CVE-2023-31459

Administrative command execution via unchanged default password

Published May 24, 2023 · Updated Jan 31, 2025

Default credentials in Mitel MiVoice Connect 9.6.2208.101 and earlier allow remote attackers to gain administrative access. The Connect Mobility Router's initial installation leaves an administrative password unchanged instead of enforcing a replacement. An attacker with internal network access can authenticate as an administrator, alter arbitrary configuration, and execute arbitrary commands.
