATA 191 and 192 Multiplatform firmware 11.2.4 and earlier allows remote authenticated users to execute commands as root. The web-based management interface passes fields from a malicious request to operating-system commands without adequate input sanitization. Administrative privileges and access to the management interface are required; successful exploitation grants root-level control of the device.
