Multiple privilege escalation vulnerabilities in the Python subsystem of Cisco Nexus devices running Cisco NX-OS Software could allow an authenticated, local attacker to gain elevated privileges. The vulnerabilities are due to insufficient hardening of the operating system on which NX-OS is based. An attacker who has sufficient privileges to execute arbitrary Python scripts on an affected device could use this access to obtain root privileges. Cisco has confirmed the vulnerability; however, software updates are not available. To exploit these vulnerabilities, an attacker must have local access and authenticate to the targeted device. These requirements could limit the possibility of a successful exploit. Cisco would like to thank Jens Krabbenhoeft for discovering and reporting this vulnerability.
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.
