Technical description

A vulnerability in the change password API of Cisco Connected Mobile Experiences (CMX) could allow an authenticated, remote attacker to alter their own password to a value that does not comply with the strong authentication requirements that are configured on an affected device. This vulnerability exists because a password policy check is incomplete at the time a password is changed at server side using the API. An attacker could exploit this vulnerability by sending a specially crafted API request to the affected device. A successful exploit could allow the attacker to change their own password to a value that does not comply with the configured strong authentication requirements.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
