A vulnerability in the command-line interface (CLI) parser of Cisco NX-OS Software could allow an authenticated, local malicious user to create files in any location that they have access. The vulnerability is due to improper input filtering of file name input. An attacker could exploit this vulnerability by including a relative path in the file name parameter. A successful exploit could allow the malicious user to write arbitrary scripts to any part of the file system, which an administrator could execute inadvertently. 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 malicious user 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.
