CVE-2023-20039

Sensitive data disclosure via permissive directory permissions

Published Nov 15, 2024 · Updated Nov 15, 2024

Improper file permissions in Cisco Industrial Network Director 1.11.2 and earlier allow local users to read sensitive application data. The installer applies overly permissive default access controls to the application data directory, exposing its files to low-privileged Windows accounts. Exploitation requires authenticated local access to the Windows host and is limited to disclosure of data stored in that directory.
