CVE-2023-43119Network attack vector

Root filesystem control via Redis Telnet commands

Published Oct 16, 2023 · Updated Sep 17, 2024

Incorrect authorization in Extreme Networks Switch Engine allows remote attackers to perform arbitrary filesystem operations as root via Telnet. The Telnet command path reaches the Redis server with root privilege and fails to restrict attacker-controlled filesystem operations. Network reachability of the Telnet service is required, and successful exploitation grants root-level file creation, modification, or deletion.
