Summary

An improper ownership management vulnerability in Moxa's Secure Router allows a low-privileged authenticated user to access a configuration file containing the hashed password of the administrative account. Exploitation is only possible when the configuration file has been exported, and it does not impact integrity or availability.

Risk Assessment

An attacker could obtain sensitive information (the administrator password hash), facilitating further attacks on the device.

Recommendation

Restrict access to exported configuration files and consider rotating the administrative password; monitor vendor updates.

Other vulnerabilities in Moxa Secure Router
