A vulnerability in Cisco NX-OS Software could allow an authenticated, remote attacker to view sensitive information.

The vulnerability is due to improper sanitization of configuration files that can be viewed by users assigned to the network-operator role. An attacker could exploit this vulnerability by accessing the Cisco NX-OS management interface as a network-operator. A successful exploit could allow the attacker to view sensitive information in the Cisco NX-OS configuration files.

Cisco has confirmed the vulnerability in a security notice and has released software updates.

To exploit this vulnerability, an attacker requires authenticated access to the targeted system. Authenticated access may require the attacker to access trusted, internal networks. These access requirements could limit the likelihood of a successful exploit.

Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
