What is CVE-2025-34093?

A command injection vulnerability affects the Polycom HDX Series command shell interface via Telnet. The 'lan traceroute' command in the devcmds console does not properly sanitize user input, allowing attackers to inject shell metacharacters. This can lead to remote code execution under the root user context, particularly when Telnet access is enabled, or if credentials are available. Organizations using these affected products must take swift action to mitigate the risks associated with this vulnerability.
