A vulnerability in the license installation module of the Cisco Nexus 1000V could allow an authenticated, local attacker to execute arbitrary shell commands. The vulnerability is due to a failure of the install all iso command to properly validate user-supplied input. An attacker could exploit this vulnerability by providing crafted arguments to the install all iso command. Cisco has confirmed the vulnerability in a security notice and released software updates. To exploit this vulnerability, an attacker would need local access to the targeted device, which decreases 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.
The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory.
